         di color injection molding most important process is filling and holding pressure, lower 面, to large 家说说, di color injection molding processing in how to control pressure.

        1.  injection pressure

         in currently di color injection molding processing production in, has injection machine injection pressure is 以柱塞 or screw for plastics pressure (由油路 pressure 换算) is 准. injection pressure in injection molding in function is, plastics from material toward type flow retardant force, to material speed rate and for material pressure 实.

        2. 塑化 pressure

         in injection in, pressure large small is screw design, products quality requirements and plastics types type different need 改变, if this and screw speed 都不变, increase pressure add strong/high function, improve/increase melt temperature degree, decrease small efficiency, increase large and 漏流, increase 驱动功 rate.

         in addition, increase pressure can make melt temperature degree uniform, color material mixed combined uniform and melt in gas 体. generally as in, pressure 决定应 in ensure products quality excellent front lower low good, its specific value is use plastics di color mold product types 而异, usually very less ultra- 20公斤/平方 cm.
