        复式 injection molding can use reinforcement product use property, 如进步 chemical resistance, reinforcement property, more soft/flexible more tool force.

        复式 injection molding can 一开始 by use 美化消费 product appearance, 现颇受欢迎. various use selection this can, can use reinforcement product use property, 如进步 chemical resistance, reinforcement property, more soft/flexible more tool force.

        复式 injection molding can: in injection molding in commonly used material is thermoplastic property elastomer (TPE). can used for injection molding material product types already large is add. in 基材(如ABS, PC, PC/ABS, PA and SAN) upper 进行复式 injection molding, and selection TPE has SEBS, TPE-V, TPE-U, TPE-E and TPE-A and other.

        不 tube/pipe is selection parts injection molding still is injection molding, is will thermoplastic property elastomer (TPE) injection molding in and versus rigid property upper. this make “ soft hard ”商 product use property to reinforcement, insulation property, chemical resistance, add combined type engineering 学, more 佳 手感, property and 拔尖 美感.

        嵌 parts molding: parts molding in, made formed rigid property parts (generally is comparison hard plastics parts), will its 嵌入模穴 in, rear in this parts upper use TPE injection molding, most to good product. injection molding equipment can used for parts molding. rigid property parts can 够经 人工 or machine 械手臂 完结.

        二次 injection molding: injection molding 也叫做两次 injection molding, di color molding or more raw materials molding. this type of lower use specialized machine belt/tape has more material 筒, use toward mold in 写入不 same material. injection molding in adhesion property in injection molding in, solid and TPE间 adhesion property is processing can formed need 害. relatively adhesion property can make 如剥离, bending, abrasion loss or delamination and other 疑问. types material versus property and processing temperature degree is effect/influence adhesion strong/high degree important factors.

        材 material versus property: same hard / soft material combined adhesion strong/high degree

         processing temperature degree: it TPE熔 melt temperature degree, rigid property temperature degree and adhesion strong/high degree between 联系. TPE in injection molding in use polyester is thermoplastic property elastomer (TPE-E or COPE), is 由DSM engineering plastics 出产. this category of polyester elastomer tool engineering plastics strong/high degree, processing features and hot solid property elastomer use, processing, rate and chemical resistance.

         large more 数手感 soft/flexible injection molding use and thin thin soft property material (TPE) injection in hard 质基材 upper. is TPE generally demand relatively long and thin 壁区 充入 mold, therefore TPE tool has relatively high flow property. low viscosity product specifications optimization about/regarding injection molding 而言至关 important adhesion property, is this processing use 首选资 material.

         chemical adhesion: TPE经 复式 injection molding and used as rigid property 基材 极 property polymer (如PC, PC/ABS, ABS) adhesion non good. is this 一杰出 adhesion property, in non large lower 也不会呈现 its and delamination table/sheet 象.

         in outer table/sheet elastomer process in, TPE excellent 良 布局 features and good outer table/sheet 感观功 use, 并联系 TPE in injection molding in processing use. material combined or adhesion agent use: in TPE and non property polymerization 体(如PP) or PA between 进行复式 injection molding 时, selection machine 械联锁描绘 进步 and 基材 联 combined force. remove outer, can use adhesion agent or 底漆 进步柔质TPE and non property polymerization adhesion force.
