The injection mold mold itself according to the different materials, mold, mold can be divided into: sand molds, dies pp injection mold, vacuum mold, wax mold and so on. Among them, with the rapid development of polymer plastics injection mold Wugong County, plastic mold and people's lives are closely related. Plastic mold can generally be divided into: injection mold, extrusion mold, gas-assisted mold and so on. Mold plastic mold design requirements 1) mold parts have sufficient strength, we need to select a suitable mold material. 2) The mold should be avoided with the agency independent external convex and concave portions, the outer should be chamfered. 3) In principle, the guide post mounted on the lower mold and away from the operator, mold center Shank force near the center line, positioning and other important parts of the guide to make the operator to see clearly. 4) The design should take into account the operation, adjustment, installation, maintenance, handling and storage convenience, the operator safer. 5) tailored injection mold manufacturer world class quality mp3 injection mold injection mold, injection mold Wugong County, Chang Technology provided by Chang Technologies.
