91 塑料制品压制成型分为热固性材料的成型呵热塑性材料的成型。本系列塑料制品液压机采用插装阀集成系统，电器采用PLC可编程控制。
性能特点
计算机优化结构设计，三梁四柱式结构，简单、经济、实用。液压控制采用插装阀集成系统，动作可靠，使用寿命长，液压冲击小，减少了连接管路与泄漏点。独立的电气控制系统，工作可靠，动作直观，维修方便。采用按钮集中控制，具有调整、双手单次循环两种操作方式。通过操作面板选择，可实现定程、定压两种成型工艺，并具有保压延时等性能。工作压力，行程根据工艺需要在规定范围内可调。
Computer optimized design，3-beam &4-colum compact structure, with high performance cost ratio cartridge vavle intrgrated unit equipped in hydraulic contral by means of proper piping and minimum hydraulic impact design.
Independent electrical control system is adopted in the press adjustment and TWO-hand/single cycle operation mode at operator’s choice preset stroke forming process or preset pressure forming process can be selected on control panel; pressure holding period can be preset ording to requirements stroke and pressure can be sdjusted with in specified scope.
