How to prevent shrinkage fluctuation of precision injection molding products?

Precision injection molding must be based on the premise that the mold can be made according to the required size. However, even if the mold size is fixed, the actual size of the product varies with the actual shrinkage. Therefore, the control of shrinkage rate is very important in precision injection molding.
Whether the mold design is appropriate or not determines the shrinkage rate, which also varies with different resin batches. If the pigment is changed, the shrinkage rate will […]

Delamination and peeling of injection molding

The causes of delamination and peeling in injection molding products are as follows
Material temperature is too low, injection mold temperature is too low, screw speed is too fast, resulting in internal stress.
The cold material hole is small, the fluidity is poor, and the material is cooled too fast.
The holding pressure is low and the back pressure is too low.
The raw material is mixed with impurities.
Release method:
Increase the material temperature, die temperature, reduce the shear force of melt flow, reduce […]

What causes short shot of plastic mold in injection molding?

Short shot refers to the phenomenon that the cavity of plastic mold is not completely filled due to the insufficient fluidity of plastic, resulting in incomplete plastic products. The main reason is improper injection pressure and speed (including excessive pressure loss caused by resistance), which is mainly affected by the following aspects:

1、 Injection molding machine
(1) Insufficient injection molding capacity – this is caused by the high capacity of the injection molding machine, which may also be caused by insufficient […]
