Hot Press Machine

As a premier technology-driven enterprise established in 2017, Cooling-Thermal Co., Ltd. specializes in the R&D and manufacturing of automated thermal management equipment. Our high-performance Hot Press Machines are engineered to meet the rigorous demands of Vapor Chamber (VC) and Heat Pipe production, ensuring superior structural integrity and thermal conductivity.

Custom Industrial Heat Press Equipment for VC & Heat Pipe Assembly

The hot press machine is used in the heat pipe production line after tube sealing and before pipe bending — shaping the sealed, fluid-filled heat pipe into the flat or profiled geometry required for integration into CPU coolers, server heat sinks, laptop thermal modules, and vapor chamber assemblies. The forming process uses hydraulic pressure applied through precision hot forging dies (standard model) or cold forging dies (heavy-duty model), with controlled heating to ensure the copper tube material reaches the optimal forming temperature for consistent dimensional output without cracking or wall thinning beyond specification.

Key Specifications

Heavy-Duty Model (15-ton)

Advantages of the Hot Press Machine

1. ±0.05mm Pressing Tolerance — Production-Grade Dimensional Control
The heavy-duty 15-ton model achieves a pressing tolerance of ±0.05mm — a level of dimensional precision that directly determines whether the flattened heat pipe fits the contact surface geometry of the thermal solution assembly it is designed for. In CPU coolers, server heat sinks, and laptop thermal modules, the contact surface of the flattened heat pipe must match the mating surface within tight tolerances to maintain effective thermal interface conductance. ±0.05mm tolerance at the hot press station is what ensures this contact geometry is consistent across every unit in a production batch.

2. Dual-Model Range — 10-Ton Standard and 15-Ton Heavy-Duty
Cooling-Thermal offers two hot press machine configurations to match different production requirements. The standard 10-ton model with ±0.25mm planar accuracy and hot forging dies covers the majority of standard copper heat pipe flattening applications. The heavy-duty 15-ton model with ±0.05mm pressing tolerance and cold forging dies handles applications requiring higher forming force or tighter dimensional control — including large-diameter pipes, thick-wall heat pipes, and thermal solution assemblies with precise contact geometry requirements. Both models support the same pipe diameter range (Ø5-Ø10mm) and length range (150-500mm).

3. Controlled Heating Up to 280°C — Consistent Forming Temperature for Copper Heat Pipes
The standard model provides preheating and heating up to 280°C — raising the copper tube material to the optimal forming temperature before hydraulic pressure is applied. Forming at controlled temperature reduces the force required for consistent dimensional output, minimises spring-back, and prevents cracking of the copper tube wall or the internal sintered wick structure. Temperature control at the hot press station is a quality parameter that general-purpose hydraulic presses without integrated heating cannot provide — and it is one of the distinguishing capabilities of Cooling-Thermal's purpose-built thermal solution hot press machines.

4. Purpose-Built for Thermal Solution Heat Pipe Production — Not a General Hydraulic Press
Cooling-Thermal's hot press machine is engineered specifically for copper heat pipe forming in thermal solution manufacturing. The working area, die specifications, temperature system, and pressure parameters are all configured for the dimensional requirements of heat pipe flattening and profiling — not adapted from a general hydraulic press platform. This specialisation means the machine fits directly into the heat pipe production sequence with the correct working dimensions, cycle parameters, and die compatibility, without the process adaptation overhead that comes from using general-purpose pressing equipment on precision thermal solution components.

5. Hot Forging & Cold Forging Die Options — Matched to Your Pipe Specification
The standard model uses hot forging and pressing dies — appropriate for forming at elevated temperature where the copper material is softened for lower-force, high-accuracy forming. The heavy-duty model uses cold forging and pressing dies — suited for high-force, high-precision forming at ambient or lower temperatures, producing tighter dimensional tolerances and better surface finish on the pressed face. Die selection is matched to your specific pipe material, wall thickness, and dimensional tolerance requirements, and Cooling-Thermal's engineering team can advise on the correct die type and machine model for your thermal solution production application.

6. Factory-Direct from a Specialist Thermal Solution Automation Manufacturer
Cooling-Thermal is not a distributor or a general hydraulic press supplier. We are a specialist manufacturer of automation equipment for the thermal solution industry, operating factory-direct from our Kunshan, Jiangsu facility since 2017. Our hot press machines are part of complete heat pipe production lines we have delivered to Foxconn, Nidec, Furukawa Electric, and Cooler Master — ensuring that the machine's forming parameters are validated against the actual dimensional requirements of thermal solution customers, not against generic press specifications.

Applicable Pipe Specifications & Forming Applications — What the Heat Pipe Press Machine Can Form

The hot press machine is designed for the hydraulic forming of copper heat pipes used across the full range of thermal solution manufacturing applications. The following pipe specifications and forming applications are within machine capability:

• Standard round-to-flat forming — Ø5-Ø10mm copper heat pipes flattened to the contact surface profile for CPU cooler and server heat sink thermal solution assemblies
• Thin-wall heat pipe forming — Ø5-Ø8mm thin-wall copper heat pipes for laptop and compact electronics thermal solution applications, requiring controlled temperature and force to prevent wall cracking
• Large-diameter heat pipe pressing — Ø8-Ø10mm copper heat pipes for high-power server, industrial power electronics, and EV thermal solution applications requiring the 15-ton heavy-duty model
• Profile forming — non-flat pressed profiles for specific thermal solution contact geometries, using custom die configurations available through OEM/ODM customisation
• Multi-point pressing — heat pipes requiring multiple pressing positions along the pipe length, processed sequentially through the same die setup

If your heat pipe material specification, wall thickness, required flat geometry, or pressing tolerance falls outside standard configurations, contact our engineering team to discuss OEM/ODM customisation. As a specialist thermal solution automation manufacturer, Cooling-Thermal can develop custom die specifications and machine configurations for non-standard forming requirements.

Production Line Position — Where the Hot Press Machine Fits in Heat Pipe & Thermal Solution Manufacturing

For B2B procurement teams planning heat pipe production line integration, the hot press machine is positioned in the post-sealing, pre-bending phase of the manufacturing sequence — after the working fluid is sealed inside the tube and before the tube is bent to its final 2D or 3D shape. This sequence is critical: pressing must occur before bending because the flat section geometry created by the hot press determines the pipe's cross-sectional profile at the bend locations.

Why Pressing Must Come Before Bending
Attempting to flatten a heat pipe after it has been bent would require the press die to accommodate the bent geometry — which is not feasible with standard flat dies. Processing in the correct sequence (press flat first, then bend to shape) allows the hot press machine to work on a straight pipe section with a well-defined die contact area, achieving ±0.05mm pressing tolerance that would be unachievable if pressing was attempted on a pre-bent pipe. This production sequence logic is embedded in every complete heat pipe production line that Cooling-Thermal has designed and delivered.

Why Choose Cooling-Thermal?

Cooling-Thermal has delivered hot press machines as part of complete heat pipe production lines to Foxconn (25 lines), Nidec (20 lines), Furukawa Electric, and Cooler Master. Our machines operate at the ±0.05mm pressing tolerance required by these manufacturers' thermal solution products — not at general hydraulic press tolerances. This validated performance record is what differentiates Cooling-Thermal from general hydraulic press suppliers for B2B procurement of precision thermal solution forming equipment.
