Y71 series plastic hydraulic press

Plastic product compression molding is divided into the molding of thermosetting materials and the molding of thermoplastic materials. Such as phenolic plastics in the electrical industry. Such as polytetrafluoroethylene plastic in the daily necessities industry. Changing the control program can also suppress friction materials in the automotive industry, such as brake pads. This series of plastic product hydraulic material machines adopts a plug-in valve integrated system, and the electrical appliances are controlled by PLC programmable logic controller. The pressing actions are generally: slide block fast down, slow down down down, slow pressing molding (sometimes requiring exhaust), pressure holding, pressure relief, slide block micro return, fast return to upper limit, ejection cylinder fast ejection, ejection cylinder retraction, manual material retrieval and feeding. The action of the press is composed of a high and low pressure combination pump, which, when rapidly descending, self weight descends to flush and replenish oil, thus greatly reducing the power required in the fast stage. During rapid pre pressing, both high and low pressure pumps are involved in the operation. When the pressure reaches a certain value or is pressed to a certain set position, the low pressure pump releases pressure, while only the high pressure pump works. This forms low-speed compression, facilitating sufficient material flow and gas discharge from the mold cavity. The superior configuration of the main components in this series of hydraulic presses greatly improves the reliability of the product. If the hydraulic components use products from Beijing Hydraulic Parts Factory, the thermocouples are also branded products. Our company can manufacture specialized press machines that are widened and raised according to user requirements.
