The Plastic Injection Molding Process
Plastic injection molding is the process of filling a mold tool with liquid plastic resin under great pressure. The tool may comprise a single cavity or hundreds of cavities in order to make indefinite numbers of parts. Once the mold tools have been carefully designed and manufactured, 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 to create the correct color for the design.
- Step 2 – The dried pellets are poured into the hopper of the molding machine. A reciprocating screw inside the barrel of the machine is used to transport these pellets towards the mold while at the same time heating them.
- 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 in a short amount of time to solidify the part inside.
- Step 6 – The mold opens and the part is ejected to begin a new cycle.
