Air compressor, as the power source of compressed air, is widely used in the national economy. There are small piston type air compressor, medical mute oil free air compressor, integrated integrated air compressor, oil free and non water screw type air compressor, this should be selected according to the requirements of the compressed gas required by the industry. The air compressor used in the injection molding machine is usually made of screw air compressor.
Injection industry is a relatively large industry in the national economy, such as toy molds, footwear molds, container molds, plastic moulds, tube moulds, aeronautical moulds, rolling molds, clothing moulds, molds and molds, etc. all these industries need to be applied to air compressor.
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 internal pressure. If there is a moving 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 is able to make the role of compressed air very important. That's the gas - assisted injection molding technology. Basically all thermoplastic materials used for injection molding and general engineering materials (such as PS, HIPS, PP, ABS... It is applicable to gas assisted technology. At present, gas assisted technology is widely used in various kinds of plastic products, such as TV, refrigerator, air conditioning or sound shell, automobile plastic products, household appliances, daily necessities, toys and so on.
