Vapor Chamber Vacuum Filling & Welding Machine
Designed for high-performance thermal management products such as AI server cold plates, EV battery vapor chambers, and 5G base-station heat spreaders, the machine supports DI water, methanol, ethanol, acetone, and other working fluids through chemically compatible flow paths.
Product Description
A VC vacuum degassing and sealing machine is an integrated production equipment that combines multi-stage vacuum degassing, precision working-fluid filling, and hermetic sealing into a single automated cycle for vapor chamber (VC) manufacturing. Unlike conventional single-process machines that handle each step separately, our all-in-one system performs loading, port positioning, local vacuum sealing, rough and high-vacuum degassing, closed-loop filling, pre-sealing, and final welding within one machine cycle — eliminating product transfer losses and improving batch-to-batch consistency.

Why Choose Our All-in-One VC Sealing Equipment
Four core values define what European and global thermal manufacturers consistently demand: process stability, modular adaptability, traceable quality control, and long-term reliability. Our machine is engineered around them:
• Modular quick-change fixtures — One machine handles multiple VC sizes via recipe-based changeover in under 15 minutes.
• Local vacuum sealing chamber — Only the filling port area is evacuated, reducing pump load and cycle time by 40-60% vs. full-chamber designs.
• Closed-loop precision filling — Servo metering pump + mass flowmeter + weighing feedback achieve ≤±1% filling accuracy.
• Two-stage sealing (pre-seal + final weld) — Eliminates air re-ingress and working-fluid evaporation between filling and welding.
• Full data traceability — Vacuum level, filling weight, pressure decay, welding parameters and NG reasons are logged and exportable to MES/SCADA.
• International components — SMC, Festo, Pfeiffer, Edwards, Siemens, Schneider, Keyence — for global service-network compatibility.
• CE-oriented safety design — Safety interlocks, light curtains, e-stop circuits, and clearly defined maintenance zones.
Key Innovative Modules & Technical Highlights
1. Modular Quick-Change Fixture
The fixture adopts a modular quick-change structure including a positioning base, port guide, side clamping unit, anti-deformation support, flexible sealing ring, and filling interface. Changeover between product models takes under 15 minutes via recipe selection — no tools required for standard SKU switches.
2. Local Vacuum Sealing Chamber
Instead of evacuating a large chamber, the system creates a local sealed space only around the product filling port. This reduces evacuation volume, shortens cycle time, minimizes working-fluid loss, and simplifies seal maintenance. Pump load is reduced by 40-60% compared with full-chamber designs.
3. Closed-Loop Precision Filling
Controlled by servo metering pump, mass flowmeter, or weighing feedback — or any combination of the three. The system auto-calls filling volume, speed, pressure, and temperature-compensation parameters per product recipe, enabling highly consistent batch production with ≤±1% accuracy.
4. Two-Stage Sealing: Pre-Seal + Final Weld
After filling, the product is first pre-sealed to prevent air re-ingress and working-fluid evaporation. Final sealing is then performed. Available final-sealing methods include mechanical crimping, laser welding, resistance welding, TIG welding, and other material-specific processes.
Applications
Our VC vacuum degassing and sealing machine serves R&D labs, pilot lines, and mass-production factories across the following sectors:
• AI server & data-center cooling — vapor chambers for NVIDIA GB200 / GB300 GPU modules
• Power electronics — IGBT / SiC module cold plates
• 5G communication — base-station and small-cell heat spreaders
• Consumer electronics — smartphone, laptop, and gaming-console vapor chambers
• Electric vehicles — EV battery-pack thermal management and motor-controller cooling
• Industrial automation — high-power LED, laser modules, medical imaging cooling
FAQ
What is the cycle time per vapor chamber?
Typical cycle time ranges from 45 to 120 seconds per piece depending on VC size, vacuum requirement, and sealing method. Final cycle time is locked during prototype validation.
Can the same machine handle both heat pipes and vapor chambers?
Yes. Through modular quick-change fixtures and recipe-based parameter switching, a single machine can process heat pipes, flat heat pipes, vapor chambers, and micro-channel cold plates. Changeover takes under 15 minutes.
Which working fluids are supported?
DI water, methanol, ethanol, acetone, and refrigerants such as R134a and R1234yf. Fluid paths are selected based on chemical compatibility; flammable fluids require explosion-proof zoning and forced ventilation.
What filling accuracy can you guarantee?
Target accuracy is ±1% or better, depending on filling method (servo pump / flowmeter / weighing feedback) and fluid type. Final accuracy is locked during FAT (Factory Acceptance Test).
What is the typical lead time?
Standard configurations: 30-45 days from order confirmation. Heavily customized lines: 60 days. We welcome on-site or video FAT before shipment.
