Microcellular Foam Molding technology produces thermoplastic parts that look solid but in fact contain millions of minute airpockets which in many case permits cost reductions and offers potential improvements in part quality. Microcellular Foam Molding technology ensures outerskin of unique stability without warpage or sink marks in production. Nitrogen or carbon dioxide is used as blowing agents. Patented Nonstop compressed blowing design ensure hom ogenizing of the melt/gas mixture. Homogenizing of melt/gas mixture keep in storage with invariable pressure, then inject into the screw and mould via a specialized valve, essential to prevent premature expansion to protect the whole foaming process. Light weight parts, reduced polymer consumption. Shorter cooling times, because the initial melt and mould temperatures are lower, ensure the excellent dimensional accuracy. Instant foaming molding with no holding pressure process, lower internal stresses, prevent damage to material characteristic beside short cycle and energy saving. Improved manufacture of thin-walled parts, so that applications can be produced with lower clamping force and, consequently, smaller and cheaper injection molding machines can be used. Cost saving would be realized by foaming technology used in big parts and thick-walled parts. Unique process with holding pressure decrease result in lower mold costs and mold design simplification. Machine with more than ten inventions and structure including two patents.
