low molding technic is used in the production of hollow thin-walled parts with for thermoplastic materials.The Typical products of blow molding are large capacity and the final consumer goods,such as bottles and containers.At present,the most popular materials for blow molding are PE,PP and PVC. Blow molding process consists of two main molding methods:extrusion blow molding and injection blow molding.Through extrusion or injection molding.thermoplastic resin is molded into tube-shaped parison which are instantly(when it is still hot or heat it up to the state of softening)put into  blowing mold.  Then compressed air is blown into it until it expanded and sticked on mould cavity.  After cooling and demolding,hollow products can be finished Precision Plastic Injection Parts Plastic injection parts can be seen everywhere in industry and in daily life, and can be said to be the most used parts by humans. All industries such as automobiles, airplanes, ships, electrical and electronic, etc. will use more or less precision plastic injection molding parts, and even our daily washbasins, tooth cups, plastic chairs, power sockets, etc. are plastic injection molding parts. Its biggest feature is that it is widely used, high efficiency, low cost, and high product precision. However, since precision molds are required to form products before production, mold costs and mold opening time need to be invested in the early stage, which is not suitable for small batches of products. Moreover, the development of precision molds is very critical. Only by producing high-precision and durable molds can the accuracy and production efficiency of subsequent products be guaranteed. Therefore, the development of plastic molds is very important for the production of plastic injection parts.
