模具分为金属成形模和非金属成形模两类,塑料模具是非金属成形模具中主要模具类型之一。金属成形模具,有冲压模、锻模、压铸模、铸造模和粉末冶金模;非金属成形模具,有塑料模、玻璃模、橡胶模。随着石油、化学工业的发展,塑料已成为工业生产中的一种主要原料,而塑料制品成形模具用钢已发展成为一个独立部分。据资料报导。日本塑料模具生产额为整个模具生产的28%,近三分之一。塑料模具用钢年耗损量,1965年为4400吨,1974年为14000吨,1975年为18000吨,是日本10年前的4-5倍。近年已超过30000吨。我国塑料模具用钢目前处于发展阶段,缺少塑料模具专用钢种,生产部门通常采用市场能供应的通用
Mold is divided into two types of metal forming molds and non-metal forming molds, plastic molds are one of the main mold types in non-metal forming molds. Metal forming mold, a stamping die, forging die, die-casting mold, casting mold and powder metallurgy; non-metallic forming mold, plastic mold, glass mold, rubber mold. With the development of petroleum and chemical industry, plastic has become a major raw material in industrial production, and steel for forming plastic mold has become a separate part. According to the information reported. Japan plastic mold production for the entire mold production 28%, nearly one-third. The annual consumption of plastic mold steel, 4400 tons in 1965, 14,000 tons in 1974 to 18,000 tons in 1975, Japan’s 4-5 times 10 years ago. In recent years, more than 30,000 tons. China’s plastic mold steel is currently in development stage, the lack of special plastic mold steel, the production sector is usually available in the market can supply generic
