The Broad Topic of Arc Welding

man welds at the factory

Arc welding is the most typically utilized type of welding used in various industries. It involves using a special electrode coated with flux. The electrode is brought close to the workpiece, and an electrical charge is applied to create a powerful spark called an arc between the electrode and the workpiece.

The arc produces extremely high heat, causing the workpiece and the electrode to melt and fuse. This creates a strong joint between the two materials. Take a quick look at this graphic to better understand this process.

Remember that there are different ways to start the arc and complete the welding process, but the above should give a good understanding of how arc welding works.

MIG Welding

The history of MIG welding, also known as Gas Metal Arc Welding (GMAW), can be traced back to the early 1940s. It was developed due to the increasing demand for efficient and rapid welding techniques during World War II. The process was initially referred to as “hollow electrode welding” and gained popularity due to its ability to weld non-ferrous metals, especially aluminum and magnesium.

In MIG welding, a continuous wire electrode is fed through a welding gun, which is also equipped with a shielding gas nozzle. The electrode, made of a consumable metal wire, melts and joins the base metals, while the shielding gas, typically a mixture of argon and carbon dioxide, protects the molten weld pool from atmospheric contamination. This shielding gas creates a stable arc and ensures high-quality welds.

TIG Welding

TIG welding, also known as Gas Tungsten Arc Welding (GTAW), has a longstanding heritage. It emerged as a vital welding technique, particularly during World War II, when it became indispensable for welding critical components in various industries.

In TIG welding, a non-consumable tungsten electrode generates an arc. Unlike MIG welding, no filler metal is added automatically. Instead, the welder adds the filler metal manually, if necessary. A shielding gas, chosen from inert options like helium or argon, safeguards the weld zone by preventing atmospheric contamination. TIG welding offers excellent control over the welding process, making it suitable for applications that demand intricate welds and exceptional aesthetics.

Both MIG and TIG welding have undergone significant advancements over the years. Improvements in power sources, electrode materials, shielding gases, and welding techniques have further enhanced their efficiency and versatility. MIG and TIG welding continues to be widely utilized in various industries, including automotive, construction, aerospace, and manufacturing, due to their reliability, versatility, and ability to produce high-quality welds.

Electroslag Welding

Electroslag Welding - Types of Welding

Electroslag welding (ESW) is named so because of the unique slag-based process it employs. “Electro” refers to using electric current to generate heat, while “slag” refers to the molten layer of flux that forms during welding.

In ESW, an electric arc is established between a consumable electrode and the workpiece. The heat generated by the arc melts the electrode, and as it descends into the joint, a layer of molten slag is formed on top. This slag acts as a protective shield, preventing atmospheric contamination and maintaining the stability of the welding process.

The concept of ESW originated in the Soviet Union, where engineers were looking for efficient ways to weld large steel structures, such as ship components and heavy machinery parts. The first successful application of ESW occurred in the late 1940s, marking a significant milestone in welding technology.

Over the years, ESW has evolved and gained recognition for its ability to produce high-quality, defect-free welds in thick steel sections. It has found applications in various industries, including shipbuilding, nuclear power, and construction. Continuous advancements in equipment, electrode materials, and process control have further improved the efficiency and reliability of Electroslag welding, solidifying its position as a valuable technique for welding heavy steel components.

Friction Stir Welding

Friction Stir Welding (FSW) is a solid-state welding process invented and developed at The Welding Institute (TWI) in the United Kingdom in 1991. It was initially created as a method to join aluminum materials, but its applications have expanded to include other metals and alloys as well.

In FSW, a specially designed rotating tool with a unique pin and shoulder geometry is plunged into the joint between two workpieces. The rotation of the tool generates frictional heat, softening the material without reaching its melting point. The rotating tool then stirs the softened material, forming a solid-state bond as it cools.

FSW revolutionized the welding industry due to its ability to produce high-quality welds with numerous advantages. It eliminates issues associated with traditional fusion welding, such as distortion, porosity, and solidification defects. FSW also allows for the joining of dissimilar materials and can weld thick sections in a single pass without the need for additional filler materials.

Robotic welding utilizes a sophisticated robotic armature with multiple points of articulation, which are computer-directed, to weld metal sheets together. The robotic arm is equipped with optics that allow it to “see” the welded material, providing imagery that the program can use to identify pre-coded regions of the welded workpiece.

