Roots vacuum pump is an important vacuum equipment, which produces vacuum effect by rotating gears to drive two intermeshing impellers. Roots vacuum pumps have the characteristics of high airflow capacity, low temperature rise and high vacuum, so they are widely used in the field of plastic processing.

First of all, an important application of Roots vacuum pumps in the plastic processing process is the drying of plastic raw materials. In the production of plastics, plastic raw materials often need to be melted by high-temperature treatment, and the moisture in them is removed. The Roots vacuum pump through the generation of strong exhaust capacity, can quickly remove the water in the plastic raw materials, so as to ensure the dry degree of plastic raw materials.

Secondly, Roots vacuum pumps can also be applied to the pumping and curing of plastic molds. In the manufacturing process of plastic products, after the mold is filled with plastic, it is often necessary to discharge the residual gas by pumping to ensure the quality of the product. Because of its excellent exhaust capacity, Roots vacuum pump can effectively extract the gas inside the mold, thus ensuring the quality of plastic products.

In addition, Roots vacuum pumps can also be used in the vacuum system of plastic injection molding machines. During plastic injection molding, it is necessary to ensure that no gas is present in the injection cavity to prevent bubbles or defects. The Roots vacuum pump ensures a vacuum environment in the injection cavity by rapidly extracting the gas in the cavity, thus producing high-quality plastic products.

In practical applications, Roots vacuum pumps can also be combined with other equipment to further optimize plastic processing. For example, in a plastic drying system, equipment such as Roots vacuum pumps and hot air dryers can be combined to improve the drying effect of plastic raw materials. In the vacuum system of injection molding machine, Roots vacuum pump can be combined with the control system of injection molding machine to achieve automatic control, improve production efficiency and product quality.
