January 9, 2019 - Custom fabricated photo etched titanium fuel cell plates, micro-channel plates, and heat exchangers with deep, precise burr-free channels are being introduced by Photofabrication Engineering Inc., Milford, Massachusetts.
PEI Photo Etched Titanium Plates can be produced in sizes up to 28 in. by 58 in. and 0.125 in. thick with burr-free channels and precise depths. Chemically machining all channel depths to ±0.001 in. simultaneously, this process elim-inates the costs associated with mechanical production methods such laser or conventional machining which can also be provided where applicable.
Capable of exact channel repeatability, PEI Photo Etched Titanium Plates can also be made from stainless steels and other materials and incorporate permanent markings such as flow direction, part numbers, instructions, and logos. Applications include fuel cells, micro-channel plates, and stackable heat exchangers.
