What is precision injection molding? Precision injection molding, strictly speaking, refers to the dimensional accuracy of plastic products produced by injection molding machine equipment, which can reach below 0.01mm. It is usually an injection molding production method with dimensions ranging from 0.01 to 0.001mm.

Precision injection molding is mainly used in industrial and civilian products such as aerospace, automotive parts, precision instruments, sports equipment, and inspection tools.

Specific requirements for precision injection molding: Firstly, the injection pressure should be greater than 25MPa; The injection speed is greater than or equal to 300mm/s. The dimensional accuracy of the product is 0.001mm. The standard deviation coefficient (rate of change) of product quality is less than 0.1%. Mold opening and closing position accuracy: 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-plasticizing position accuracy is less than 0.03mm. Balance of fixed and moving templates: A: less than 0.03mm when the clamping force is zero; B: less than 0.005mm when the clamping force is at its maximum. The temperature control accuracy of the barrel and screw is less than ±0.5℃.
