HENCH Vertical Automatic Heating Press: Precision Hot-Pressing Sample Preparation Solution for Laboratories

In the research and development of polymers, composite materials, rubber-plastics, and new functional materials, hot-press forming is a critical step in sample preparation. Conventional hot-press equipment commonly suffers from large temperature control deviation, obvious pressure fluctuation, considerable manual interference, and poor sample repeatability. These drawbacks readily lead to sample defects such as air bubbles, warpage, and uneven thickness, which directly compromise the reliability of physical-chemical tests and spectral analysis.

Developed for real-world laboratory requirements, the HENCH hydraulic press series products integrates precise temperature control, fully automatic hydraulic drive, and intelligent program control, delivering stable and efficient hot-press sample preparation for universities, research institutes, new-material enterprises, and pharmaceutical and chemical laboratories.

High-Rigidity Hardware Structure for Uniform Force and Precise Parallelism

The machine adopts an integrated vertical four-column structure with high rigidity and outstanding pressure-bearing capacity, ensuring minimal deformation during operation and good parallelism of upper and lower heating plates. This hardware design effectively avoids uneven stress on samples.

Equipped with a closed-loop PLC temperature control system, it offers two temperature ranges: room temperature to 300 °C and room temperature to 500 °C, with a temperature accuracy of ±0.1 °C. The upper and lower heating plates are controlled independently, and the surface temperature difference is kept within ±1 °C. High-efficiency thermal insulation reduces outward heat transfer and protects both operators and the machine.

30-Segment Programmable Profiles for Complex Experimental Curves

Up to 30-segment programmable profiles are available. Users can customize complete process curves including staged heating, constant-temperature holding, pressure holding, pressure relief, and cooling. It adapts to complex experimental procedures such as melt plasticization, cross-linking curing, and laminated composite pressing:

• For temperature-sensitive materials, it faithfully reproduces experimental conditions.
• It reduces sample defects and guarantees consistent micro-structures.

Fully Automatic Electro-Hydraulic Drive to Eliminate Human Error

Its pressure system adopts a fully automatic electro-hydraulic drive to eliminate manual operation. Pressure output is smooth and highly accurate, supporting programmed pressure rise, multi-stage pressure holding, and automatic pressure relief with freely adjustable holding time.

• Real-time pressure conversion: Displays actual force applied to samples, eliminating human-induced errors and greatly improving experimental reproducibility.
• 7-inch color touch screen: Supports Chinese-English switching. Parameters are easy to configure, and full hot-press cycles run with one-click operation, lowering operational barriers.
• Water-cooling module (optional): Enables rapid cooling after tests to shorten experimental cycles and boost laboratory efficiency.

Comprehensive Safety Features and Wide Applications

• Multi-layer protection: Includes emergency stop, over-temperature alarm, over-pressure overload protection, and travel limit safeguards to mitigate hazards under high-temperature and high-pressure conditions.
• Mold compatibility: Compatible with various hot-press molds (round and square). Worktable dimensions can be customized for different specimen sizes.

Typical Applications: Polymer blending, rubber vulcanization, plastic film forming, composite lamination, and functional-material hot forming. Prepared specimens are suitable for tensile testing, rheological analysis, FTIR sample preparation solutions, and other characterization tests.

Delivering performance comparable to imported counterparts, this domestic precision equipment balances accuracy, stability, and practicality. It helps researchers overcome hot-pressing challenges to obtain highly consistent samples and provides solid hardware support for materials-science research.
