Blow molding is better. The granular plastic raw materials are heated and melted into molten plastic embryos. The plastic embryos enter the mold with a certain shape through different raw material output modes. After the embryo output is completed, the mold will be closed, and the mold will be closed at the same time, The blowing system of plastic hollow forming equipment will inject compressed air into the mold embryo from different positions of the mold to blow the mold embryo and make it close to the inner wall of the mold.
Blow molding manufacturers initially form a certain shape and complete the processing process of plastic products after cooling for a period of time. Extrusion blow molding machine extrudes raw materials into the mold, while injection blow molding machine injects raw materials into the mold. In addition to the different molding methods of raw materials, the other processing processes are the same, and the plastic hollow molding machine is a general term for extrusion blow molding machine and injection blow molding machine.
The working principle of plastic hollow molding machine enables it to produce plastic hollow products of different specifications, including large, small, different shapes, different wall thicknesses, different weights, different application scenarios, etc. Such as plastic bottles and cans, children's toys, large industrial buckets, chemical buckets, multi-layer buckets, mobile toilets, septic tanks, etc.
