Epc (also called real mold casting) is to use foam (EPS, STMMA or EPMMA) polymer materials into to produce casting parts structure, is exactly the same size of mould,
After dip-coating refractory coating (reinforcement, bright and clean, well ventilated effect), and after drying, buried in the dry in quartz sand, 3 d modelling, vibration casting molding sand box under negative pressure condition poured into the molten metal, the polymer material model heat gasification, and then replaced by the liquid metal cooling solidification after the formation of the one-time forming new technology of casting production casting new casting method.
Disappear for die casting has many different name, the country''s main way and "dry sand mold casting," "negative pressure type solid casting", hereinafter referred to as EPS casting. Known abroad mainly include:
Compared with the traditional technology, the lost foam casting technology has incomparable advantage, foundry industry at home and abroad called "casting technology of the 21st century" and the "green revolution" in foundry industry.
Has the following characteristics: 1, casting quality is good, the cost is low; 2, any material, size, all appropriate; 3, high precision, smooth surface, and reduce the cleaning, save machining; 4, greatly reduce the defect, the casting organization density;5, which can realize large-scale, high-volume production; 6, suitable for mass production of the same casting casting; 7, suitable for manual operation and automatic assembly line production operation control; 8, production lines, production status as to meet the requirements of environmental protection technology parameters; 9, can greatly improve the work environment of casting production line and production conditions, reduce labor intensity, reduce energy consumption.
Pingyang county Kim mould co., LTD. (former wenzhou precision.our foam mold factory), founded in 1996, mainly engaged in EPS (bubble) packaging mould and the disappearance of the foundry mould two series of professional manufacturers, specializing in the production Foam mold, packaging mold, Vanish mold sponge mold And other products.