The robotic arm can move itself and the work platform to align the pieces properly, resulting in efficient and accurate welding.

In robotic welding, a movable platform may hold the item being welded and can change angles, swivel, and move in combination with the robot arm to fit any desired angle. At the end of the robotic arm is the arc welder, which follows the programmed pathway to tack and weld the fitted pieces together. 

Once the program is activated, the robot arm goes to work, welding the materials and moving itself and the work platform to align the piece properly. After welding, the welded piece is allowed to cool, and the next programmed item is clamped to the work platform for the next welding task.

Your Guide to Robotic Spot Welding

Robotic spot welding is a critical technique in metal fabrication, especially in the production of automobiles, appliances, and other metal products. It involves using robotic systems to apply pressure and pass an electric current through overlapping metal parts to create a strong and permanent bond.

As with any welding process, proper preparation, equipment, and technique are crucial for successful robotic spot welding. One of the benefits of using robotic systems is their ability to maintain consistent quality and precision, even with complex shapes and large production volumes. This helps ensure the longevity and reliability of the final product, as well as improve overall production efficiency.

To achieve optimal results with robotic spot welding, it is essential to properly program the robots, select appropriate welding parameters, and ensure proper alignment of the workpieces. Additionally, regular maintenance and calibration of the equipment are critical to ensure consistent performance and prevent downtime.

Robotic spot welding is a powerful tool for metal fabrication and offers significant advantages over manual spot welding. You can achieve efficient, high-quality results by understanding the process and following best practices.


What is Robotic Spot Welding

Robotic Resistance Spot Welding (RSW) is an advanced welding process that employs robots to weld two metal forms together by applying pressure and electric current to their overlapping parts. The process is sometimes referred to as spot welding and is characterized by welding a small area, or “spot,” at a time rather than welding an entire seam or joint.

Robotic spot welding involves using a welding machine and robots to generate and control the electric current that flows between two electrodes placed on either side of the metal component. The robots ensure precision in the welding process, producing a series of small, tightly controlled welds that create a strong and consistent bond between the metal pieces.

Robotic RSW is widely used in manufacturing automobiles, appliances, and various metal products, where high-quality, cost-effective, durable, and reliable products are required. One of the main advantages of using robots in spot welding is their ability to work with complex shapes and large production volumes while maintaining consistent quality and precision.

Advantages of Spot Welding:

  • Speed: Robotic spot welding is fast and efficient, ideal for high-volume production.
  • Strength: Robotic spot welding produces a strong, permanent bond between metal sheets, making it optimal for high-strength applications.
  • Cost-effectiveness: Robotic spot welding is cost-effective, requiring less material and labor than other welding methods.
  • Versatility: Spot welding can be used on various metal forms, including metal sheets, tubes, and other shapes. However, the specific types of metal forms that can be welded depend on the capabilities of the robotic spot welding system and the welding process parameters.
  • Precision and Consistency: Robotic spot welding machines are equipped with controls that allow for precise adjustments to the welding parameters, ensuring consistent quality and reducing the risk of defects. Robots also ensure that the welding process is accurate and consistent, even with complex shapes and large production volumes.
  • Improved Safety: Robotic spot welding eliminates the need for manual welding, which can be hazardous for workers. By using robots, manufacturers can improve safety in the workplace while maintaining high productivity levels.

Disadvantages of Spot Welding:

  • Limited joint access: Robotic spot welding requires access to both sides of the metal pieces being welded, which can be challenging in some applications, limiting the ability to weld complex shapes or parts.
  • Size limitations: Size limitations: Robotic spot welding is generally suitable for welding metal sheets up to 5mm thick. For thicker metal sheets, a different welding process may be more appropriate.
  • Equipment: Robotic spot welding requires specialized equipment, which can be expensive and complex to maintain. However, those costs can be offset by the speed and efficiency of the process.
  • Weld strength: The strength of a spot weld is limited by the size of the weld, making it essential to consider the design of the metal sheets being welded carefully.


How Does Spot Welding Work

How Does Robotic Spot Welding Work

To prepare for robotic spot welding, it is important to have all necessary equipment, including spot welders, electrode caps, weld tips, and protective gear. The metal components to be welded should be thoroughly cleaned to remove any dirt, oil, or other contaminants that could interfere with the welding process. This can be accomplished using a degreaser, wire brush, or sandpaper.

