Tech Met has been dedicated to providing responsive, competent and high quality chemical milling services on fabricated components since 1988. Work on high temperature, titanium and ferrous alloys have been the prime focus, primarily serving the aerospace engine fabricating market in the Eastern US.
With a staff of 20 technicians, engineers and support personnel, we conduct part preparation, masking, and chem-mill processing in our 15,000 square foot facility located in Western Pennsylvania.  We handle parts up to 10,000# and 20 feet in length in a variety of forms- forgings, sheet, tubing and fabricated sheet metal components in both short run prototype or series production volumes.In addition to conducting conventional chem-milling to print and specification requirements, we conduct a variety of related processes including pickling, passivation, and HIP can removal.We have been involved in a number of process development efforts for special etching, chem-milling, and surface preparation applications and hold a patent for surface texturing orthopedic implants using chemical milling.If you have a requirement for milling parts to a print or specification, or have an idea that chemical milling can benefit your product or process, we can probably help.Tech Met performs chemical milling primarily on titanium, hi-temp and ferrous alloy components, and some aluminum alloys. Alloys such as tantalum, copper, and magnesiumare also processed.Chemical milling can be done from all surfaces or selectively via masking. Milling is done to print or specification.Typical applications of chemical milling include Inconel jet engine mixer components, titanium exhaust system cowlings, forgings (titanium,steel, or hi-temp), engine combustion cases, and thin wall tubing.Tech Met does some smaller aluminum components in typical aerospace alloys
