2RT Plate Rubber Vulcanizing Press with Pull-Push Device
A heavy-duty, two-way sliding mold hydraulic vulcanizing press engineered for manufacturing large rubber products. Features dual-layer hot plates, high working pressure, and mold interchangeability for flexible, high-volume production.
Key Features & Specifications
Structural Design
- Frame & Platens: Fabricated from Q235 steel, shot-blasted, zinc-rich primed, and stress-relieved via machining
- Hot Platens: Dual-sizing 45# steel plates, normalized; equipped with automated electric steam valves and bypass for precise temperature control (steam/water switching capability)
- Platforms: Upper/lower platforms of Q235 steel, precision-welded using CO₂ shielded arc welding with alloy wire, followed by full furnace stress relieving to prevent deformation
Hydraulic & Actuation
- Cylinder Assembly: ZG270-500 cast cylinder with chilled alloy cast iron plunger
- Sealing System: Dual seals + integrated dust ring for extended service life
- Mold Movement: Front/rear sliding mold device supports hydraulic or mechanical actuation, capable of handling molds of any weight
Control System
- Automation: PLC-based full-automatic control for clamping, mold opening, exhaust setting, and manual override capability
Production Advantages
- Flexibility: Quick mold changeover for diverse rubber product lines
- Efficiency: Two working layers enable high throughput
- Precision: Camber-compensated rolls ensure uniform product thickness
Safety & Reliability
- Emergency stop system, bearing lubrication failure alarm, and robust construction for continuous industrial operation
Applications
Ideal for vulcanizing large-scale rubber products such as seals, mats, industrial components, and customized molded rubber items.
