        密封 property is machine basic function, for/regarding injection molding machine 说, has 两处 密封 property must 引起关注, is machine system pressure system property and injection molding screw system property, front 者密封 property good system pressure, rear 者密封 property good 引起漏胶, 今天我们 issues is ~~ how to its property?

        1, how to injection molding machine is pressure?

         use will mold 调 紧 头, is let machine can 够一直 maintain high pressure 锁模但锁不 upper. high pressure pressure amount most large, 手动按锁模键, 一直按 不 need 松开, pressure table/sheet, is can 够一直维持指针不动, if 指针不会 slow slow lower slip 就说明油泵没 has pressure 情况, if slow slow lower slip 说明油泵 has pressure phenomenon

        2, how to screw system property (止逆 ring / screw property)

         in production in 熔胶完毕, again long 一会儿, product and runner system full cooling, semi is 手动, 开始射胶, meanwhile screw 位置, if screw slow slow front 移, screw system has 漏胶, 否则就 is has 漏胶.