Before welding, it is crucial to inspect the metal to ensure it is free of cracks, dents, or other defects that could affect the quality of the weld. If any defects are present, they should be repaired or removed before welding. Proper electrode selection is also important, as electrodes must be the correct size and material for a successful weld.

1. Setting the Machine 

First, select the appropriate current, time, and pressure settings for the metal pieces being welded to set up the spot welding robot. Determine the component’s thickness and material type and consult the manufacturer’s specifications for the recommended settings. Adjust the welding program controls to match those specifications.

The current setting determines the amount of electrical energy used for the welding process, while the time setting determines the duration of the weld. The pressure setting determines the force applied to the metal during welding. Correct settings are crucial to achieving consistent and high-quality welds.

Programming the robotic system to apply the correct settings is critical to ensure that the welding process produces consistent and high-quality results. Following these steps, the robotic spot welding machine can be set up for optimal performance, achieving efficient and effective spot welds.

2. Clamping 

Proper clamping is crucial for a successful robotic spot welding process. It ensures that the components are aligned and overlapping correctly, which is necessary for a strong and reliable weld. In robotic spot welding, the pieces are usually clamped between the electrodes of the welding machine.

The clamping pressure is adjustable and should be set according to the thickness and type of material being welded. Too much pressure can cause deformations or damage the piece, while too little pressure can result in a weak or failed weld. Therefore, the proper clamping pressure is essential to achieve consistent and high-quality results in robotic spot welding processes.

3. Inspection 

Inspect the weld to ensure it is solid and free of defects. It’s important to regularly inspect the spot welds to ensure they are strong and reliable and to identify and address any issues as soon as they arise.

The type and frequency of inspection will depend on the application and the specifications for the welded parts. Here are the steps for inspecting a spot weld:

  • Visual inspection
  • Tensile test
  • X-ray inspection
  • Ultrasonic inspection
  • Microscopic inspection

4. Welding 

To begin the welding process, the robotic system is programmed to position the pieces accurately, and the welding machine is turned on. The operator then adjusts the current, time, and pressure settings according to the specifications of the material being welded. 

Once the settings are adjusted, the robotic system applies pressure to the components, and the welding machine passes an electric current through the overlapping parts. This causes the metal to fuse, creating a strong and permanent bond.

5. Cooling 

After the welding process is complete, the components are allowed to cool and solidify. Proper cooling is important because it helps control the solidification rate and minimize any distortions in the final piece.

If the metal cools too quickly, it may become brittle and susceptible to cracking, while if it cools too slowly, it may deform. Several factors influence the cooling process, such as the size of the weld, the type of metal being welded, and the cooling rate.

Some welding machines in robotic spot welding are equipped with cooling fans or water-cooling systems to help control the cooling rate. These cooling systems help ensure the material is cooled correctly, minimizing distortions and ensuring the final product meets the required specifications.

Laser Cutting

A Guide for Choosing Laser, Water, or Plasma for Your Next Metal Cutting Project

Before you can begin to think about your latest metal project, your primary focus of attention may be on which way to cut the metal parts from the sheets of metal stock you have chosen for this metal cutting project.

In this post, let’s examine laser, waterjet, or plasma arc cutting as your choices at hand. Then let’s further enhance your metal-cutting project by putting you in touch with a metal-cutting project leader at Glenn Metalcraft, your one-stop metal-cutting project service provider.

Laser Cutting for Your Metal Cutting Project

Let’s take a look at what laser cutting consists of to gain a better understanding. First, LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. When you laser cut the pieces for your metal cutting project, you use a thermal-based fabrication method to cut, etch, and otherwise prepare the needed components for your metal cutting project.

That might be a bit of a mouth full, but in short, the produced laser beam in our shop is guided through CNC equipment, focused through various optics, and then used to slice through the sheets of metal stock, producing your needed metal parts and pieces.

Ideal Metals to Cut With Laser Cutting

Some metals have characteristics such as being light-reflective or extremely heat conductive. Copper and aluminum are examples of such metals and require cutting from sources other than lasers. Brass, steel, nickel, and tungsten are ideal for laser-cutting technology.

Pros of Laser Cutting

  • High precision: Laser cutting machines can cut metal parts with a high degree of precision, resulting in clean edges and minimal distortion.
  • Fast cutting speeds: Lasers can cut metal quickly, making them an efficient choice for high-volume production runs.
  • Versatility: Laser cutting can be used on a wide range of metal materials, including steel, aluminum, and titanium.

