What Is Die Casting?

Injection Mould Die Casting
Product applicationPlastic productsMetal products
ProcessInjecting a heated and melted material into a mold cavity under high pressure and cooling and solidifying to obtain a molded product
A molten alloy liquid is poured into a pressure chamber, a cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting.
Temperature controlThe barrel temperature ,nozzle temperature and mold temperature need to control.The mold cavity temperature exceeds
700 degrees
Pressure control①The plasticizing pressure depends on the type of plastic used.Metal liquid fills cavity under pressure, the common pressure is 15-100MPa.
②The injection pressure is based on the pressure applied to the plastic by the top of the plunger or screw (converted from the oil pressure)
Molding cycle①The filling time is about 3-5 seconds.①The metal liquid fills the cavity usually at 10-50 m / s, and some can exceed 80 m / s.
②The dwell time is about 20-120 seconds ( special thick parts can be up to 5-10 minutes )② The cavity can be filled in about 0.01-0.2 seconds (depending on the size of the casting).
Feature①Production is fast due to the flexibility in the molding process①Efficient process with a high degree of accuracy
②Plastic Injection molds can accommodate different plastic or polymer materials②No need secondary processing
③Fillers can be used in plastic molds to increase strength③Complicated designs can be easily made
④Efficient process with very accurate finishes
