Rotary vane vacuum pumps _ used in the mold industry

in the modern factory, in response to market competition, saves the manpower, improve quality and reduce cost is urgent task. Use can reduce the mould preheating time, mold temperature machine to improve surface quality of products, and make the production of fully automated. Extend the die life is a necessary means to improve productivity. Rotary vane vacuum pumps can be used for plastic mold industrial water machine and casting industry mold temperature machine, mold temperature control equipment. I want to make sure that many users will want to know why the mold temperature control equipment used in vacuum pump is feasible. Next, I will analyse the reason.

rotary-vane vacuum pump is widely used in mold temperature control equipment is:

1. Improve the efficiency of product molding;

2。 Reducing the generation of defective goods;

3。 Improve the product appearance, inhibition of product defects;

4。 To speed up the production schedule, reduce energy consumption and save energy.

through the use of the rotary-vane vacuum pump can improve the surface quality of plastic parts and precision of products:

1 to eliminate the appearance of the product defects. Avoid moving core, cavity surface temperature is exorbitant, clamping the material overflow, demoulding difficulty, the phenomenon of plastic parts to contract.

2 to avoid a large temperature difference of the cavity surface, the influence of temperature fluctuation influence on product shrinkage, stable product shape dimension precision, prevent warping and stress cracking after product release.

3 to improve mechanical and physical properties of plastic parts.

in die casting industry, rotary vane vacuum pump used in oil temperature machine notice:

1. Check whether there is enough heat medium quality and no pressure. Add hot oil, must be determined within the scope of the oil gauge, alarm is too low, starting is too high.

2, exhaust smoke, gas influence both in thermal efficiency, and affect the efficiency of pump, to run the first 10 minutes, normal pressure, after heated to 120 degrees, and exhaust.

3, be especially careful when refueling do not have impurities, with examples of damage to the water pump head. To stable synthetic oil, please change regularly, stop temperature and reduce the size of scale.

4。 Mold material selection requirements has high wear resistance and hardness, heat treatment must be conducted, and good heat treatment before cutting.

die temperature machine, rotary vane vacuum water pump selection or want to find regular rotary-vane vacuum manufacturer, shenzhen heng to mechanical and electronic research devoted to rotary vane vacuum pump schemes. Solve your worries.
