Air Spring Rubber Vulcanizing Press

• The rubber vulcanizing press adopts a column-type structure. The main components include: Four columns, main hydraulic cylinders, upper and lower frames, heating plates, thermal insulation plates, hydraulic power unit, steam control system.

  

• Both upper and lower heating plates are equipped with single-sided T-slots. T-slot layout: X-type structure, size M20.
• Upper and lower frames are fabricated from Q235-B steel plates. To ensure accuracy, the press adopts features including automatic cutting for material preparation, welding grooves machined by planer, CO2 gas-shielded welding with alloy welding wire. Welding stress is fully relieved to prevent deformation during long-term operation, ensuring structural stability and product quality.

  

• Heating plates are manufactured from double-fixed-length rolled Q235 steel plates, with a surface roughness of Ra 1.6. Each heating plate is designed with one independent heating zone. Internal steam channels are optimally arranged with a spacing of 70-90mm. Manual ball valves are installed at both ends of each metal hose to facilitate replacement and reduce steam leakage during maintenance.
• A 20mm thick thermal insulation layer is installed on the top of the upper heating plate and the bottom of the lower heating plate.
  Insulation material: asbestos-free resin insulation board
  Pressure resistance: ≥400kg/cm²
  Thermal conductivity: 0.33W/m·K
  Temperature resistance: 220-250℃
  This design ensures effective heat insulation, reduced heat transfer losses, long-term resistance to local compression deformation and a service life of more than 8 years under normal operating conditions.

  

• The hydraulic system is designed according to process requirements and motion sequences. Equipped with safety relief valves and multi-level pressure monitoring, the system ensures operating pressure within the maximum allowable limit. Cartridge valves or manifold-mounted valves are used for easy maintenance and reliable sealing performance.
• Electrical control system features a PLC+touch screen control system, with bilingual operation interface available in Chinese and English. The touch screen displays and records: Vulcanization pressure, heating plate temperature, vulcanization temperature-pressure curves, historical curves, temperature and pressure alarm information, vulcanization time, exhaust time and exhaust cycles. This configuration enables intuitive operation, precise control, and full process traceability.
