Sheet Metal Prototyping: Custom Parts & Design Services USA

Sheet metal prototyping provides an effective method for quickly creating a working metal prototype from a digital design before progressing to full-scale production. It enables engineers, product designers, startups, and manufacturers to test a component's shape, size, fit, function, and manufacturability early in the design process.

Professional sheet metal prototyping can help minimize development risks and enhance the final design for products that call upon metal enclosures, brackets, panels, covers, frames, housings, or other formed parts.

CAD Verse Engineering is a company that provides engineering expertise, 3D CAD design, prototype and manufacturing-focused design services to aid in the transformation of concept into physical products.

What Is Sheet Metal Prototyping?

Sheet metal prototyping is the manufacture of a physical model from a sheet metal design that is used to test the design prior to larger-scale production. Typically, a CAD model is created as a digital representation. The design is then reviewed for its dimensions, materials, bends, features, and manufacturability prior to prototype production.

Commonly Used Examples Of Sheet Metal Prototype Applications

Sheet metal prototypes can be created for numerous applications such as:

• Product enclosures
• Equipment housings
• Brackets and mounting parts
• Control panels
• Protective covers
• Structural parts and frames
• Industrial components
• Custom metal parts

The specific technique used will vary according to the geometry, material, size, quantity, and the use of the part.

Why Is Sheet Metal Prototyping Important?

Perform A Test Of The Design Before Production

Some of the greatest benefits of prototyping are that it allows you to test a design before going into full production. A physical prototype can be used to spot dimension, fit, assembly, accessibility, clearance, and overall function problems.

Reduce Manufacturing Risk

It is easier and cheaper to fix design problems in the prototype stage than once production has started. A prototype test can be used to test the design and give indications to make it easier to manufacture before production.

Faster Product Development

A product-development process can be iterative with the use of the sheet metal prototyping process. The engineer can develop a CAD design, then make a prototype, check it, modify as needed, and make an enhanced version. This method is useful to accelerate the transfer of the product from idea to production.

Sheet Metal Design For Manufacturing

The first step to a good sheet metal prototype is to have a good design.

CAD Modeling

• It may start from a sketch, drawing, reference image, dimensions, or a pre-existing CAD file.
• The idea can then be formalised into a detailed 3D CAD model.

Design Considerations

When designing a professional sheet metal part, you might need to take into consideration:

• Material thickness
• Bend locations
• Bend radius
• Overall dimensions
• Holes and cutouts
• Mounting features
• Assembly requirements
• Manufacturing method
• Tolerances

These factors should be taken into account early on to develop a prototype that is easily produced.

Materials Used For Sheet Metal Prototypes

The material used will be determined by the specific use and desired properties of the final product.

Common considerations include:

##### Aluminum

If lightweight construction and corrosion resistance are significant factors, aluminum may be beneficial.

##### Stainless Steel

If durability and corrosion resistance are critical, stainless steel might be used.

##### Mild Steel

• For some structural and general-purpose applications, mild steel can be used when strength and cost are critical.
• The choice of materials should be according to the specific needs of the parts, rather than just appearance.

How To Create Prototypes Using Sheet Metal

A professional workflow can be used to move a project from an initial idea to a physical prototype.

Step 1: Share Your Design

Use a sketch, drawing, dimensions, reference image, or existing CAD model.

Step 2: Develop the CAD Model

The design is translated and/or simplified into a reviewable detailed 3D CAD model.

Step 3: Review and Optimize

The design can be checked to see that it is dimensioned, bent, and constructed of adequate thickness with clearances and assembly requirements, and also for manufacturing.

Step 4: Make the Prototype:

The approved design is used to produce the physical sheet metal prototype using an appropriate manufacturing process.

Step 5: Test the Physical Part

The prototype can be tested for fit, size, function, look, etc., for the project's needs.

Step 6: Improve the Design

If changes are needed, then the CAD design can be modified prior to the next prototype or larger production.

Product Development: Custom Sheet Metal Prototyping

Sheet metal prototypes have a lot of value in the development of a new product. A prototype can be used by designers and engineers to test an enclosure for a specific product, a mounting system, a metal structural part, or any other metal part before it is actually produced.

This can be beneficial for startups as well as established manufacturers for faster iterations in design and also for spotting any future manufacturing problems early on. CAD Verse Engineering is an engineering-centric workflow that integrates 3D CAD design, prototyping, Design for Manufacturing, and product development support.

Frequently Asked Questions About Sheet Metal Prototyping

What is sheet metal prototyping used for? Sheet metal prototyping provides a tangible representation of metal parts to test the design, fit, size, function, and manufacture of the part before going into full production.

Is it possible to make a sheet metal prototype from a CAD model? Yes. A CAD file can also be used as a starting point for reviewing and developing a prototype of the sheet metal product, if the information for the project is included in the file.

Is it possible to design a prototype of a part made of sheet metal? Yes. Custom prototypes can be created according to the drawing, size, material, and processing requirements of the project.

What is the need for CAD before sheet metal prototyping? The design can then be created and evaluated virtually using 3D CAD before the part is manufactured. This will facilitate the discovery and resolution of design problems earlier.

Will sheet metal prototype be used for new products? Yes. It can be helpful in product development, as a physical prototype can be tested by designers and engineers before a greater number of products are produced.
