How Plastic Injection Molding Works

Plastic Injection molding is by far the most common way to producelarge volumes of finished plastic parts for every kind of commercial and industrial use. Molten resin is injected under high pressure into the cavity of a metal die and then rapidly cooled, forming a solid shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.

The 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
