This series of plastic products used hydraulic cartridge valve integrated system. Suppression of movement in general as follows: slider fast, the slow down, slow suppression of molding (sometimes need to vent), pressure, pressure relief, micro-slider back, fast back to first limit, then the maximum slow the cylinder top, top of the cylinder Top speed, top of the cylinder to return, check materials and manual feed. Press the action constitutes a combination of high-low pressure pump, when in the fast downlink downlink from oil-filled self-respect to make up for the oil to achieve, thus greatly reducing the power required for the rapid phase. Repression in the top, the high and low pressure pump to participate in the work of the pressure reaches a certain value or after a post-set, low pump pressure relief, the work of high-pressure pump, so easy to suppress the formation of low-speed flow of materials and from the full cavity. This series of hydraulic components vulcanizer configuration of the main advantages, greatly improved the reliability of the product
