Chemical etching/chemical milling is an excellent choice for customized thin metal parts, it is different from stamping and laser cutting, for stamping, once your design confirmed, you can’t change the design at will. For chemical etching/chemical milling, it is easy to make the prototypes without any tooling charge and quick lead time (normally is 3 …
