20 Ton 500x500mm Split-Type Automatic Hot Press with Programmable PID Temperature Control

Product Overview

This split-type automatic hot press is a high-precision system engineered for the uniform processing of large-area materials under controlled heat and pressure. Combining a 500×500 mm hardened platen with a 20-ton hydraulic ram, the equipment is purpose-built for demanding laboratory and pilot-scale applications where consistency and repeatability are paramount. Its hallmark split design physically isolates the main press assembly from the digital control electronics, eliminating thermal cross-talk and ensuring uninterrupted performance in gloveboxes, cleanrooms, or fume hoods. This architecture also allows the press to be placed in gloveboxes or tight spaces without overheating sensitive equipment.

Targeting a diverse range of industries—from polymer and composite manufacturing to advanced battery research—this unit excels in processes such as sheet lamination, electrode calendering, and thin film pressing. The expansive working surface accommodates full-format substrates, multi-cavity tooling, or multiple small samples simultaneously, significantly boosting productivity while maintaining precise force distribution. The split design also simplifies maintenance and reduces downtime.

Built around a rigid welded frame and industrial-grade hydraulic components, the system is designed for years of heavy-duty operation. Intelligent features like PID temperature control with multi-step ramp-and-soak programming and automatic pressure compensation minimize the need for operator intervention, delivering process integrity even during extended production runs. Precision-ground platens guarantee parallelism under load, vital for producing flat, distortion-free panels. Routine calibration is simplified through built-in diagnostics, further reducing downtime. With its robust safety interlocks and optional water-cooling upgrade, this hot press represents a reliable, high-productivity solution for scaling up material development.

Key Features

• 500 × 500 mm Ultra-Wide Heated Platens: The large-format upper and lower platens provide an effective pressing area of half a square meter, enabling the processing of large-scale sheets, laminates, or multiple smaller samples simultaneously without sacrificing uniformity.
• Split-Type Thermal Isolation Architecture: The robust pressing column and hydraulic system are housed in a standalone mechanical frame, while all sensitive controllers, power modules, and operator interfaces reside in a separate, ventilated cabinet. This separation drastically reduces heat-aging of electronics, improving long-term reliability and safety.
• 7 kW High-Density Heating with PID Control: Calibrated cartridge heating elements embedded in both platens deliver rapid heat-up and sustained high temperatures up to 300 °C. A dual-channel PID controller with auto-tuning maintains setpoint accuracy to ±1 °C, compensating for thermal loads across the entire working area.
• Stepless Hydraulic Force Regulation (0–20 T): A servo-driven hydraulic pump provides infinitely adjustable pressing force with real-time feedback. The closed-loop control automatically compensates for material shrinkage or relaxation, holding the set pressure within a narrow tolerance throughout the dwell cycle.
• Programmable Multi-Step Process Cycles: The intuitive touch-screen interface allows users to create and store up to 20 recipes, each with configurable ramp rates, dwell times, temperature steps, and pressure profiles, enabling sophisticated process development.
• Superior Parallelism and Platen Rigidity: Precision-ground platens with a hardened surface finish maintain consistent parallelism under full load, critical for achieving uniform thickness in pressed parts and minimizing post-processing.
• Optional Recirculating Water Cooling: An integrated cooling upgrade circulates chilled water through the platen’s internal channels, rapidly bringing the press back to safe handling temperature and shortening cycle times in sequential production.
• Low Maintenance Hydraulic Design: Sealed circuits and high-durability seals minimize fluid leaks, while modular electrical components allow quick field replacement, reducing total ownership costs and downtime.
• Comprehensive Safety Features: Over-temperature alarms, emergency stop, platen guard, and automatic system cooling protect both operators and materials, ensuring compliance with laboratory safety protocols.
