The injection molding process, used by injection molding tooling suppliers consists of four stages:


Before the material is fed into the mold, the two halves must be securely closed by the hydraulically powered clamping unit which pushes the mold halves together.


Raw plastic termed as the shot is injected into the machine. While advancing towards the mould, it is melted by heat and pressure and eventually injected into the mold cavity.


Cooling process of the molten plastic begins when it comes into contact with the interior mold surfaces, solidifying into the desired shape. There are also cooling solutions applied during mold design which aid the process.


Ejection system is used to eject the cooled part from the mold. Force has to be appliedas the part shrinks and adheres to the mold while cooling.
