compression molding

     compression molding 也称模 pressure molding or pressure made molding, compression molding main/primary used for aldehyde resin, aldehyde resin, saturated and polyester resin and other hot solid property plastics molding.

    挤塑

    挤塑 also extrusion molding, is use machine （ extrusion machine ） will add hot resin through mold, extrusion 需形状 products methods. has has hot solid property plastics molding, can used for foam plastics molding. advantages is can extrusion various products, production efficiency high, can 自动化, 连续化 production; disadvantages is hot solid property plastics can using/adopting method processing, products dimensions easy generate 偏差.

     injection molding

     injection molding also injection molding. injection molding is use injection molding machine （ or injection machine ） will thermoplastic property plastics melt in high pressure lower to mold inner cooling, solid obtain product methods. injection molding can used for hot solid property plastics and foam plastics molding. injection molding advantages is production speed degree fast, efficiency high, as can 自动化, can molding complex parts, especially combined a large amount of production. disadvantages is equipment and mold cost high, injection molding machine relatively difficult and other.

     blow molding

     blow molding also in blow molding or in molding. blow molding is pressure shrink gas pressure make combined in mold in hot resin type 坯吹胀 is products types methods, blow molding blow molding film and blow molding in products types methods. use blow molding method can production film products, various bottle, 桶, type container and toys and other.

     calendering

     calendering is will resin combined various additives 经预期处理（捏 combined, and other ） rear through calendering machine or more toward versus calendering 辊 间隙 processing formed film or sheet/slice 材, rear from calendering machine upper lower, again cooling type types molding methods. calendering is main/primary used for polyvinyl chloride (PVC) resin molding methods, can manufacturing film, sheet/slice 材, sheet/plate 材, 人造革, sheet/plate and other products.
