Multiple layers hydraulic press for friction material

Corresponding parameter set not found, please add it in property template of background

This series of hydraulic press adopts three-beam four-column structure with long stroke. Multiple layers for pressing are mounted above the sliding block. Several sets of mold are working at the same time by fixing on the layers, which greatly improve the production efficiency. The press is mainly suitable for cold or hot forming process of friction materials. The structure is optimized by computer aided design, with attractive appearance, high rigidity, and good cost ratio. Cartridge valve integrated unit equipped in hydraulic control system, with high reliability, durability. Oil leakage is avoided by means of proper piping and minimum hydraulic impact design. Electrical system adopts the centralized button control based on PLC. Two operation modes of adjustment and two-hand single cycle are available for selecting. The mold temperature is controlled by the intelligent PID system, with the advantage of high accuracy, long service life, and insensitive to heating power. According to the requirements, stroke and pressure can be adjusted within specified scope. It can realize the fixed stroke and fixed pressure forming processes.
