Injection Must Learn Knowledge Points 1.Nozzle The melt usually flows from the nozzle into the nozzle, but with some molds, the nozzle is part of the mold because it extends to the bottom of the mold. There are two main types of nozzles: open shot nozzles and closed nozzles. In injection molding, open nozzles…
Sandwich Injection Molding The sandwich injection molding process injects a core material into the outer skin. The process takes place in two or three steps in one cavity. First, the material of the stroke surface layer is injected into the cavity portion space. The core component is then injection molded through its first material into…
Alternate Injection Molding Alternate injection molding alternately injects the same plastic component of two different colors into the same cavity. Both colors are placed in a special mixing nozzle before entering the mold. The two-color components are mixed to form a color effect. The two colors can be purposefully mixed to configure. In the alternate…
Composite Injection Molding And Core Retraction Process In the core retreat production process, the hollow portion of the mold is first closed and later reopened using a sliding core or slider within the cycle. When producing a part with two components, the first injection molding stage first injects the prefabricated component and then opens the…
