This series of plastic products used hydraulic cartridge valves integrated system. Suppression of action generally: slider fast, the slow down, slow Pressing (sometimes need to vent), holding pressure, pressure relief, micro slide back, fast back to first limit, slow ejection tank top, top of the cylinder Top speed, ejecting cylinder back, hand to take material and feeding. Press the action constitutes a combination of high and low pressure pump, in the fast down by the weight down when the oil-filled, fill oil to achieve, thus greatly reducing the power required for the fast phase. In the top of repression, the high and low pressure pumps involved in the pressure reaches a certain value or a post set, the low pressure pump relief, high-pressure pump working, so easy to suppress the formation of low material flow and discharge the full cavity. This series of hydraulic curing major component configuration is superior, greatly improve the reliability of the product
