Precision injection moldingIn a strict sense, molding refers to the dimensional accuracy of plastic products produced by injection molding machine equipment, which can reach less than 0.01 mm, usually between 0.01 and 0.001 mm. Regal has specially sorted out relevant information about precision injection molding, hoping to help you.

What is precision injection molding? Lianxing will tell you

Precision injection molding is mainly used in aerospace, auto parts, precision instruments, sports equipment, testing tools and other industrial and civil products.

Specific requirements for precision injection molding: first, the injection pressure should be greater than 25MPa; Injection speed ≥ 300mm/s; The dimension accuracy of the product is 0.001 mm; The standard deviation coefficient (change rate) of product quality is less than 0.1%; Precision of opening and closing position: opening ≤ 0.03mm, closing ≤ 0.01; Injection position accuracy (pressure maintaining end point) is less than 0.03mm; The force balance of pull rod is less than 1%; The pre-plastic position accuracy is less than 0.03mm; Balance degree A of fixed and dynamic formwork: less than 0.03mm when the locking force is zero; B: less than 0.005 mm when the locking force is maximum; The temperature control accuracy of barrel and screw is less than ± 0.5 ℃.
