Plastic mold temperature is too low or inconsistent

(4) Plastic mold temperature is too low or inconsistent.

(5). Injection plastic molded parts out when the top is too hot.

(6) Cooling is insufficient or movable, the fixed plastic mold temperature inconsistent.

(7). Injection plastic molding structure is irrational (eg stiffeners concentrated in the side, but far away).

Remedy

(1) Reduce the injection pressure.

(2) Reduce the screw forward time.

(3). Increase the cycle time (especially the cooling time). From the plastic mold (especially thick injection plastic molded parts) immediately after ejection immersed in warm water (38oC) makes injection plastic molded parts to cool slowly.

(4). Increase injection speed.

(5). Increase the plastic temperature.

(6). Cooling equipment.

(7). Appropriate to increase the cooling time or improve the cooling conditions, as far as possible to ensure moving plastic mold temperature consistent with the fixed plastic mold.

(8) According to the actual situation in permitting improved plastic parts of the structure.
