    Function Features

    • The oil cooler regulates oil temperature and maintains internal thermal balance, preventing unstable expansion caused by temperature fluctuations. This minimizes frame deformation and enhances BDC stability.
    • The frame structure is optimized through finite element analysis (FEA) for rationalized design.
    • High-strength cast iron frame undergoes annealing, rough machining and vibratory stress relief (VSR), thoroughly eliminating thermal stresses to ensure long-term precision.
    • Centralized crank center lubrication eliminates swinging oil pipes, reducing breakage risks.
    • Temperature-controlled oil cooling minimizes press thermal deformation.
    • Tailored counter dynamic balancing system ensures stability during high-speed operation by compensating for upper die rebound.
    • Gantry-type frame structure minimizes deflection during stamping compared to C-frame presses.
    • Hydraulic slide locking/releasing device ensures press operation safety and enables easy die adjustment.
    • Electric die height adjustment with position indicator enables easier operation.
    • The PLC interface microcomputer control system or mobile console displays press angle, speed, and error message.
