25-Ton Automatic Laboratory Hot Press with Dual Programmable Heating Platens 250x250 mm CE Certified

Product Overview

This benchtop automatic hydraulic hot press is engineered for precision pressing and heating in laboratory environments. It delivers a maximum clamping force of 25 tons (250 kN) through an integrated hydraulic system, paired with dual independently heated platens that can reach 300°C. The system is controlled by a 7-inch full-color touchscreen, enabling fully programmable multi-stage pressure and temperature profiles. Ideal for polymer, composite, ceramic, and battery material research, this press ensures uniform heat distribution and repeatable results.

Its compact, upward-pressing design integrates all components, eliminating the need for external hydraulics or air supply, making it a space-efficient solution for demanding labs. Built with high-quality mold steel and stainless steel platens, and certified to CE safety standards, the unit provides reliable, long-term operation with minimal maintenance. The closed-loop pressure regulation and advanced safety features minimize operator error, ensuring every cycle meets specification even in continuous use.

Key Features

• Programmable Multi-Stage Control: The press is operated via a high-resolution 7-inch color touchscreen that offers an intuitive, icon-driven interface. Users can define up to 20 steps in a single program, each with independent setpoints for temperature ramp rate, target temperature, dwell time, pressure ramp rate, target pressure, and pressure hold time. This flexibility allows precise replication of complex thermal pressing cycles, making it ideal for research where process parameters must be strictly controlled and documented.
• Dual Independent Heating Platens: The upper and lower platens each incorporate high-density heating elements and separate thermocouple sensors, governed by advanced PID algorithms. This configuration ensures that the entire 250×250 mm platen area reaches the desired temperature quickly and maintains uniformity within ±1°C. Independent control enables asymmetric heating when required, or ensures both sides of the sample receive identical thermal treatment, eliminating common issues like warping or non-uniform curing.
• Integrated Hydraulic System: A compact, low-noise hydraulic power unit is built directly into the press base, eliminating the need for external compressors or large hydraulic packs. The system is designed for upward pressing, with the lower platen moving against a fixed upper platen. This arrangement simplifies sample loading and unloading, as the mold is placed on the moving lower platen. The hydraulic circuit includes precision valves for smooth, controlled motion and maintenance of constant pressure during the entire dwell period.
• Closed-Loop Pressure Regulation: Equipped with a high-accuracy pressure transducer, the controller continuously monitors the applied force and adjusts the hydraulic pump output in real time. This feedback loop compensates for material relaxation, thermal expansion, or minor leaks, ensuring that the set pressure is precisely maintained. Pressure ramp rates are fully programmable, allowing gentle force application for delicate samples or rapid loading for high-throughput testing, all within a ±0.5% accuracy band.
• CE Certified Safety & Comprehensive Alarms: The machine is designed and tested to meet CE directives for machinery safety, electromagnetic compatibility, and pressure equipment. Integrated safety features include a fixed upper platen shield, a polycarbonate safety door, emergency stop pushbutton, hydraulic over-pressure relief valve, and thermal fuses with software limits. In the event of an anomaly, audible and visual alarms alert the operator, and the system can automatically release pressure and shut down heating, providing extensive protection for both users and the instrument.
• Robust Benchtop Construction: The press frame is fabricated from thick-walled steel sections, precision-welded and stress-relieved to ensure long-term dimensional stability. The platens are machined from high-grade mold steel, heat-treated to a hardness of 50 HRC or higher, and double-disk ground to a mirror finish for flatness and parallelism. This durable construction resists deflection under maximum load and corrosive atmospheres, delivering reliable performance in heavy-use laboratory settings.
• Wide Daylight Opening: A 200 mm gap between the platens provides ample space for various mold assemblies, from thin film molds to tall compression dies. This generous opening facilitates easy mold handling and enables the pressing of multi-layered samples or tall components without disassembling the mold set, increasing operational convenience and throughput.
• Smooth Platen Movement: The lower platen traverses on precision linear bearings with a total stroke of 50 mm, driven by a hydraulic cylinder with controlled acceleration and deceleration. This ensures smooth, vibration-free movement during pressing and retraction, protecting delicate samples and extending mold life. (Note: For applications requiring specific stroke characteristics, please consult our technical team to confirm compatibility.)
• Compact Footprint: The press's integrated design consolidates the hydraulic power unit and control electronics into one enclosure, reducing the overall footprint to save valuable laboratory bench space. This space-saving layout is ideal for crowded benchtops, freeing up room for other essential equipment without sacrificing pressing capacity.
• Low-Noise Operation: The hydraulic pump and cooling components are acoustically damped to minimize noise during operation, typically below 65 dBA. This makes the press suitable for quiet laboratory environments where excessive noise could interfere with precision measurements or cause distraction.

Why Choose This Product

• Proven Long-Term Reliability: Designed and built for rigorous daily use, this press employs industrial-grade hydraulic components and temperature controllers that are known for durability. Many units have performed reliably for over a decade in research labs, requiring only routine oil changes and occasional seal replacements. This track record translates into a low total cost of ownership and minimal downtime.
• Precision Manufacturing for Consistent Output: The platens are precision-ground to a flatness of <0.05 mm and parallel within 0.02 mm, ensuring an even pressure distribution across the entire sample. Combined with the closed-loop pressure and temperature controls, this level of manufacturing precision minimizes sample-to-sample variation, a critical factor in research reproducibility.
• Comprehensive Safety and Certification: Beyond CE marking, the press integrates multiple redundant safety measures: a physical over-pressure valve, software temperature limits, an emergency stop, and interlocking guards. These features not only protect the operator but also safeguard the press against potential damage from overloading or overheating, providing peace of mind in high-stakes environments.
• Flexibility to Meet Diverse Needs: The generous platen size, wide daylight, and multi-stage programming capability make this press suitable for a vast array of materials and methods. Whether you are pressing thin films, thick composites, or delicate ceramics, the system adapts easily. For unique requirements, our team offers custom platen geometries, specialized control software, and integration with external systems.
