Among the many advantages of plastic injection molding are the following:
Thousands of plastic resins to choose from for any application
Most cost-effective way to make large volumes of parts fast
A single tool can last for up to millions of cycles
Excellent surface quality and dimensional characteristics can be achieved
Different plastics can be overmolded for even more design options
The process is stable and reliable for predictable results

Plastic Injection Molding Process
once your plastic injection mold tools are ready, the molding process consists of the following basic steps:

Step 1. The plastic resin comes in raw pellets. These are dried to the right moisture content, and then if necessary they can be blended with pigments or master batch colorants.

Step 2. The dried pellets are poured into the hopper of the molding machine. A reciprocating screw inside the barrel of the machine will transport these pellets towards the mold.

Step 3. Within the barrel, the pellets are mixed and heated until fully molten, forming the liquid resin.

Step 4. The heated mold closes automatically and resin, under great pressure, is injected through a gate and into the mold cavity.

Step 5. The mold is cooled to solidify the part inside.

Step 6. The mold opens and the part is ejected to begin a new cycle.
