Custom Plastic Components Molded Parts
Our Plastic Injection Molding Process
1.Material preparation
Dry plastic pellets may be used as they come or blended with colorants or fillers.
2.Loading
The pellets are loaded into the hopper of the molding machine and transported by a screw in the barrel towards the mold.
3.Heating
The dry pellets are then heated inside the barrel of the machine until they form the liquid resin, in a fully molten state. The mold is also heated.
4.Injection
The molten resin is injected under high pressure into the heated mold cavity through a gate. The resin fills the cavity and takes the form of the mold tool.
5.Cooling
The mold is cooled to solidify the part within.
6.Ejection
The cooled and now-solid part is ejected into the loading bin by opening the mold. Ejector pins aid the removal of the part from the mold. A new injection molding cycle may now commence.
