The standardization degree of PE blow molding machines in China is constantly improving. It is estimated that the coverage rate of standard parts for PE blow molding machines in China has reached 30%. Developed countries in foreign countries generally have about 80%.
It is necessary to use high-quality steel and apply the corresponding surface treatment technology to improve the life of PE blow molding machine. Whether the heat treatment and surface treatment of PE blow molding machine can give full play to the key aspects of PE blow molding machine steel material performance. The development direction of PE blow molding machine heat treatment is vacuum heat treatment. The surface treatment of PE blow molding machine is not only perfect, but also advanced techniques such as vapor deposition (TiN, TiC, etc.) and plasma spraying.
