The first stop when searching for precision prototyping is the search engines. Search engines such as Google are today’s primary source of information for products and services across the globe. With the internet increasing taking center-stage in the global trade of products and services, this resource should be the first destination if in need of any products or services. You get in-depth information and reviews to aid your decision making.

Importantly, on the subject matter of prototyping services, the internet can help you find a services provider who will make products in the type of materials and sizes you need. Keep in mind that prototyping firms specialize in different kinds of prototyping. Some firms focus on prototyping large products while others focus on retyping smaller products. As such, you would not want to contract a company that prototypes computer products to prototype your engine or vice versa.

Precision sheet metal fabrication is the production of products using materials such as steel, copper, aluminum, titanium, spring steel, stainless steel, and brass. High-tech companies such as defense, automotive, aerospace, and medical companies usually design the products. The design files are thereafter sent to the prototyping companies, where the files are fed into some of the world’s state-of-art fabrication and manufacturing equipment. The process of fabrication involves a myriad of processes such as forming, bending, cutting, assembling, and finishing.

Cutting sheet metal into precise sizes is done using laser cutting, shearing, or sawing. Shearing has been the standard method of cutting. However, it is being quickly replaced by lasering. Laser and plasma cutting offers fabricators a cleaner cut. Importantly, this new method can cut through a thin and thick (.500 inch materials) far more efficiently and quickly. As such, sheet metal fabrication companies that have lasering capabilities tend to have a shorter turnaround.

Stamping is used to form the metal. Forming is used in materials meant to be bent and assembled. Some of the fabrication processes used in forming a sheet metal material include but are not limited to blanking, embossing, punching, and deep drawing. The processes are typically achieved using mechanical or hydraulic presses. The best press of these two types of presses is dependent on the application and specific prototype.

Bending is characteristically a flexible process that allows the fabrication of different shapes using press brakes and hammering. For precision sheet metal fabrication, they use complex mathematical formulas to determine the right bend allowance for stretching and compression of the materials used. Typically, companies will reverse engineer using CAD programs to determine the right bend allowance much faster.

When all the components are completed, they are thereafter assembled. This is done using methods such as welding, which is done by highly skilled welders. However, programmable spot welders are becoming increasingly more common and popular. The robots make welding and the overall manufacturing process much safer, more cost-effective, and very efficient. In some cases, thread fastening and riveting are also used in the assembly process.

Some prototype products need additional finishing. The finishing may include sandblasting and powder coating or painting. Powder coating is a metal coating that is applied to a metal component while in a solid powder form and not a liquid. After application, the coating is cured in high temperature, allowing the powder material to bind to the metal component. The result is an exceptionally hard and durable skin.

At the end of the process, the finished products are inspected and examined and delivered to the customer.
