Parts
Tech-Etch specializes in the manufacture of light gauge metal parts from .0005" thick and up. The photo etching process (also called photo chemical etching and photo chemical milling) allows us to produce intricate metal components with close tolerances that are impossible to duplicate by other production methods. Photo etching eliminates the cost of hard tooling, improves design flexibility, and shortens lead times while eliminating burring and stress problems. Tech-Etch is setting industry standards for the manufacture of encoders, masks, filters, lead frames, Battery Grids, flat springs, strain gauges, laminations, MicroEtch Screens, chip carriers, step covers, Fuel Cell Plates, heat sinks, shutter blades, electron grids, fluidic circuit plates, reticles, drive bands, haptics, and shims. Titanium etching, Tungsten etching and etching of other extremely corrosion resistant materials, such as Nitinol, Elgiloy and Molybdenum, enable Tech-Etch to produce complex parts for medical tools and implants. Copper Alloys, Beryllium Copper, Stainless Steels, Aluminum, Nickel and Nickel Alloys, Silver, Spring Steels, and Polyimide Film are also etched.
Forming and Finishing
Tech-Etch manufactures formed parts by combining photoetching, used for blanking, with inexpensive or universal tooling, used for forming. This method produces burr-free parts in intricate and complex designs and shapes. It also makes it possible to prove your design in preproduction quantities without having to commit to expensive, progressive die tooling. Visit our Flat Design Guide and Formed Design Guide for complete specifications.Tech-Etch has a full in-house plating and mechanical finishing facility. This includes Gold, Nickel, Electroless Nickel, Copper, Tin, and Tin-lead plating, plus solder hot oil reflow. Electropolishing, surface polishing, and vibratory tumbling are part of the finishing department. Tech-Etch's masking skills can be used for selective plating.
Laser Cutting
The Tech-Etch Laser Machining Center provides additional capabilities and greater tolerance control for thicker materials. A 2.5 KW Mitsubishi CO2 Pulse Laser can cut a wide variety of materials in various thicknesses, and is particularly suited to prototype applications. The High-Peak Pulse feature enables us to provide dross free cutting of all metals, including the reflective metals such as Copper, Brass and Aluminum. By combining laser cutting with etching and forming, Tech-Etch is able to produce thick parts with grooves or pockets that extend only partly through the material.
