The extrusion molding manufacturer heats and melts the granular plastic raw materials into plastic embryos in molten state. The plastic embryos enter the mold with certain shape through different raw material output modes. After the output of the mold embryos is completed, the mold will be closed. While the mold is closed, 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, make it close to the inner wall of the mold, initially form a certain shape, and complete the processing process of the whole plastic products after cooling for a period of time.
In addition to what we know, many things in our daily life are also produced by plastic hollow molding machines. Water barrier, plastic tabletop board, plastic tray. Plastic solar liner, etc. The 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 main feature of the hollow blow molding machine is to continuously extrude the die head, follow the characteristics of raw material fluidity and the "first in first out" principle, make the die head extrude the tube embryo with good quality, completely eliminate the fusion line and residual stress, and change the material and color quickly, so that all products can meet the high-quality requirements.
