Generally no more than 100 bar.The lower the back pressure, better to avoid wear. The parison is mounted on the machine’s nozzle, then put it into the mold, the mold is divided into two halves. Cooling for a few seconds in the mold, and the cooling before demolding.
It is only necessary to be empty; if it is more than 15 minutes, it is cleaned with viscosity PE, and the tube temperature drops to the PE temperature until it is turned on. 2, the retention time should not use too long retention time to prevent a decrease in molecular weight. Clear additional materials at both ends and complete the product. The content of the article comes from the network.
The injection is usually completed in 4 seconds. silicone valve cap Manufacturers It is usually not required. Try to avoid temperature above 300 ° C. 2, the hot air is passed through the blow, expand the shape of the mold. If the stop is less than 15 minutes.
Plastic Bottle Embryo Production Factory Blowing Process Introduction 1. But too fast, the shear rate is high to make the material are fragile. Injection molding machine selection PET due to the short time after the melting point is short, and the melting point is higher, there is a need to use more temperature control segments, and the injection system, which is self-compromising self-compromise, and the product (aqueous mouth) actually
The weight cannot be less than 2/3 of the machine injection amount.Plastic Bottle Embryi Production Factory Injection Point 1, injection speed general injection speed is fast, and it can prevent injection from premature solidification
