Prototek Sheet Metal Manufacturing began in 1987 as a family owned and operated business as a supplier of quick turn precision sheet metal and machined products for the prototype markets. Today we are still a family owned and operated business, and many of our employees are from our original team. We have since launched into rapid prototyping of precision machining production as well. Our quality and turn times continue to be among the best in the industry. Serving industries such as robotics, semi-conductor, telecommunications, military, pharmaceutical, medical, computer technologies and aeronautics. Prototek’s capabilities include punching and cutting of sheet metal from 0.010″ – 0.375″ thick, forming, installing hardware, welding, machining, plating, painting, powder coating, silk screening, stamping, part marking, and assembly all under a single roof to help save our customers time and money on their finished parts while ensuring Prototek’s trademark quality! At Prototek, our punch press, 4000 watt laser, and two LC-C1 Punch/Laser combination cells run 24/7 which translates to faster turn times for our customers. Our highly qualified staff of employees take measures to ensure parts flow through our manufacturing process quickly and efficiently. Each operation goes through an in-process inspection to ensure the highest level of quality

We also keep a very large stock of well over $10,000 in PEM hardware, as turn times have always been our niche, so we take every step necessary to guarantee our customers get their parts as quickly as possible.
