Application of air compressor in injection molding industry

As the power source of compressed air, air compressors are widely used in the national economy. There are small piston air compressors, medical silent oil-free air compressors, integrated integrated air compressors, oil-free and water-free screw air compressors. This should be selected according to the requirements of the compressed gas required by the industry. The injection molding machine is equipped with an air compressor, and the screw type air compressor is generally selected.

The injection molding industry is a relatively large industry in the national economy, such as toy molds, shoe molds, container molds, plastic wood molds, tube embryo molds, aviation molds, rotational molding molds, apparel molds, automobile and motorcycle molds, farm tool molds, etc. These industries all need to use air compressors.

　　 How is the air compressor used in the injection molding industry?

　　 Air occupies a certain space, but it has no fixed shape and volume. When pressure is applied to the air in a closed container, the volume of the air is compressed, increasing the internal pressure. When the external force is removed, the air will return to its original volume under the action of the internal pressure. If there is a movable object in the container, when the air returns to its original volume, the object will be pushed out by the pressure of the air in the container. This principle is widely used in production and life.

　　In the injection molding process, there is another technology that can make compressed air very important. That is gas-assisted injection molding technology. Basically all thermoplastics used for injection molding and general engineering materials (such as PS, HIPS, PP, ABS...) are suitable for gas-assisted technology. At present, gas-assisted technology is widely used in various plastic products, such as televisions, refrigerators, air conditioners or audio enclosures, automotive plastic products, home appliances, daily necessities, toys, etc.
