What is precision injection molding? Precision injection molding, strictly speaking, refers to the dimensional accuracy of plastic products produced through injection molding equipment, which can reach below 0.01mm, usually between 0.01-0.001mm in size. It is an injection molding production method. Hengchang has specially compiled relevant information on precision injection molding, hoping to be helpful to you.
Precision injection molding is mainly used in industrial and civilian products such as aerospace, automotive components, precision instruments, sports equipment, testing tools, etc.
Specific requirements for precision injection molding: Firstly, the injection pressure should be greater than 25MPa; Injection speed greater than or equal to 300mm/s; Product size accuracy of 0.001mm; The coefficient of standard deviation (rate of change) of product quality is less than 0.1%; Precision of opening and closing positions: opening ≤ 0.03mm, closing ≤ 0.01; The injection position accuracy (pressure holding termination point) is less than 0.03mm; The force balance of the pull rod is less than 1%; The pre molding position accuracy is less than 0.03mm; Balance between fixed and dynamic templates A: less than 0.03mm when the locking force is zero B: less than 0.005mm when the locking force is maximum; The temperature control accuracy of the barrel and screw is less than ± 0.5 ℃.
