Hollow blow molding factory talks about the operation difference between blow molding and injection molding


Author: MULAN -Plastic Molding Manufacturer

Hollow blow molding factory talks about the operation difference between blow molding and injection molding Hollow Blow Molding Plant The blow molding molds in China use the "injection + blowing" method, while the injection molds in the injection molding factory use the "injection + pressure" method. The injection molding is a solid core, and the blow molding is a hollow core. There are differences in the structure of the mold. The injection mold is to melt the plastic material and then inject it into the cavity. After cooling, it has been processed into the required shape. The formed shape is the basic appearance of the finished product. Hollow Blow Molding Plant The blow molding process is a rapidly developing plastic processing method, also known as hollow blow molding. For example, the beverage bottles that are often encountered are blown out, which is the application of blow molding technology. Hollow Blow Molding Plant Generally, the thermoplastic resin or tubular plastic blank obtained by injection molding is put into the mold, and then compressed air is injected into the mold after the mold is closed, so that the plastic blank is inflated and close to the inner wall of the mold, and then the required hollow product is obtained by cooling and demoulding. Blank production method, hollow blow molding plant Blow molding can be divided into extrusion blow molding and injection blow molding, and the new development direction is multi-layer blow molding and stretch blow molding. The product expression form of injection mold and blow mold is the main difference. The products manufactured by the injection molding process are usually thicker, the manufacturing is relatively simple, and the requirements for raw materials are relatively low. Hollow Blow Molding Plant Depending on the blow molding process, the thickness and transparency of the product are also different. Because of this, there are certain requirements for the toughness and tensile properties of the raw materials, and the processing requirements for the blow mold are relatively high.
