vacuum pump in injection molding

Plastic processing is the most indispensable part of injection molding, generally including plastic ingredients, molding, processing, connection, decoration and assembly. EVP vacuum pump manufacturer intends to introduce the application of vacuum pump in plastic parts processing. In the field of vacuum production in plastic parts processing, we provide you with various technical options.

1. Vacuum system is an independent vacuum technology solution, which is used for melt degassing in extrusion process. It has the characteristics of high vacuum, stable performance, long service life, compact structure and small floor area.

2. Oil free vacuum pump is a kind of mechanical vacuum pump which can work without any oil lubrication. It has the advantages of simple structure, convenient operation, convenient maintenance and no environmental pollution. With good durability, it is a dual-purpose vacuum pump for vacuumizing, compressing and obtaining vacuum, and is a basic equipment with wide application range. Therefore, it is an ideal part of pneumatic conveying or degassing system.

3. Screw vacuum pump adopts dry compression technology to achieve high pump speed and high vacuum level.

4. Rotary vane vacuum pump can be described as the overall industry standard vacuum pump. With its reliability and durability, vacuum pumps can be used in almost all fields of plastic processing.

For injection molding, the most indispensable step is drying the material. Most engineering plastics are hygroscopic, and plastic particles are susceptible to moisture due to the influence of external weather. Injection molding products with this high moisture content of raw materials will lead to obvious quality problems, such as bubbles or spots, and even reduce the performance of products in serious cases. Therefore, the screw vacuum pump should be used to dry the plastic raw materials in the production process.

Variable pitch and free exhaust greatly improve the ability of screw rod vacuum pump to deal with liquid and dust. Its unique temperature distribution plays an anti-corrosion role, and the optimized efficiency reduces the heat load, thus prolonging the service life of the vacuum pump.

dry screw vacuum pump advantages:

1. The surface of working chamber and screw rotor has anti-corrosion coating, which can adapt to harsh working conditions;

2. The gas is not compressed in the pump, so it is suitable for extracting condensable gas;

3. No oil consumption and no water dripping;

4. Simple structure and convenient maintenance;

5. The pumped gas is directly discharged from the pump body, which does not pollute water and environmental protection pressure, and the gas recovery is more convenient.

With the help of our screw vacuum pump, engineers can provide you with a variety of cost-effective and reliable vacuum solutions to meet the requirements of the plastic industry.
