Benchtop Automatic Vacuum Hot Press for Advanced Material Processing

Product Overview

This advanced benchtop automatic vacuum hot press is engineered for precision thermal pressing in materials research and small-scale production. Integrating a robust 25-ton automatic hydraulic cylinder, dual programmable heated platens, and a chemical-resistant oil-free dry vacuum chamber, the system enables highly repeatable pressing cycles under controlled inert atmospheres. The intuitive HMI touchscreen not only simplifies complex multi-stage programming but also provides real-time calculation of actual sample contact stress (MPa) based on the input die diameter, ensuring precise process documentation and scalability.

Target industries include solid-state battery R&D, where vacuum and heat are critical for bonding electrolyte layers without contamination; polymer and composite lamination for electronics packaging; and analytical laboratories preparing high-purity pellets for spectroscopy. The unit’s compact benchtop footprint and robust construction make it suitable for both academic labs and industrial pilot lines requiring continuous operation.

Its oil-free vacuum pump eliminates the risk of hydrocarbon backstreaming, safeguarding sensitive samples and reducing maintenance. With integrated safety features and CE certification, this press delivers consistent performance run after run, supported by a design that prioritizes operator safety and long-term reliability.

Key Features

• Fully Automatic Multi-Stage Pressurization: The system supports unlimited programmable steps for auto-pressurization, pressure holding, precision compensation, and timed decompression. Operators can define complex multi-step profiles with stage-specific durations and pressures, from as low as 0.3 tons up to the maximum 25 tons, with a force resolution of ±0.01 tons. This level of control ensures exact replication of process parameters for materials that require gradual or stepped pressure application, such as layered composites or delicate battery films.

• Smart Real-Time MPa Stress Display: Instead of manually calculating contact stress, simply input the die or mold diameter via the touchscreen. The HMI instantly converts the applied force into MPa, displaying real-time stress on the sample. This feature is invaluable for standardizing protocols across different die sizes, enabling direct comparison of experimental conditions and supporting publication-quality reporting.

• Oil-Free Chemical-Resistant Vacuum System: The included electric dry vacuum pump delivers a clean vacuum of -0.1 MPa (gauge) without oil. This prevents any risk of oil vapor contamination in sensitive materials like solid-state electrolytes or high-purity ceramics. Additionally, maintenance costs are reduced since there is no pump oil to change or dispose of, and the chemical-resistant construction withstands corrosive off-gassing.

• Dual Large-Area Heated Platens with Precise Temperature Control: Each platen measures 180 mm × 180 mm, providing a generous working area for pressing multiple samples or large-area films. Temperature is controlled via a programmable multi-segment PID loop with 0.1°C resolution, achieving uniformity from room temperature up to 300°C (and beyond, with certain configurations). Symmetrical top-and-bottom heating ensures minimal thermal gradients across the sample for consistent lamination or densification.

• Comprehensive Safety Protection: Two independent safety systems protect both equipment and operator. Mechanical overpressure protection automatically releases hydraulic pressure if the safe limit is exceeded, while a dedicated emergency stop button immediately halts all motion. Additionally, the HMI triggers a visual "Caution: Hot Surface" alert whenever platen or mold temperatures exceed 50°C, reducing the risk of burns.

• Compact Benchtop Architecture: Despite its 25-ton capacity, the press is designed for benchtop installation, saving valuable floor space in crowded laboratories. The ergonomic layout places the work area and controls within easy reach, and the integrated vacuum chamber eliminates the need for external glovebox connections in many cases.

• Expandable with Custom Tooling and Cooling: Optional forced-air cooling or external water recirculating chillers can be added to accelerate cycle times. Custom high-hardness heated dies in various sizes are available for specific applications, extending the system’s versatility for prototyping and small-batch production.

Why Choose This Product

• Engineering for Long-Term Reliability: Heavy-duty steel framework, premium hydraulic components, and industrial-grade heating elements are tested for continuous operation. The oil-free vacuum pump eliminates the most common maintenance headache—oil changes—and the chemical-resistant design withstands aggressive outgassing from polymers or electrolytes. Backed by rigorous factory testing, this press is built to deliver consistent performance over thousands of cycles.

• Class-Leading Precision: Digital servo-hydraulic control with real-time feedback ensures force accuracy within ±0.01 tons. The multi-segment temperature controller maintains uniformity across the entire platen surface, with actual sample stress displayed in MPa for direct correlation to published data. Such precision is critical when optimizing pressing parameters for novel materials.

• Safety-First Design: Beyond CE compliance, the press incorporates multiple safeguards: automatic pressure release on overload, emergency stop, and a visual high-temperature alert on the HMI when surfaces exceed 50°C. These features protect operators and prevent damage to expensive tooling, making it suitable for multi-user lab environments.
