anti 止 plastics material material 发脆

产 material 发脆常常 due to material material in injection molding process in degradation or other 启事.

⑴ injection molding issues issues:
<1> material temperature degree low, front material temperature degree;
<2> nozzle temperature degree low, front it;
<3>若 is material material light easy thermal degradation, drop material nozzle temperature degree;
<4> front injection speed degree;
<5> front injection pressure;
<6> growth injection 时刻;
<7> growth full pressure 时刻;
<8> mold temperature low, front it;
<9> made parts internal stress large, decrease internal stress;
<10> made parts has 拼缝线, method decrease or 消弭;
<11> screw speed high is degradation material material.

⑵ mold issues issues:
① products design thin;
② gate small;
③ separation runner small;
④ products growth add strong/high 筋, inner 角.

⑶ material material issues issues:
① material material 污染;
② material material drying good;
③ material material in has material;
④ material material in material more or material 次数太 more;
⑤ material material strong/high degree low.

⑷ equipment issues issues:
①塑化容 amount small;
② material in has material make material material degradation.
