What is Sheet Metal Prototyping?

A prototype in sheet metal fabrication is a physical model that allows designers to assess and evaluate the functionality and appearance of a part before mass production. Whether crafting functional prototypes or not, sheet metal offers a versatile medium for testing designs.

Not only does having a prototype attract more investor interest, showcasing the durability and aesthetics of the design, but transitioning from a sheet metal prototype to the final product is often more seamless than moving from a plastic prototype to a metal component.

  • Standard lead time: 7 business days, ensuring swift sheet metal rapid prototyping service for clients.
  • Sheet thickness: Ranges from 0.024” to 0.250”, with flexibility to accommodate requests for thicker or thinner gauges.
  • Tolerances for single planes or flat parts: Precision maintained at +/- 0.010” on edge-to-edge, edge-to-hole, and hole-to-hole features, as well as +/- 0.010” on bend-to-edge/hole features.
  • Tolerances for multi-planed bent parts: Stand at +/- 0.030” for hole to hole/edge, edge to edge, and over-formed parts, and +/- 1 degree for bend angles.

Moreover, our welding capabilities cover welded edges and seams, weldments, and assemblies, providing a comprehensive suite of services in sheet metal fabrication.


Sheet Metal Fabrication Processes

Sheet metal fabrication involves various processes to transform flat metal sheets into finished products. Our key processes include:


Using a die with the desired part shape to press sheet metal involves processes like punching, blanking, bending, drawing, and embossing.

Laser Cutting

Using a laser beam to precisely cut through metal sheets allows for intricate designs and accurate shapes.

CNC Punching

Employing a computer-controlled punching press to create holes and shapes in metal sheets.


Joins metal pieces together using heat and pressure to create strong and durable connections.

Shaping metal sheets by applying force, often using a press brake, to achieve desired angles and forms.

Assembly & Kitting

Putting together fabricated components and organizing them into kits for efficient use in the manufacturing process.