Cons of Laser Cutting

As with any thermal process, laser cutting can come with its own set of drawbacks, such as;

  • Limited thickness capacity: Laser cutting is not effective for cutting metal thicker than about 1 inch.
  • Heat-affected zone: Laser cutting generates heat which can affect the properties of the metal, such as changing the hardness or temper.
  • Warping or deformation: Laser cutting can cause warping or deformation of the metal, especially in thicker or more heat-sensitive materials. 

Waterjet Cutting for Your Metal Cutting Project

Waterjet Cutting Machine for metal cutting project

Waterjet cutting technology is a bit easier to explain than laser-cutting technology. In waterjet cutting, water is directed at a very high velocity through specialized jets to produce an effective and clean cut of your metal sheet stock. Sometimes, an abrasive substance is added to the water for use on types of harder alloys to enhance its cutting ability.

Similar to how water eroded and created the Grand Canyon over centuries, waterjet cutting employs the same technique but on a smaller and much more accelerated scale. Utilizing a high-pressure pump, waterjet cutting creates a fluid stream of up to 94,000 PSI. In perspective, a waterjet cutter is 80 times more powerful than a fire hose!

Ideal Metals to Cut With Waterjet Cutting

Without any added abrasive, waterjet cutting alone is ideal for softer materials like plastics, cement boards, and foam. To get the desired results from waterjet cutting for your metal cutting project, a special jeweled orifice is used in conjunction with garnet abrasives that exit the nozzle up to four times faster than the speed of sound. This allows metal materials up to one foot in thickness to be cut.

Pros of Waterjet Cutting

  • This is a cold-cutting method that produces ZERO heat-affected zones.
  • Omni-directional flexibility. You can cut in any direction, not just straight down.
  • Cutting so precisely with water is possible that no secondary finishing is required.
  • This process is safe and environmentally friendly.

Waterjet cutting is ideal for cutting, shaping, and reaming metal parts for aerospace and mining applications.

Cons of Waterjet Cutting

  • It may not be suitable for cutting materials thicker than about 6 inches.
  • Although extremely precise, waterjet cutting does not match the tight tolerances that some other cutting methods, such as laser cutting, can achieve.
  • Some materials, such as tempered or heat-treated steels, can be difficult or impossible to cut with a waterjet due to their hardness or the heat-affected zone created by previously employed cutting processes on the same piece.

Plasma Cutting for Your Metal Cutting Project

Plasmacutting at Work

So far, we have used amplified light sources and high-pressure water to cut the pieces of your metal cutting project. Now it’s going to get a bit more scientifically advanced. We all know the three states of matter, solid, liquid, and gas. Basic middle school science, right?

Plasma is sometimes referred to as the fourth state of matter. When certain gasses are superheated, they become ionized. This makes the gas electrically conductive by turning the gas into plasma. 

Plasma cutters can use oxygen, nitrogen, argon, or even compressed air as their gas to heat via an arc produced by the cutting machine. As the gas and arc combine at the orifice point, all is converted to plasma. 

Ideal Metals to Cut With Plasma Cutting

Any metal that is a good conductor of electricity is ideal for a plasma cutter.

Those metals are;

  • Aluminum
  • Brass
  • Carbon steel
  • Copper
  • Mild Steel
  • Stainless Steel
  • Expanded Steel

Sheet metal 1-2 mm and up to 1-2 inches thick are also ideal.

Now the Pros and Cons of plasma cutting.

Pros of Plasma Cutting

  • Plasma cutting is a fast cutting method that can be used to quickly and efficiently cut a wide range of materials.
  • It can provide high cutting accuracy from metal to non-metals.
  • It is a versatile cutting method and can be applied to a wide range of industries.

Cons of Plasma Cutting

  • Plasma cutting is less precise than other cutting methods, such as laser cutting or waterjet cutting, and may not be suitable for projects that require tight tolerances.
  • The intense heat generated by plasma cutting can cause warping or distortion in some materials, particularly thin or delicate materials.
  • Plasma cutting is typically limited to cutting materials no thicker than 1-2 inches, depending on the specific equipment and settings used.

The Next Level in Your Metal Cutting Project

Now that you have seen the differences between laser, waterjet, and plasma cutting and the pros and cons of each, let’s take your metal cutting project to the next level!

