挤注 molding 闪亮出场
    定 long relatively long type, thin 壁, type 材模样 塑 parts injection molding, 一直受 to use material flow property can made. extrusion can provide use production long product 需 灵 active property, for and extrusion direction formed 一定角 degree structure or 几何形状, extrusion technology method achieve.

    一项名 is Exjection（挤注 molding ） new technology not only extrusion and injection molding technology advantages, meanwhile also it disadvantages, can utilizing injection molding technology production type type parts.

     in K2007 exhibition upper, 恩格尔 company (ENGEL) in Emotion200/55 full electrical injection molding machine （ clamping force 550kN） upper Exjection technology formed is 展会一 large 亮点. 恩格尔现场 use this system production thick 1.2mm, external dimensions 930mm thin type 材.

    Exjection and injection molding technology main/primary difference in 於: injection melt material meanwhile, tool has 一定剖面形状 mold and machine formed combined 适 角 degree 移动.

     is ensure positive mold cavity filling, need adjustment screw front speed degree, 以精准 adjustment melt speed, combined mold speed degree. mold 移动形 formed 连续 自由 mold cavity 空间, by 流入 熔 melt material 填满. is for melt material generate pressure shrink function, make made parts 密实并避免 shrink 痕, melt material in injection 点 附近 by pressure shrink, is 说, mold ratio melt material flow 规定 理论 speed degree need 移动 稍 slow, achieve 一定 无 pressure filling. this conditions can through ENGELE-motion series full electrical injection molding machine achieve. mold by 伺服马达 and 往复移动 滚珠 filament 杆 推动, ensure injection and 移动 同步. mold inner E-motion锁模 plant/unit provide 极佳模 sheet/plate degree and 特定区域 in uniform pressure shrink distribution, not only can generate flash, also make formed clamping force 时移动 mold force amount small.
