Plastic Injection Molding Design Pdf
Step 1 of the Injection Molding ProcessThe Injection Molding cycle timer begins when the mold closes.Note: In some cases, as with the use of robots, the cycle runs “part to part” which means the cycle begins and ends when the robot receives a new part or the new part touches the conveyor belt. STEP 2: INJECTIONThe heated plastic is injected into the mold. As the melt enters the mold, the displaced air escapes through vents in the injection pins and along the parting line. Runner, gate and vent design are important to insure the mold is properly filled. Step 5 of the Injection Molding Process STEP 6: REMOVING THE RUNNER AND PACKAGINGAlthough the injection molding machine’s cycle ends on Step 5, the process continues. Periodically the machine operators, or robots separate the usable parts from the left over runner.

The runner is the pathway that the plastic takes to fill the mold cavity. In many cases the runners are ground and recycled to reduce costs and environmental impact. The usable parts are then weighed, counted and packaged for assembly or shipping. Step 6 of the Injection Molding Process.Note: Molds with hot runner systems may not have a runner or waste because the pathway is maintained at a constant heat.
