What is precision injection molding?
What is precision injection molding? Strictly speaking, precision injection molding refers to the plastic products produced by injection molding equipment with a dimensional accuracy of less than 0.01mm, usually a method of injection molding with a size between 0.01-0.001mm. Fusan has compiled some information on precision injection molding, hoping to help you.
What is precision injection molding? Fusan will tell you.
Precision injection molding is mainly used in industrial and civilian products such as aerospace, automotive parts, precision instruments, sports equipment, and testing tools.
Specific requirements for precision injection molding: First, the injection pressure must 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%; the opening and closing position accuracy: open ≤0.03mm, close ≤0.01; the injection position accuracy (pressure holding end point) is less than 0.03mm; the stress balance of the tie rod is less than 1%; the pre-forming position accuracy is less than 0.03mm; the balance degree A of the fixed template and the movable template: less than 0.03mm when the clamping force is zero: less than 0.005mm when the clamping force is maximum; the temperature control accuracy of the barrel and screw is less than 0.5℃.
