注射压力(MPa):

1、注射压力,很多人会将该参数误认为是注射时油缸所受到的液压系统压强;其实并非如此,注射压力一般指注塑机在注射时,

熔融原料注入模腔时在料筒内所受到的单位面积的压强,单位为MPa。

2、前者说的载体是在注射时注射油缸里的液压油;而正确的应该是载体为在注射时料筒内熔融物料。

3、此两者数据完全不同,达数倍的相差,其倍数计算一般为:注射油缸面积/螺杆直径截面积。

Injection pressure (MPa) :

1. Injection pressure, many people will mistake this parameter for the hydraulic system pressure suffered by the cylinder during injection; Actually, it's not. The injection pressure usually means that when the injection machine is injected,

The pressure per unit area of the cylinder on which the molten material is injected into the mold cavity, unit is MPa.

2, the former said that the carrier is in the injection of hydraulic oil in the cylinder; The correct carrier should be the molten material in the cylinder during injection.

3, the two data are completely different, up to several times the difference, the multiple calculation is generally: injection cylinder area/screw diameter cross-sectional area.
