        众 周知, fine 节决定 formed 败, most good material, 哪怕没 has good fine 节, will 会功亏一篑. especially is add 纤PC plastics raw materials, in injection molding modified process process in, must attention/notes its in fine 节 处理, most rear made as formed product has 不达标 rear 果.

         add 纤PC injection molding process must fine has which 呢?

        1) injection molding front 准备: PC raw materials although tool excellent machine features, by is “ anti elastic 胶”, meanwhile, transparent degree non high, by is is “ transparent metal ”, is, it has non heavy defect, that is flow property 差, injection molding difficult, therefore, PC raw materials injection molding front 准备十 separation key/critical, effect/influence formed 败.

        2) raw materials drying: due to PC plastics raw materials in water property upper has defect, water rear will effect/influence products dimensions and stability property can, therefore, processing front need drying 处理, good preheating temperature degree and time, ensure injection molding ring drying wet, effect/influence process.

        3) injection molding machine selection: for/regarding requirements is mixed combined good, corrosion resistant, 常规 塑化 screw difficult to, 而PC plastics products due to more use modified material, electrical product must increase anti property can, add flame retardant additives, for injection molding machine system requirements comparison high, generally machine difficult achieve.

        4) for temperature degree and gate 握: Common mold temperature degree is 80-100℃, add glass fiber (GF) is 100-130℃, small type products can use gate, gate deep degree has most thick 部位 70%, its it gate has ring and long 方形. gate large good, decrease low plastics by degree 剪切而造 formed defect. runner amount short 而圆.

         need good above fine 节, production excellent PC plastics raw materials product formed formed 章 事.
