Now there are a lot of products are made of plastic, these products are made of plastic injection molding. In the molding process, if nitrogen is filled in, it can not only save materials, but also be more robust. In the process of injection molding, the material is put into the mold, then nitrogen is filled until the whole mold is filled, and then waiting for forming.
In the process of injection molding, the purity of nitrogen should be 99.99% or above, and the pressure should be determined according to different manufacturers. Generally, the pressure should be 1.5MPa or above. It is troublesome to use bottled nitrogen because it needs frequent air exchange. Therefore, Xiaobian still suggests the use of nitrogen generation system.
As long as the pure compressed air enters into the nitrogen generation system, high-purity nitrogen can be obtained, and then connected to the nitrogen pressurization system, the required pressure of nitrogen can be increased. And just press the switch, the whole process is fully automatic operation, can be unattended. The manufacturer only needs to maintain the system regularly.