That being said, contact your one-stop shop for all your metal cutting project needs – Glenn Metalcraft.

Laser Cutting

Materials Suitable for Laser Cutting – A Comprehensive Guide

Laser cutting is an incredibly versatile technology that produces intricate and precise pieces of work from various materials. It’s an extremely convenient tool with many applications, as lasers can easily be used on many kinds of materials. This comprehensive guide will discuss the different types of laser cutting, which materials you should avoid, and which materials are suitable for laser cutting and engraving.

We will also provide some application ideas for each. So, if you’re looking for a deeper dive into materials suitable for laser cutting, you’ve come to the right place.


An Overview of Laser Cutting

Laser Cutting Machine

Laser cutting is an advanced technology for precision cutting or engraving materials. It uses a laser beam to cut or etch the desired shape into a material. Laser cutters use a concentrated beam of light created by a high-powered laser and focus on the material with extreme precision. Some common applications for laser cutting include industrial fabrication projects such as robotics components, furniture manufacturing, molds and dies fabrication, vehicle components, and tooling production.

There are four main types of laser cutting; fusion, vaporization, fracture-controlled, and laser flame. Fusion cutting involves melting the material so a fine beam can cut it, while vaporization cuts by quickly evaporating sections of the material before the beam melts the rest away. Fracture-controlled cutting works by creating high-stress points in the material and breaking it with minimal debris or heat produced. Lastly, laser flame works similarly to oxyfuel but produces no chemicals during the process.

The advantages of laser cutting are numerous. It is a highly accurate and cost-effective way of producing shapes from many materials. It is faster than traditional cutting methods and has clean edges with little to no waste. Laser cutting creates the smallest heat-affected zone (HAZ) of all the thermal cutting methods because of its fine beam. 

Laser cutting is an efficient and environmentally friendly process for cutting metal. The laser beam used in laser cutting is extremely precise, resulting in minimal material waste as opposed to other processes. This also reduces the amount of hazardous materials released into the environment, making laser cutting a much greener choice. 


Materials Suitable for Laser Cutting or Engraving by Laser

Materials Suitable for Laser Cutting

This technology enables materials such as metal, stone, glass, and even materials that are difficult to cut or engrave, like titanium, to be accurately cut with a high degree of efficiency.

In addition, laser cutting is suitable for synthetic materials such as polyethylene, polypropylene and polystyrene, and some other non-metallic materials such as paper, cardstock and cork.

Some materials may need pre-treatment prior to cutting due to their reflective properties; for example, magnesium or aluminum should be avoided because they reflect laser beams rather than absorb them. Such materials require additional material coatings in order to ensure an effective cutting process. Alternatively, fiber laser cutting, using fiber optic cable to transmit the laser beam to the reflective surface, is another way around this issue.

When looking for materials suitable for laser cutting or engraving with a laser cutter, it is essential to know the material specifications of your finished piece. Metallic materials such as stainless steel and aluminum are excellent for laser cutting, as they have a high melting point and can withstand the high temperatures of the laser beam. Other metals like brass and copper can also be used for laser cutting but are more likely to warp or deform. 


Application Ideas

Laser cutting is an innovative precision technology used in a wide variety of industries and applications. This precision process can create intricate shapes with accuracy down to 0.002 inches, making it ideal for use in aerospace, tooling, manufacturing, medical device, and electronics production. This process can provide precision not possible with traditional methods like sawing or punching as well as reducing material waste and cost compared to other processes. 

Etching is another application for laser cutting. Etching can create intricate designs on a wide range of materials, from stainless steel to glass and plastic. Laser cutters allow you to precisely etch designs onto various materials for decorative and practical purposes.

You can use laser cutters for welding if the beam power is strong enough to melt the materials during the cut. This process allows for flexible production and greater versatility in completing a job. An even better option is combining a laser cutter with a welding head, which can further maximize precision to perform welding tasks successfully. This combination also enables industry professionals to complete welding objectives quickly, cost-effectively, and efficiently.

Laser marking is another application of laser cutters. It allows you to permanently mark text or symbols onto many materials, such as metals and plastics. Laser marking is often used in industrial settings to tag products or components with branding or logos.

