Chemical etching, also known as photochemical machining or photo etching, is a subtractive sheet metal machining process which uses chemical etchants to create complex and highly accurate precision components from almost any metal.
Etched metal flexure springs improve Thales’ space cryocooler performance
In this case study, we explore why chemical etching was chosen by Thales Cryogenics, the European leader in cryogenic technology, to produce flexure springs for a space cryocooler.
