Injection Molding Process
The injection molding process takes various stages. Each stage must be carefully evaluated when considering part design, tool creation, and molded plastics production. The following are the primary steps in the injection molding process:
- Step 1: The mold closes: The injection molding cycle time starts off when the mold closes. Where robots are leveraged, the cycle will begin and end when the bots receive a new part or when the next part hits the conveyor belt.
- Step 2: Injection: The next step involves injecting the heated plastic into the mold. When the melt fills the mold, it displaces air, which is released through vents in the injection pins and along the parting line. Gate, runner, and vent designs are crucial because they guarantee the mold is adequately filled.
- Step 3: Cooling: After the mold has been filled, it is allowed to cool for a specified period to sufficiently harden the material. The cooling time is determined by the resin used as well as the thickness of the part. Ideally, each mold comes with internal cooling or heating lines that cycle water through the mold so that a consistent temperature is maintained.
- Step 4: Plasticizing the resin: As the temperature of the part goes down, the barrel screw retracts while drawing new plastic resin into the barrel from the material hopper. Heater bands are designed to maintain an ideal barrel temperature for the kind of resin being utilized.
- Step 5: Injection: The injection process involves the mold’s opening to allow for the ejector rod to move the ejector pins forward. The part will then fall off into a bin underneath the mold.
- Step 6: Packaging the runner: The bots or machine operators will separate the ideal parts from the leftover runners. The usable parts are weighed, counted, and packaged, ready for shipping or assembly.