Finally, drilling is possible with certain types of laser cutters. They can cut tiny holes into metal and other materials quickly and accurately, making them ideal for tasks where precision is essential such as in the manufacturing of electronic components.

CNC Machining

Metal Prototype Machining and Other Options

Simply put, prototype machining produces a small number of parts before generating a bigger batch. Most businesses opt for prototype machining for appearance and testing purposes.

The former checks how the part will look after production, while the latter is more concerned about the performance of the part and whether it will perform its intended purpose.

To get a reliable turnaround, you need precision capabilities. Getting a dedicated business to handle such precision is no walk in the park because talk is cheap. At Glenn Metalcraft Inc., we provide unmatched prototype designs that give you a high ROI.

What is a prototype? 

A prototype is an early version of a product that is created to test its concept and performance. Ideally, you can’t produce a part in large quantities before testing it, and the best way to do it is through prototyping.

A prototype allows you to evaluate a product and improve its accuracy, quality, and design. Prototypes often fail during testing, and it’s usually a good gesture because designers can detect defects early, correct them, and produce a reliable final product.

When are prototypes used? 

Prototypes come in handy during the design process. Industrial engineers can test products through prototypes before they can begin mass production. Additionally, prototyping can be used to evaluate an existing design or product and improve its precision.

Most of the time, theoretical tests don’t provide real-life solutions. As a business, the only way to stand out and serve your clients beyond expectations is to ensure your product is well-tested in the design stage. 

Through prototyping, errors in the final product are not passed directly to consumers. The process is also cost-effective for businesses.

The prototyping process

The prototype machining process provides quick feedback to the engineers on the performance of the design. Through feedback, the engineers can go back to the drawing table, improve the prototype, and have an effective final product.

However, the prototyping process has some crucial steps to obtaining optimum performance. They include:

Design review

The first step engineers undertake is to review the design using a 3D CAD system in molding. At this stage, engineers can get an insight into the most efficient design features and make adjustments before the model is produced.

Engineers can plan and ensure that every prototype can be produced efficiently on a large scale because some prototypes are difficult for mass production.

Creating a 3d model

Creative company professional digital engineer modeling 3D mesh while improving geometry. Asset creator optimising polygon count while using CAD

After engineers have correctly mapped the design review process, the next step is to create a 3D model. The molded prototype is then sent to a machine shop for production using a CAM program.

Engineering the prototype

The last step is to engineer the prototype. CNC prototyping can be used in this process; however, it’s not cost-effective compared to 3D printing, especially if you need to cut expenses in the prototyping stage.

The design roars to life after the prototype is finally produced. After that, the prototype can be put into mass production.

Benefits of prototyping

Different prototype parts play different roles, all in harmony to have an efficient final product. A lot goes on during the product development stages, and we can’t truly appreciate prototyping without listing its benefits. They include:

  1. You get to receive feedback from end users, such as customers
  2. You get to discover design problems early and correct them.
  3. You get a precise estimate of the production cost
  4. You’re able to test and determine if the product is durable
  5. You can improve the product
  6. You can raise funds and find investors because you have a working prototype to demonstrate.

What are the advantages of metal prototypes? 

Metal Prototype Machining

Metal prototypes are made using metal manufacturing techniques such as CNC machining, sheet metal forming, and casting. Although you can use plastics for prototypes, metal is preferred because it closely mimics the final products.

Some of the advantages of using metal prototypes include the following:

  • You get better functional and mechanical performance
  • You get precise, accurate testing
  • You get better aesthetics
  • You get a higher chance of convincing an investor
  • It’s easier to move to the next phase, which is the production

What methods are available for making metal prototypes?

The available methods for making metal prototypes differ in mechanical results achieved, costs incurred, and the time taken in production. To get a better glimpse, we will take a look at some of the methods.

Metal machining

CNC machining uses instructions from a computer to cut a metal block. The method is relatively affordable because you can make duplicates easily or share the design with other parties. However, the subtractive nature of the prototype machining process leads to material wastage.

3D printing

3D printing, just like CNC machining, uses design input from a computer. The 3D-printed prototypes stand out from the rest because of their complex features, especially in the internal sections. In addition, you also get the design at a low cost, although the surface finish may not be impressive.

Metal casting

During metal casting, you pour hot liquid metal inside a mold. When the mold cools down, it becomes a part. Metal casting parts are solid and high quality, but quality comes at a price. You require specialist equipment, which is quite expensive.
