Dual-Station Servo Vacuum Hot Press: Taihe’s TH05YX-RZ-40T

Addressing a Real Production Bottleneck in Precision Bonding

Manufacturers working with wafers, plastics, leather, new materials, composite panels, phenolic resin, metallurgical powder, and new energy products routinely encounter a common operational constraint: different lamination and pressing processes often demand separate operations, and standalone station equipment limits continuous processing and capacity efficiency. On top of that, bonding and lamination require stable control of pressure, displacement, temperature, and holding time, while process quality and traceability require collected data for analysis and improvement—all without compromising operator safety.

Guangdong Taihe Machinery Equipment Co., Ltd., operating under the Taihe brand and headquartered at Weide Industrial Park, Building 2, No. 7 Weiziling East Road, Qingxi Town, Dongguan City, Guangdong Province, China, has built its equipment strategy around this exact pain point. The company’s stated industry insight is direct: precision product bonding and laminating require independent control of multiple pressing processes, stable pressure-displacement-temperature accuracy, process traceability, operator safety, and capacity efficiency. Its response is a line of servo-hydraulic hot press vacuum pressure equipment for precision mid-to-high temperature bonding, lamination, and curing.

The Core Product: 40T Dual-Station Servo Hot Press Vacuum Pressure Machine

The flagship unit addressing this market need is the 40T Dual-Station Servo Hot Press Vacuum Pressure Machine (Hydraulic Type), model TH05YX-RZ-40T, built as a dual-station, three-plate four-column hydraulic hot press with independent station process control. This configuration is specifically engineered for precision mid-to-high temperature bonding and lamination applications.

Dual-Station Independent Control for Continuous Operation

The defining architectural feature is dual-station independent control: each station independently sets and controls its own pressing process, which supports continuous operation across different pressing processes. This directly improves operating convenience and raises capacity efficiency—solving the exact limitation standalone station equipment presents in continuous production environments.

Precision Through a Full Closed-Loop Servo Hydraulic System

The machine runs on a full closed-loop servo hydraulic system that reduces the control valve loop and eliminates overflow, with a hydraulic system maximum debugging pressure of 20 MPa. The system automatically handles pressure and speed acceleration/deceleration along with torque-speed conversion, and the standby motor stops to save energy and reduce noise—directly preventing oil temperature and pressure overheating that would otherwise affect consistency.

This translates into measurable accuracy: system pressure accuracy of 1% F.S., displacement repeatability of ±0.02 mm, worktable flatness accuracy of ±0.008 mm, parallelism accuracy of ±0.02 mm, and temperature control accuracy of ±1°C. The temperature range spans room temperature to 380°C, with servo closing and mold opening speeds of 60 mm/s, and servo detection, pressing, and buffering speeds adjustable between 0.5–20 mm/s. Pressure holding time can be set anywhere from 1 to 999,999 seconds, giving operators fine control over process duration.

Thermal Engineering Built for Stability

Heating is delivered through far-infrared carbon fiber stainless steel heating rods with multi-point temperature sensing and PID control, paired with an imported high-quality hot-work die steel heating plate that undergoes high-temperature heat treatment and multiple tempering to remove thermal stress. This supports rapid heating and cooling, stable repeated operation, and reliable medium-temperature performance—critical for mid-to-high temperature bonding across the materials this equipment serves.

Structural Precision

The frame itself is computer-simulated for a lightweight four-column structure, machined through large high-precision CNC boring in a single pass so that flatness, parallelism, perpendicularity, and coaxiality meet industry and national inspection precision standards. Guide columns are Cr15 steel with high-frequency vacuum quenching, cylindrical grinding, and hard chrome plating, working alongside self-lubricating high-precision guide sleeves and high-precision linear bearings for vertical motion.

Data Traceability Built Into the Control System

Process quality and traceability are addressed through the PLC main control unit, which coordinates pressure, temperature, time, and vacuum degree parameters, operated via an HMI touch screen with process recipe storage and recall. The system can adjust, save, query, and call 100 sets of lamination process parameter recipes, with the ability to increase that number, and allows direct retrieval of a production serial number for a second mold loading.

On the data side, the system stores 200,000+ groups of lamination process records, with automatic collection, analysis, evaluation, and archiving. Each record captures date, number, shift, operator information, product name, lamination pressure, lamination position, and lamination result. Data acquisition runs at 300 Hz/s, adjustable to process requirements, and extraction is handled via USB drive in Excel format, supporting editing, querying, saving, and printing of reports. The HMI also provides a real-time dynamic curve display of lamination force versus time, with curve saving, querying, extraction, printing, and image capture.

Safety Architecture for Operator Protection

Given that operator safety requires coordinated mechanical, electrical, and light curtain protection, the TH05YX-RZ-40T integrates a safety light curtain, protective guard with an openable and removable guard door, fault alarm, mechanical limit, electrical limit, start button, emergency stop button, and floor anti-vibration feet. If any abnormal object enters the detection area during operation, the system triggers a buzzer alarm and either returns the servo to origin or stops it. Additional protections include overload and short-circuit protection switches, a buzzer alarm when temperature exceeds the set upper limit, and automatic inspection of unqualified lamination data with sound-light alarm and HMI alarm cause display.

Service and Delivery Support

Taihe’s service model covers equipment supply, on-site installation and commissioning, training, and warranty with after-sales repair. Training covers equipment structure, automatic and manual operation, function and process monitoring, and maintenance and fault elimination. Delivered documentation includes layout drawings, assembly drawings, electrical schematics, operation and maintenance manuals, consumable parts lists, test reports, and acceptance reports in both paper and electronic formats. The warranty runs 12 months from final acceptance, with quality-related parts replacement provided by the supplier during that period, and customer-caused damage receiving free technical service while parts and consumables are charged separately.

Industry Fit

This technical specification applies to industries including precision products, wafers, plastics, leather, new materials, composite panels, phenolic resin, metallurgical powder, and new energy products—all of which rely on cold/hot lamination, bonding, and curing processes where pressure, displacement, and temperature stability directly determine output quality. For organizations evaluating a dual-station servo vacuum hot press, the TH05YX-RZ-40T presents a documented combination of independent-station flexibility, closed-loop hydraulic precision, and built-in data traceability suited to demanding bonding and lamination workflows.
