Injection molding lifters play a crucial role in the manufacturing process, ensuring smooth and efficient production of high-quality plastic parts. Home /. It’s a passage that connects the molding machine’s nozzle to the cavity of the mold. The mold is composed of two halves, the “A” side and “B” side. The term “cold runner” refers to the system of channels that delivers the plastic to the mold, which is not heated. Rather than use a side-action cam, an insert is machined so the undercut can be applied and is bolted into the mold where a pocket matches the insert dimensions. Due to Xometry’s Manufacturing Partner Network,. This is in contrast to a “hot runner” system, which uses heated channels to deliver. Injection Molding Gets a Face Lift. Features that have circular undercuts or large internal threads. . The reasons and corresponding solutions are described as follows: 1. Undercuts are protrusions or recessions in a part that prevent the mold, after the part is formed, from sliding away along the parting direction. If the areas where the air is trapped do not have a vent, the pressure of the air pocket will approach the pressure. Efficient runner systems minimize material wastage by optimizing the flow of molten material, ensuring that the right amount reaches each mold cavity without excess leftovers in the runners.
