Sheet Metal Prototype Fabrication: The Ultimate Guide

Before starting any sheet metal prototype fabrication process, read this guide.

It covers all the vital aspects about fabricating sheet metals.

Take a look:

What Is Sheet Metal Prototype Fabrication?

This is a production process that focuses on turning metal stock into usable parts. Sheet metals used are not flat as perceived.

They have a thickness of 0.006-0.25 inches. Metals that are thinner than 0.006 are called ‘foils or leaf metals’ while those thicker than 0.25 are ‘metal plates.’

Generally, prototypes verify the design intent for production.

So, by fabricating sheet metal prototypes, you can easily tell if the process is worth it or not.

Benefits Of Fabricating Sheet Metal Prototype Parts

i. Physical product– you get the opportunity to hold a tangible miniature of the product in the initial stages of the production process.

It gives you the opportunity to review the design, the methodology and also able to get feedback from the customer or the production team

ii. A functional prototype allows fit, form, and functional testing

  • Fit– this is the first test of sheet metal formed parts at the prototype stage that clearly shows errors such as the gap, misalignment, overlaps, etc.

Once the errors have been identified they are reviewed to establish whether they occurred during the design process or the production process.

If the prototype has errors, another prototype has to be made to correct the errors made before making the final product.

  • Form– this is all about the aesthetic value of the prototype. How it looks in terms of the size, weight, color, and finished look. We review whether or not change is required.
  • Function– some prototypes are not functional its okay if they serve the purpose. However, functionality is the main reason we make prototypes to ensure they perform as intended before going ahead and making the end product.

The prototype is tested against all the design calculations and parameters such as strength, stress, impact, performance, reliability, and any other thing that is design-related.

iii. They help you get rid of guesswork in the manufacturing industry.

You are able to see the product and test the errors before creating the end product.

They may be costly but imagine going ahead and making the actual product and then you realize it has a whole batch of errors and you have to re-do the entire process.

You repeat the same process then God forbid you make a mistake again. You will run mad! Save yourself from all this stress.

Make prototypes first they may cost you but not as much as re-doing an already done project. Fix a whole lest you will build an entire wall.

Factors Determining Cost Of Sheet Metal Prototype Fabrication

Sheet metal prototype fabrication

Sheet metal prototype fabrication

Consider the following factors to reduce the price of sheet metal prototype fabrication:

i. Raw materials– The materials used to manufacture your parts affect the overall price. Materials like magnesium are less expensive than stainless steel.

The thickness of the material also affects the price of the prototype.

That said pick materials that have properties that will fulfill your project’s demand. Do not compromise on the quality because of the price.

Remember cheap is always expensive. Ensure the raw materials are quality and functional.

ii. The complexity of the design- while we encourage creativity in the production industry.

You will pay more for a complex design as opposed to a simple one.

A design that is simpler and requires fewer cuts, mills, bends, etc. is going to cost the least.

A part that requires many cuts or several bends is going to cost more time on each machine and we all know time is money.

The design may cost more in both the design and prototyping phases.

Accuracy goes hand in hand with the design.

If accuracy is a not major factor the machine can be set to handle the process quicker.

But if it is a factor and even the smallest details are necessary, you will pay for the machine to work at a slower pace to capture all the nitty-gritty.

iii. Finishing – a prototype that needs no finishing will be goods to go after getting out of the manufacturing machine.

But most parts of the prototype need smoothening, or sanding of edges.

After the assembly process, they need extra polishing and painting according to your needs.

iv. Quantity– the more prototype samples required the higher the cost.

However, the cost per item reduces once you order more especially if the design is the same hence we don’t have to set up the machine again.

This will reduce the cost of labor hence reducing the price.

Of course, other factors such as type of machine and cost of labor will also play an important role here.

Prototype Sheet Metal Fabrication Process

We begin the process with a flat piece of metal then we convert it into a product. The process involves 3 different steps:

Cutting sheet metal

Cutting sheet metal

i. Cutting process– here the sheet metal is operated to create cuts using special pieces of machinery. We use plasma cutters, CNC laser cutters, and water jet cutters.

ii. Deformation process– in this process the shape of the sheet metal is converted by either stretching or drawing. We use press brakes and metal stamping process.

Press brakes makes it possible to bend sheet metals into the preferred shape, design, or angle you want. Metal stamping on the other hand allows you to perform specific tasks like embossing, hemming, and drawing.

iii. Assembly– this is the third part of the process. Here different sheet metals are joined together by the use of welding or fasteners.

Welding is the most popular method as there are different methods including plasma arc welding, electron beam and laser welding, etc

Example; if you want to fabricate and assemble two 45 degrees angle brackets, you need to create important features like holes first on the flat sheet metal parts using a laser cutter, water jet cutter, or plasma cutter.

Then place these sheets of metal between the punch and die of the press brake and bend until you the 45 degrees. In the end, fasten or weld the parts together to form the desired shape of the metal fabrication prototype needed.

Engineering Materials For Sheet Metal Prototype Fabrication

Almost all engineering materials are used in the form of sheets. Some of the metals include; aluminum, stainless steel, copper, and magnesium

Choose metal according to the end use of the product bearing in mind different metals have different strengths and abilities. They include:

i. Aluminum– pros; Its lightweight, corrosion-resistant, electrical and thermal conductivity, it’s recyclable, it’s odorless and impermeable, reflective and ductile, versatile and flexible.

cons- has a lengthy and expensive welding process. it’s not as strong as other metals i.e. steel

ii. Stainless steel-Pros; It has superior durability, corrosion resistance, is recyclable, readily available, easy to clean and maintain, economical, and has excellent mechanical properties.

Cons; Tends to be more expensive than alternative metals, it’s difficult to weld and fabricate, and its rings can bend after some time.

iii. Copper– is a good electrical conductor for wiring; it is not reactive so can be made into water pipes

Cons- it corrodes easily and is costly

iv. Magnesium metal– pros; they offer high strength and durability, and they are lightweight.

Magnesium metal

Cons- it’s highly flammable and combustible. There is a high risk of fire and explosion during and after the fabrication process.
