high precision injection molding mold and high control degree injection molding machine is obtain 漂亮, precision automotive injection molding parts necessary conditions,而 injection molding machine control degree also main/primary in in for it clamping force and injection degree control. is introduction tool has 里程碑意义 injection molding machine clamping force 自动纠 positive and PPC high property can injection molding processing 两 large technology.
automotive parts in inner, outer trim parts in positive 占据 越 越 important 位, it precision degree in certain types upper table/sheet 轿车 档次. remove its or temperature outer decoration outer, it skeleton/framework —— injection molding parts precision degree 起 决定 property function.

need obtain 漂亮, precision automotive injection molding parts, not only need has high precision injection molding mold, also must has control degree relatively high injection molding machine, injection molding machine control degree also main/primary in in for it clamping force and injection degree control. and Japan injection molding machine manufacturing enterprise in this research from 就不遗余 force, currently, technology 远远领先于国 inner enterprise.

in has this technology research and application in, in 20世纪90 year 代初期 and in 期 两 large technology, tool has 里程碑 意义, this is clamping force 自动纠 positive and PPC（Pack Pressure Control） high property can injection methods.

一台 tool has clamping force 自动纠 positive function injection molding machine, and machine different in 于: it can amount to due to mold temperature degree rise high and other outer causes belt/tape clamping force 变化, through machine and adjustment machine 构, for clamping force 进行自动纠 positive, let it to setting 位置, make machine can 够始终 in clamping force ring lower as. this function benefits is easy 见, 首先, it can in clamping force ensure products outer degree, anti flash and other defect 出现; its 次, for machine and mold has very good function, especially for machine force parts, 诸如拉杆 and sheet/plate degree maintain and long lifespan large has 裨益.

PPC high property can injection methods is types new type injection to holding pressure control methods, it features in through testing injection 油缸 油 pressure, testing mold type pressure, from control injection to holding pressure 转换. versus for/regarding 传统 位置 and time control, PPC control can 够避免 due to amount and amount generate defect and various dry factors products defect, ensure stability formed quality. it can will injection pressure use table/sheet 形式显示 in PDP画面 upper, therefore can positive 确, speed provide most formed conditions, application this technology can very add holding pressure ring control 程序.
