The exhaust system for ensuring product quality plays a vital role in shaping: A, the use of exhaust ducts of plastic molds, exhaust ducts, generally located in the cavity is filled with the last part, because of the depth of the plastic exhaust ducts varies, basically no plastic burrs maximum gap allowed to determine, such as ABS 0.04 to 0.02mm or less marl match steel 0.02. B utilizing core inserts Putters with the gap or dedicated exhaust vent plugs; C sometimes cause a vacuum in order to prevent distortion products at the top out, will set up gas marketing; D products and sometimes in order to prevent a vacuum suction mold, designed anti-vacuum components. Plastic mold plastic mold for compression molding, extrusion, injection molding, blow molding, and low foaming modular plastic mold. Plastic processing industry and plastic molding machine supporting, giving plastics to complete configuration and precise dimensions of the tool. Because many plastic varieties and processing methods, structural plastic molding machines and plastic products also of sophistication varies, therefore, the type and structure of the plastic mold is varied. Structure includes a substrate by a combination of the die, die components and die combination of card board composed of plastic mold die cavity with variable Ltd, by a combination punch board, punch assemblies, punch combo card board, truncated cavity components and side cut-combination plates with variable core punch. Convex mold, coordinated and assisted molding die change systems. Processability of different shapes, different sizes of plastic parts series. In order to improve the performance of plastics plastic mold factory in Shenzhen, but also add a variety of supplementary material in the polymer, such as fillers, plasticizers, lubricants, stabilizers, coloring agents, in order to become a good performance plastics.
