Shanghai Daoqin Plastics Co., Ltd.

        TPR/TPE and other injection molding products easy surface surface dark light, or gloss, color non-uniform.

         for/regarding this type of phenomenon, summary nano generate causes and solutions.

        (1) injection speed degree fast, material time long 也会引起 products surface gloss decline

         issues solutions: reduce injection speed degree, decrease/reduce time.

        (2) material heat stabilized property 差, hot separation understanding

         issues solutions: selection heat stabilized property good, gloss degree good material or in material in add heat stabilized agent.

        (3) material temperature degree low, nozzle temperature degree low 也会导致 products surface gloss degree decline

         issues solutions: improve/increase nozzle temperature degree, improve/increase melt temperature degree.

        (4) mold temperature degree low, cooling speed degree fast, melt also in 充模时, in type upper formed hard housing/shell, housing/shell to various force function, make 之变白变浑, reduce products surface gloss degree

         issues solutions: improve/increase mold surface temperature degree, reduce cooling speed degree or in mold gate using/adopting local add hot and other measures.

        (5) mold surface light degree 差, make products surface gloss

         issues solutions selection carbon tool 钢, fine light mold surface, improve/increase mold surface light degree.

        (6) use demolding agent amount more, make products surface 出现此 type defect

         issues solutions: 应该尽 amount use or use a small amount of demolding agent, coating need uniform.

        (7) 塑化时 back pressure small make material material 塑化不均, material material and color agent mixed combined good products surface color non-uniform,

         issues solutions: 应该适当 increase back pressure.

        (8) material in mixed has 杂质, drying make products surface gloss degree decline

         issues solutions: 应该想 method remove 杂质, separation drying material material, necessary increase material drying device.

        (9) runner, gate dimensions small, gas defect 也会造 formed products surface gloss good

         issues solutions: add large runner, gate dimensions, increase gas 槽.
