The granular plastic raw materials, heated and melted into a molten state of plastic embryo, plastic embryo through different raw material output into the mold with a certain shape of the inside, after the embryo output is completed, the mold will be closed, the mold is closed at the same time, the plastic hollow molding equipment blowing system from different positions of the mold to the inside of the mold into the compressed air, used to blow the embryo, so that it is close to the mold inner wall, initially form a certain shape, after a period of cooling, complete the entire plastic products processing process.

As you can see, in the above introduction, Yankang Xiaobian mentioned that the plastic embryo enters the mold through different raw material output methods, and you may have questions about what different raw material output methods refer to.

In fact, this refers to different plastic molding methods, usually there are two kinds of extrusion blowing and injection blowing, which is what we call extrusion blow molding machine and injection blow molding machine. The extrusion blow molding machine is to extrude the raw materials into the mold, while the injection blow molding machine is to inject the raw materials into the mold. In addition to the different molding methods of raw materials, the rest of the processing technology is the same, and plastic hollow molding machine is a collective term for extrusion blow molding machine and injection blow molding machine.

The working principle of plastic hollow molding machine makes it possible to produce plastic hollow products of different specifications, including large, small, different shapes, different wall thicknesses, different weights, and different application scenarios. Like plastic bottles and cans, children's toys, large buckets used in industry, chemical barrels, multi-layer buckets, mobile toilets, septic tanks, etc.
