ATOMFAIR® VPS820 VACUUM PRE-SEALING MACHINE

RESEARCH GRADE MATERIAL

Product Overview

The Atomfair‑VPS820 is a high-performance vacuum thermal sealing platform specifically engineered for the vacuum extraction and hot-press pre-sealing of pouch lithium-ion battery aluminum-plastic films following electrolyte injection and diffusion standing. Utilizing an advanced split architectural layout, this system integrates a high-rigidity sealing unit with a standalone control enclosure, enabling seamless deployment inside protective glove boxes or standard production configurations to deliver uncompromised joint hermeticity.

Key Features & Advantages

Premium Energy-Saving Copper Dies: Built with high-purity copper sealing heads that facilitate ideal heat transfer coefficients, delivering supreme thermal efficiency compared to traditional blocks.
Adjustable Interface Downforce: Mechanical pressure of upper and lower welding surfaces can be quickly adjusted via an integrated regulator to match custom stack specs.
Linear Bush Guide Alignment: Driven via an industrial cylinder linked with high-stiffness linear guide bushes, locking parallel margins within a tight ≤0.02 mm gap limit.
Integrated Cavity Inspection Window: Structural viewing window embedded directly into the face cover allows for real-time tracking of negative pressure sequences.
Rotary Guided Chamber Cover: Cylinder-driven vacuum door shifts smoothly along specialized rotary guide bushings to deliver flexible movement and reliable air tightness.
Universal Battery Size Adaptation: Demonstrates high modular versatility across extensive pouch cell form factors via quick internal nesting adjustments.
Glove Box Compatible Split Layout: Specialized separate layout isolates the heavy sealing unit from electrical controls, allowing clean remote operation inside an inert atmosphere.

APPLICATION SCOPE: Pouch cell degassing thermal sealing, primary aluminum-plastic film pre-sealing, inert glove box battery conditioning, and precision boundary leveling.

FACILITY REQUIREMENT: Benchtop or glovebox chamber workspace. System Net Weight: 50 kg. Separate control box can be isolated outside gas purifiers via custom feedthroughs.

IMPORTANT NOTICE: This equipment operates at extreme negative vacuum boundaries down to -95 KPa alongside heating blocks up to 300°C. Always confirm that input compressed air holds stable within 5–7 Kg/cm² parameters and verify that the sealing die faces are clean of volatile electrolyte residues before executing thermal loops.
