Blown plastic products factory said blow molding technology is a plastic processing methods, which in the present has been rapid development, so the technology is constantly improving. Then its application will become very wide, blow molding technology can not only be used for industrial packaging containers, but also in industrial packaging containers have a very wide range of applications.
In fact, according to the parison production method, blow molding can be divided into extrusion blow molding and injection blow molding method. Blown thermoplastic resin by extrusion or injection molding of the tubular plastic parison, in the case of relatively hot, it will be placed in the mold, wait until the mold, the rapid access to the compressed air in the parison, so It can make the plastic parison inflated and close to the mold wall, the cooling stripping, so we can make we usually see empty products. Commonly used in blow molding plastics are polyethylene, polypropylene, polyvinyl chloride, polyester, etc., so in the industrial packaging containers have a very important application.
