OEM precision mold injection molding

OEM precision mold injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding method are fast production speed, high efficiency, automated operation, diverse colors and varieties, shapes from simple to complex, sizes from large to small, and precise product size. The products are easy to update and can be made into complex shaped parts. Injection molding is suitable for large-scale production and complex shaped products in the field of molding and processing.

Possible defects in the injection molding process of OEM precision molds

What are the possible defects that may be encountered during the process of mold injection molding? The author tells you that there may be defects encountered during the injection molding process of the mold, as follows: 1. The characteristics of defects in injection molded parts. The injection molding process is incomplete because the mold cavity is not filled with plastic or some details are missing during the injection molding process.

Possible reasons for the problem,
Insufficient injection speed.
Plastic shortage
The screw did not leave any cushioning material at the end of its travel.
Changes in running time.
The temperature of the injection cylinder is too low.
Insufficient injection pressure.
The nozzle is partially sealed.
The heater outside the nozzle or feeding cylinder cannot operate.
The injection molding time is too short.
Plastic is attached to the throat wall of the hopper.
The capacity of the injection molding machine is too small (i.e. injection weight or plasticizing ability).
The mold temperature is too low.
The rust proof oil on the mold has not been cleaned thoroughly.
The retaining ring is damaged and there is a backflow of molten material.
