Low Cost 2k injection molds Manufacturers:The vent is a Groove vent open on the mold for the discharge of the original gas and molten gas. When the melt is injected into the cavity, the air in the cavity and the gas brought in by the melt must be discharged through the exhaust port at the end of the flow.

Otherwise, the product will have stomata, poor connection, not ideal filling, and even due to the high temperature caused by compression, the accumulated air will also burn out the product. In general, the exhaust hole can be located in the cavity melt flow end or plastic mold type surface. The latter is a shallow groove, deep 0.03-0.2 mm, the side width of the mold 1.5-6 mm. In the injection process, the vent will not have too much melt seepage, because the melting experience there cooling solidification, clogging the channel. The opening position of the vent cannot be directed at the operator to prevent the melt from accidentally spraying and injuring the person.
In addition, the mating gap between the ejector rod and the ejector hole, and the matching gap between the ejector block and the release template and the core can also be used for exhaust.
Structural parts refer to the various parts that make up the mold structure, including guidance, demoulding, core pumping, fractal and other parts. such as front, rear splint, front, back buckle template, load-bearing plate, load-bearing column, guide column, off the template, stripping rod, return rod and so on.
