EDM plastic surface finishes

EDM (full name: Electrical Discharge Machining) is a kind of mechanical processing equipment, mainly used for blind hole processing and cavity forming in the molds, all kinds of complex curved surface by electricity spark machined. Widely used in various kinds of metal molds, machinery and equipment manufacturing.

It is used in pulse discharge between the two poles produced by galvanic action in working liquid, is special processing methods excluded conductive materials, also known as discharge machining or electrical erosion.
