When and Why Use Photo Chemical Etching to make your super thin shims?

Photo chemical machining produces burr-free metal shims with none of the deformation that other manufacturing processes can cause. It is a fast, efficient, cost-effective alternative to stamping, punching, laser cutting, and other production methods.

There are essentially no limits to the designs we can work with. No matter how simple or complex your design, we can use chemical etching to produce precision metal shims that perfectly match your specifications. Whether you need a half dozen parts or 100,000, photo chemical machining can produce metal shims with perfect precision and repeatability from the first piece to the last.

We also provide in-house forming, as well as additional secondary services such as plating and heat treating, to add further value to our products. We offer some of the industry’s fastest lead times, low, one time tooling costs, and one of a kind, personalized service. Prototyping services are also available.
