What is plastic injection molding?
The most commonly manufacturing process for making plastic parts is Injection molding.
the most commonly materials is thermoplastic and thermosetting polymers.
Injection molding requires an injection molding machine, plastic raw material, and an injection mold. The raw plastic material is melted in the injection unit and then “shot” then injected rapidly into the mold under high pressure. The plastic material is cooled by BTC mold unique cool system, and the circulating water through the mold to transfer and remove the heat from the steel mold, part solidifies as cooled. The part is ejected from the cavity of the mold when mold opening . The entire process or “cycle” is completed in seconds and then repeated.
The key steps in injection molding:
Clamping
The mold’s two sides are sealed shut under hydraulic pressure.
Screw Recovery
Plastic material is fed into the barrel and conveyed via rotating screw down the barrel toward the front of the screw. As the material is conveyed it is heated to the specified melt temperature creating the “shot” or volume of material to be injected.
Injection
Screw is pushed forward injecting the material under very high pressure into the mold.
Cooling
Water circulated through channels in the mold to remove heat and solidifies the molded part.
Ejection
The clamp releases, mold opens and part is ejected from the mold.
