Automatic Integrated Hot Press 300x400mm 20 Ton Fast Heating

Product Overview

This automatic integrated hot press delivers 20 tons of force on 300×400 mm platens, providing 1.67 MPa unit pressure—ideal for high-density material processing. Its compact cabinet design houses a powerful hydraulic system and dual 6300W heating zones, ensuring fast cycle times and consistent results. The system combines advanced PID temperature control with programmable multi-step profiles, enabling precise ramping, soaking, and cooling.

An intuitive 7-inch touchscreen allows operators to easily set parameters, monitor real-time data, and store recipes for repeatable processing. Automatic pressure compensation adjusts for material relaxation, maintaining set force throughout the dwell. Engineered for reliability in lab and pilot production, this hot press features water-cooled platens for rapid cooling, safety interlocks, and rugged construction. Its modular design facilitates maintenance and future upgrades, while optional accessories like a dedicated chiller expand its capabilities for high-throughput environments.

Key Features

• Exceptional Unit Pressure (1.67 MPa): The 20-ton clamping force concentrated on the 300×400 mm platen area yields 1.67 MPa, which is nearly double the unit pressure of a typical large-format 20-ton press. This high-pressure capability enables the processing of materials that require intense compaction, such as ultra-high molecular weight polyethylene (UHMWPE) or carbon-carbon composites, and results in parts with superior mechanical strength and minimal porosity.
• Rapid 12.6 kW Dual-Zone Heating: Two independently controlled 6300W heating elements embedded in the upper and lower platens deliver the fastest heating in its class, reaching 300°C in under 15 minutes. Dual-zone control allows engineers to set different temperatures for each platen, enabling processes like heat-set curing with a cooler top plate or creating thermal gradients for specialized material behavior studies.
• Precision PID Programmable Control: The advanced multi-segment PID controller can store up to 20 process recipes, each with ramp, soak, and cool steps. Temperature accuracy is maintained within ±1°C, and the autotuning function dynamically adjusts PID parameters to optimize response for different thermal loads. Soft-start heating reduces thermal shock, while over-temperature alarms protect both the product and equipment.
• Integrated Water Cooling System: Both platens feature internal cooling channels that, when connected to a water source or optional chiller, can rapidly reduce temperature from 300°C to below 60°C in minutes. This quick cooling capability is essential for thermoplastics that require controlled quenching to lock in specific crystallinity levels, and it dramatically increases daily throughput by shortening mold release times.
• All-in-One Cabinet Construction: The self-contained design integrates the 20-ton hydraulic power pack, temperature controllers, and user interface into a single unit with a footprint of less than 1 square meter. Vibration-damping mounts and a rigid welded frame ensure stability during high-pressure cycles, while lockable casters allow easy relocation. This turnkey solution requires only electrical and water connections—no separate hydraulic hoses or external controllers.
• Touchscreen Automation & Data Logging: The 7-inch color HMI provides graphical display of temperature and pressure trends, recipe management, and alarm history. USB data export enables process traceability and quality documentation. Multiple user levels (operator, supervisor, administrator) ensure consistent process adherence and prevent unauthorized changes, meeting the requirements of regulated industries.
• Automatic Pressure Maintenance: The hydraulic system includes a pressure transducer and automatic pump cycling to compensate for leakage or material flow. This maintains the set force within tight tolerances, preventing the gradual pressure loss that can occur in simpler presses and ensuring uniform compaction across long dwell times.
• Safety-Certified Operation: Beyond the standard dual-hand start and emergency stop, the system features a transparent polycarbonate guard with magnetic interlocks that immediately halt movement when opened. All electrical components are CE and UL listed, and the hydraulic circuit includes over-pressure relief valves. An optional light curtain system provides additional operator protection for high-speed production environments.

Why Choose This Product

• Unmatched Pressure Intensity: With 1.67 MPa available, this press achieves densification levels that larger equivalent-tonnage presses cannot, making it ideal for high-performance composites and hard-to-press materials. The automatic pressure compensation ensures that set force is maintained regardless of material flow or relaxation, providing consistent part quality from the first cycle to the thousandth.
• Precision Engineering for Reproducibility: Dual-zone PID temperature control with ±1°C uniformity and programmable ramp/soak cycles guarantees that every batch meets exact thermal specifications. This level of control reduces scrap rates and supports rigorous scientific experimentation, while data logging and USB export enable comprehensive process documentation for quality audits.
• Built for Industrial Duty: The heavy-duty welded frame, premium hydraulic seals, and industrial-grade electrical components are rated for 24/7 operation in production environments. With minimal maintenance requirements—such as periodic oil changes and seal inspections—the system delivers years of trouble-free service, protecting your capital investment.
• Compact Footprint, Maximum Versatility: Unlike bulky multi-part systems, this integrated unit fits through standard doorways and operates on a standard 380V supply, making it practical for both university labs and factory floors. Its quick-change tooling concept allows adapting to various mold sizes, and the open frame design facilitates integration with automated loading/unloading systems.
• Responsive Global Support: Every unit comes with a comprehensive warranty and access to KINTEK’s application engineers for process optimization. From installation guidance and on-site training to custom mold design assistance, we ensure you get the most from your investment. Optional extended warranties and preventive maintenance contracts are available.
