QX Mould injection mold cooling system design1, The distance between water line and parting line should be more than two times water diameter or 15mm.2, The distance from water line to screw, ejection pins should be at least 5mm except for

Steel selection is the key.Regarding the small plastic molds, due to the high cost of production and the low cost of materials, it is preferable to use steel with good process performance, stable performance and long service life in the pro

1. Heat resistanceWith the emergence of high-speed molding machinery, plastic products production goes faster. Since the molding temperature is generally between 160 ~ 350 ℃, some poor mobility, fast forming speed, forming part of the mold
