    Performance characteristics:

    1. The machine body is made of high-quality steel plate, CNC cutting, CO2 welding structure, with good overall rigidity and beautiful appearance; The machine body adopts trolley type electric furnace annealing or vibration aging to remove stress, and the deformation is small.

    2. The crankshaft is placed longitudinally with short fulcrum distance, compact structure and reasonable layout.

    3. The transmission gear is immersed in oil in the gearbox and the gear surface is grinded. The transmission noise is low and the wear is small.

    4. Pneumatic friction clutch brake, mechanical interlock, safe and reliable, low noise, and friction plate is not easy to wear; Domestic clutch of Shanghai "Dingjie" brand or Italian "OMPI" brand shall be selected; The wet clutch is also provided according to the special needs of users.

    5. The imported pneumatic external hydraulic overload pump is selected, with sensitive action, good stability and convenient maintenance.

    6. The slider guide rail adopts six side guidance, with long guide rail and high operation accuracy.

    7. The lubricating system adopts imported electric grease pump for automatic fixed-point lubrication, and is equipped with a progressive distributor. The oil supply time and amount are controlled by the PLC system, and the oil circuit is blocked for automatic alarm indication.

    8. The height adjustment of the slide block mold installation is convenient for use, and it is equipped with a digital mold height indicator with a display accuracy of+0.1mm. (Note: Manual adjustment is used below JH21-45 type, and electric adjustment is used above JH21-60 type).

    9. The electrical system is controlled by French "Schneider" brand and Japanese "Hequan" programmable logic controller (PLC), with stepless speed regulation of stroke times and emergency stop, inching, single and continuous operation modes; The main electrical components are French "Schneider" brand, with reliable performance.
