Temperature Control in Plastic Processing

In the plastic processing link, temperature control is a very big factor affecting plastic processing. If the temperature is not well controlled, it is very likely to cause damage to the items and errors in production. What are the aspects of these temperature control?

1. Barrel temperature. In the process of plastic processing, the control of barrel temperature mainly affects the flow and cooling of plastics. Each type of plastic has a different flow temperature, so the barrel temperature to be selected is also different.

2. Nozzle temperature. The nozzle temperature of plastic processing is generally lower than the barrel temperature. This is mainly to prevent the molten material from "drooling" in the straight-through nozzle; however, the temperature of the nozzle cannot be too low, which will also cause the molten material to solidify prematurely and block the nozzle.

3. Mold temperature. Mold temperature will have a great impact on the intrinsic performance and performance quality of the product. The temperature of the plastic processing mold largely determines the presence or absence of crystallinity. The size, structure and performance of the product are also greatly affected by the mold temperature.

Qingdao Xueyu Molding Products Co., Ltd. is mainly engaged in the design and manufacturing of injection molds, injection molding and secondary processing (spraying, pad printing, ultrasonic welding, stamping), etc. For more information about plastic processing, please contact us.
