in structure foaming injection molding parts molding in, usually using/adopting chemical foaming agent, due to its generate foaming pressure relatively low, production made parts in thick and 形状方面受 to made. micro foaming injection molding parts molding using/adopting ultra- 临界 inert property gas to made. micro foaming injection molding parts molding using/adopting ultra- 临界 inert property gas 体（CO2, N2） as is material foaming agent ． its process process separation is 四步: 1） gas solvent understanding: will inert property gas ultra- 临界 liquid through in upper injection device polymer melt in, formed versus polymer / gas system; 2） formed 核: process in gas pressure decline from polymer in 析出而形 formed a large amount of uniform gas 核; 3） bubbles long large: gas in temperature degree and pressure control lower long large; 4）定 type: bubbles long large to dimensions 时, cooling type. micro foaming and generally material foaming has relatively large different. 首先, micro foaming processing process in need a large amount of inert property gas 体如CO2, N2 solvent understanding polymer, make gas in polymer saturated and 状态, using/adopting generally material foaming processing methods can can in polymer gas versus system in to this high gas concentrated degree. its 次, micro foaming formed need large large ultra- generally material foaming molding using/adopting is hot force 学状态逐渐改变 methods, easy product in large 泡孔以 and dimensions distribution non-uniform 弊病. micro plastics molding process in hot force 学状态迅 speed 改变, its formed speed rate and 泡核数 amount large large ultra- generally material foaming molding. and generally foaming molding versus ratio, micro foaming molding has many advantages. its is it formed bubbles small, can production generally foam plastics in micro relatively large difficult production thin 壁（1mm） products; its is micro foaming material gas is structure, can use and retardant property packaging product; its is production process in using/adopting CO2 or N2, 因而没 has ring 境污染 issues. USA Trexel company in MIT micro foaming concept upper, will micro foaming injection molding parts molding technology achieve industrial 化, formed MuCell patent technology. MuCell艺 used for injection molding parts main/primary advantages is, reaction is hot reaction, melt viscosity low, melt and injection molding parts mold temperature degree low, therefore products molding cycle, material consumption and injection molding parts pressure and clamping force reduce, but also its 独特之处 also in this type of technology can used for thin products and other foaming technology method foaming products injection molding parts. MuCell in injection molding parts molding technology upper breakthrough is injection molding parts products production provide front other injection molding parts process tool has large can force, is new type products design, optimization process and reduce product cost new 途径. using/adopting MuCell technology injection molding parts products positive by used for many industrial field/area, automotive, 医药, electronics, food packaging and other industry.
