25 Ton Automatic Laboratory Hot Press with Dual Heated Platens and Precision Control

Product Overview

This benchtop automatic hydraulic hot press delivers industrial-grade performance in a compact, laboratory-friendly format. Engineered for precise compression molding and sample preparation, the system integrates a 25-ton hydraulic press with 200×200 mm independent dual-heated platens, capable of reaching temperatures up to 300°C. The advanced closed-loop control architecture combines a high-resolution touchscreen PLC with multi-segment pressure and temperature programming, enabling complex thermal-mechanical profiles with exceptional repeatability. From polymer melting and curing to composite consolidation, every cycle is executed with consistent force distribution and thermal uniformity, thanks to precision-ground mold steel platens and a rigid cast-iron frame.

This versatile instrument is indispensable across materials science, quality assurance, and small-scale production laboratories. Polymer scientists rely on it for fabricating standardized test specimens for tensile, impact, and thermal analysis. In rubber technology, it accurately vulcanizes compounds to evaluate cross-linking behavior. Composite engineers use it to consolidate fiber-reinforced laminates under precisely controlled conditions, while battery researchers apply it for electrode preparation and solid-state electrolyte pressing. The ability to program multi-step pressure ramps, temperature gradients, and timed holds makes it equally suited for hot embossing, lamination, and thin-film fabrication, where process precision directly impacts product quality.

Operational safety and durability are central to the design. The fully transparent acrylic enclosure provides a clear view of the pressing process while automatically interrupting operation if opened, preventing accidental contact with hot surfaces. Redundant over-temperature and over-pressure protection circuits safeguard both the user and the equipment. The low-noise hydraulic power unit and upward pressing mechanism minimize workspace disruption, while the water-cooled platens enable rapid turnaround between cycles. With its robust construction and CE certification, this press is built to deliver consistent, safe performance year after year in demanding laboratory environments.

Key Features

• Precision Closed-Loop Pressure Control: Adjustable force from 0.1 to 25 tons with multi-segment programmable holding and ramp rates ensures excellent process repeatability for demanding molding applications. The closed-loop system continuously monitors and adjusts hydraulic pressure, compensating for any drift and maintaining the setpoint within tight tolerances throughout the entire press cycle.
• Independent Dual-Zone Heating: Two microprocessor-controlled heated platens, each measuring 200×200 mm, deliver temperatures up to 300°C with programmable slope control. This dual-zone architecture allows independent setting of upper and lower platen temperatures, enabling tailored thermal gradients for specialized processes like asymmetric heating or controlled cooling of multilayer structures.
• Integrated Water Cooling System: Built-in cooling channels within the platens facilitate rapid heat dissipation after the molding phase. By connecting to a lab water supply or optional recirculating chiller, operators can drastically shorten cycle times and improve throughput, particularly when processing temperature-sensitive materials that require quick quenching to retain amorphous or fine-grained microstructures.
• Advanced Safety Interlock: The high-strength transparent acrylic safety shield fully encloses the pressing area and is interlocked to immediately halt platens if the shield is opened during operation. This meets CE safety requirements and provides a critical barrier against accidental burns or pinch injuries, while still offering full visibility for teaching and process observation.
• Intuitive 7-Inch Touchscreen Controller: At the heart of the system is a full-color PLC interface that simplifies complex process programming. Users can define multi-step sequences for pressure, temperature, and time, store an unlimited number of recipes, and monitor real-time data. The large display reduces operator error and accelerates training, making sophisticated programming accessible even to technicians with minimal experience.
• Robust Low-Noise Hydraulic System: The self-contained hydraulic power unit operates with minimal acoustic footprint, suitable for open-plan laboratories. Its upward-pressing design enhances mold alignment and safety, while the high-capacity pump ensures rapid closure and responsive pressure adjustments. The system is sealed for clean operation, with no risk of oil leaks in the workspace.
• Flexible Global Compatibility and Configuration: The press is available in both 220V/50Hz and 110V/60Hz power configurations (with heating power adjusted accordingly), and can be customized in terms of daylight opening, stroke, and heating wattage. Optional accessories such as a standalone water chiller, additional platen sizes, and integration with gloveboxes for inert atmosphere processing extend its functionality to meet diverse research needs.
