Microbubble injection molding technology has great potential in industrial applications

According to U.S. industry insiders, with the advent of gas back pressure injection and mold rapid heating and cooling technology developed by the Massachusetts Institute of Technology, licensed by Trexel, the injection micro-bubble forming technology has evolved from the laboratory stage to the industrialization stage, and it is expected that Wide application prospects.

Although the injection microbubble molding technology has the advantages of reducing the amount of plastic, creating special properties, shortening the molding cycle, reducing the clamping force, eliminating the surface depressions, and can provide cushioning, sound insulation, heat insulation, flexibility, etc. The disadvantage is that the surface quality of the parts is not as good as non-foaming parts and the tensile strength is low. However, the gas back pressure injection and the rapid heating and cooling technology of the mold have solved the quality problem of the surface of the workpiece.

According to Xu Jingyi, technical director of the United States injection microbubble molding machine manufacturer Engel Machine Company, injection microbubble molding is particularly suitable for parts that require high-precision thin-walled, large-planar and warp-free parts, and have a large flow rate ratio. The introduction of Mary's mold filling difficulties and the application of mold tonnage. He also said that if domestic companies are interested in new technologies, they can jointly develop with the company.
