Gas-assisted injection molding technology has brought considerable impact on plastic molded products, and solved the difficulties of injection molding thick parts, thin parts not easy to be molded, and the structure is easy to warp and deform, in addition to saving plastic 50%. Shorten the manufacturing cycle by 20%, reduce the number of parts by 70%, reduce the total cost by 20%, and reduce the product warpage by 30%, overcome the surface sag and shrinkage deformation, increase the structural performance of the product, and improve the quality of the finished product. It is quite extensive, and it is estimated that it can account for more than 15% of the market, especially for the domestic computer information industry, home appliance industry, auto parts manufacturing, etc., will have a considerable impact.
Gas-assisted injection molding technology, mainly in the traditional injection molding process, first injection of a fixed amount of molten resin, and then rapidly injected with high-pressure nitrogen gas, using gas to quickly and effectively continue to push the molten resin to fill the cavity, and Continue to maintain gas pressure until the product is formed. At present, some companies have developed products using this technology, including: car handles, computer monitor casings, baby carriage handles, TV casings, and office data cabinet curved panels.
