Electric spark machining of aluminum alloy mold materials
The mold material should be selected according to the type of the molding resin (plastic), the number of productions, and the economy. For general-purpose mass production or engineering plastics, which require wear resistance, steel is mainly used as a mold, while non-steel metal materials such as aluminum alloy are used for molds of various varieties and small batches or trial production.
