国内外注塑机液压系统现状及其发展趋势──兼论二通插装比例控制技术在注塑机中的应用

PRESENT SITUATION AND DEVELOPING PROSPECT OF HYDRAULIC SYSTEM OF PLASTIC INIECTION MOULDING MACHINE IN CHINA AND THE WORLD ──and Application or 2─way Throttle Proportional Control Technologe in The Plastic Injection Moulding Machine

本文叙述了注塑成型工艺对液压系统的要求，注塑机液压系统的分类和比较；并着重论述了具有八十年代世界先进水平的二通插装比例问的结构和特点及其在注塑机中的应用。

This paper narrates that the technological process of injection moulding puts in a claim for the hydraulic systems. The hydraulic systems of plastic injection moulding machine are usually classified and compared. It expounds emphatically structure and property of 2-way proportional throttle cartridge valve has caught up with the world's advaned level in the eighties. The2-way proportional throttle cartridge valve being used in plastic injection moulding machine.
