The heat dissipation problem in plastic injection molding

Plastic injection molding is a commonly used method of processing plastic products, which can process plastic products in various industries. INVITECH Precision—For more than 30 years, we have been engaged in customized processing services for precision injection molded parts. Various precision plastic injection molded parts can be customized according to customer requirements. In the injection molding process, heat dissipation is a common problem. So how to deal with the heat dissipation problem in the plastic processing process? Now let us find out.

In the plastic injection molding process, heat loss is an important aspect that needs to be considered. Usually, the loss of heat is caused by its uninterrupted transmission. In the production of plastics, there are mainly three heat transfer methods: radiation, convection and conduction. In addition to most of it being absorbed by the mold, a part of it is discharged into the air through radiation and convection.

When the mold is formed, it is necessary to increase the heat utilization rate. When the mold is cooled, the temperature needs to be quickly lowered. Therefore, the mold needs to be cooled on the battlefield. Generally speaking, the cooling medium is water. Because the water price is low, the cost is naturally low, and the water after cooling can be recycled. But in the final analysis, everything has advantages and disadvantages, and the low price and options make it only as a disposable coolant.
