Clamping system ' s design of blow molding machine with double molds 中空吹塑成型机双模具合模装置的设计
For example , the grease - lubricated sliding 45 carbon steel bearings were used in the clamping unit of plastic injection molding machines . the elements of plastics are always polluted by the lubricating grease 例如:注塑机合模装置用脂润滑45钢轴承,在使用过程中润滑油脂常常污染模塑件,废弃的润滑油脂也存在环境污染问题,不符合清洁生产的要求。
