Taihe Desktop Servo Hot Press Vacuum Machine: Key Parameters

Guangdong Taihe Machinery Equipment Co., Ltd., operating under the Taihe brand and headquartered in Building 2, Weide Industrial Park, No. 7 Weiziling East Road, Qingxi Town, Dongguan City, Guangdong Province, China, positions itself as a supplier of desktop servo hot press vacuum equipment for research, development, and medium-to-high-temperature bonding processes. The company was formed around a clear industry pain point: precision bonding applications involving glass, silicon wafers, sapphire, quartz, batteries, new materials, composite boards, wood, phenolic resin, metallurgical powder, and new energy products require controlled pressure, temperature, vacuum or inert atmosphere, repeatability, and traceable process data—all within a laboratory-friendly footprint.

Understanding the  Desktop Servo Hot Press Vacuum Pressure Machine

Within Taihe’s desktop servo hot press vacuum machine line, the flagship model is the Desktop Servo Hot Press Vacuum Pressure Machine (Electric Cylinder Type). This is a  desktop servo press that integrates heating, vacuum, and inert gas capability for controlled bonding, lamination, and pressing of precision materials. It is built on a three-plate four-column structure, which provides a stable pressing structure suited to desktop use, and it uses heat-treated stainless steel hot press plates that undergo multiple tempering after high-temperature heat treatment to remove thermal stress and improve plate performance.

The machine is designed for laboratory research, medical process research, new material research, and lithium battery research, addressing the need for regulated pressure, position, speed, temperature, vacuum, and data traceability during bonding of glass, silicon wafers, crystal wafers, sapphire, quartz, batteries, new materials, composite boards, wood, phenolic resin, metallurgical powder, and new energy products.

Core Technical Parameters

The technical specifications published by Taihe cover a wide range of operational metrics:

• Worktable surface treatment: As required
• Pressure setting resolution: 0.1 kg
• Displacement setting resolution: 0.001 mm
• System pressure accuracy: 0.1% F.S.
• Displacement repeatability: ±0.02 mm
• Worktable flatness accuracy: ±0.008 mm
• Parallelism accuracy: ±0.02 mm
• Temperature control accuracy: ±1°C
• Inert gas charging: Supported
• Speed setting resolution: 0.001 mm
• Pressure holding time: 1–999999 s
• Data export format: Excel
• Data extraction method: USB drive
• Data extraction frequency: 300 Hz/s, adjustable according to process requirements
• Operation types: Automatic / manual
• Operation method: Touchscreen / dual-button start
• On-site power supply: Three-phase, AC380V ±10%, 50 Hz
• Production environment: Ambient temperature room temperature to 40°C; humidity 0–90%

These parameters are governed by a PLC as the main control unit coordinating pressure and time parameters, an HMI touchscreen for operation, recipe storage, and process monitoring, and a closed-loop servo electric cylinder drive. The closed-loop servo electric cylinder is what allows the machine to reach 0.1% F.S. system pressure accuracy and ±0.02 mm displacement repeatability, which together support consistent bond quality across repeated cycles.

Structural and Thermal Engineering

Beyond the published parameter table, the machine’s construction directly supports these figures. The frame design relies on computer data simulation for a lightweight four-column structure, machined by large-format high-accuracy CNC boring to meet industry and national inspection accuracy standards for flatness, parallelism, verticality, and coaxiality. The platen material is imported special quality die steel plate, chosen for good hardenability, low deformation rate, high rigidity, and long service life. The guide columns are made of Cr15 quality round steel with high-frequency vacuum quenching, outer cylindrical grinding, and hard chrome plating, delivering tensile strength, wear resistance, and rust prevention. The guide system itself uses self-lubricating high-accuracy guide sleeves and high-accuracy linear bearings to support vertical motion accuracy and stability.

On the thermal side, IR far-infrared carbon fiber stainless steel heating rods with PID control deliver the ±1°C temperature control accuracy noted above, while multi-point temperature sensing windows monitor zone temperatures in real time. Internal flow channels in the hot press plate enable uniform distribution and rapid cooling, supporting fast product setting through PID temperature control. Upper and lower mold heating can be controlled independently, and vacuum can be controlled independently, giving operators flexibility across different bonding processes.

Data Capabilities and Process Traceability

A defining aspect of this machine’s parameter set is its data capacity: the system supports 200,000+ groups of pressing data, collected at 300 Hz/s. It automatically collects, analyzes, evaluates, and archives date, serial number, shift, operator information, product name, pressing pressure, pressing position, and pressing result. A real-time force-time dynamic curve is displayed on the HMI, with curve image capture and Excel report export via USB for editing, querying, saving, and printing. On the recipe side, the HMI can set, save, query, and recall 100 pressing process parameter recipes, with recipe count expandable according to requirements, allowing direct production sequence recall after die installation. Multi-stage control also permits setting multiple pressure, stroke, and speed segments according to process requirements.

Safety and Control Systems

The parameter list is paired with a set of safety and monitoring functions. These include a safety light curtain with full guarding and interlock—if any object is detected in the light curtain area during operation, the system alarms and the servo returns to origin or stops. Additional protections include overload protection switch, short-circuit protection switch, buzzer alarm when temperature exceeds the set upper limit, mechanical and electrical limits, dual-button start, and an emergency stop button. The system also self-checks press data and operating abnormalities, triggering sound/light alarms with HMI alarm reason display when pressure or position values fall outside set limits. An I/O monitoring window allows real-time monitoring of communication port states for rapid fault location, and reserved input/output communication ports allow connection with other equipment.

Service and Delivery Support

Taihe’s service model includes equipment supply with on-site installation, commissioning, operator training, and maintenance training, covering technical guidance, equipment structure training, automatic and manual operation training, function and process monitoring training, and maintenance and fault elimination training. The company offers a 2-hour response after service request and a 12-month warranty from final acceptance, replacing components damaged by quality issues; for damage caused by improper buyer operation, technical service remains free while parts and consumables are charged separately. Documentation delivered includes layout drawings, assembly drawings, and electrical schematic diagrams, an equipment operation and maintenance manual, a consumables list, and test and acceptance reports, all provided in both paper and electronic form.

Industry Adaptation and Customer Validation

This desktop servo hot press vacuum pressure machine has been referenced by Chongqing Zhongbin Technology Co., Ltd., reflecting its use across laboratory research, medical process research, new material research, and lithium battery research settings. Its combination of ±1°C temperature control, 0.1% F.S. pressure accuracy, 100-recipe storage, and 200,000+ group data logging positions it as a parameter-driven solution for teams that need repeatable, traceable pressing and bonding results across a broad range of precision materials.
