1. Weld-free injection technology and equipment In the injection process, a special mold heating and cooling control system is adopted, and the mold is quickly heated to a certain temperature before injection, and the sol does not cool down during the flow, but quickly cools down after injection to shorten the molding cycle. This technology is mainly used in the production of plastic parts (such as TV front frame, etc.), high transparency plastic parts (such as car lampshade, etc.) and automobile central control panel without spraying. Can improve product quality and reduce production cost.
2. microcellular foaming low-pressure injection molding and extrusion technology and equipment. A certain proportion of inert gas (N2 or CO2) is dissolved in the sol, and the gas is precipitated to form tiny pores during cooling. The outstanding advantages of this technology are: reducing the viscosity of sol, reducing injection pressure, improving the dimensional stability of products, saving materials and so on. At present, the developed equipment and technology have been successfully applied to the industrial production of plastic sheet extrusion, and injection molding has also been successfully tested.
3. The sudden emergence of IMD technology in recent years will surely bring about a revolution in automobile interior decoration. The embedded in-mold labeling technology independently developed by our company will soon form industrial scale production.
