BFZ200 Secondary Vacuum Heat Sealing Machine

Secondary Vacuum Heat Sealing for Pouch Cell Battery Assembly

The BFZ200 Secondary Vacuum Heat Sealing Machine is designed for flexible lithium battery and pouch cell manufacturing workflows, particularly after electrolyte filling and standing vacuum steps. Its function is to remove trapped gases and seal the aluminium-laminated pouch under controlled vacuum, heat and pressure, helping improve package integrity and supporting more consistent cell finishing in battery research and pilot-scale production. This type of machine is commonly used for medium and small pouch cells during secondary packaging and final vacuum sealing stages.

Working Principle and Key Features

The machine operates by placing the pouch cell inside a corrosion-resistant aluminium alloy vacuum chamber. Once the chamber is evacuated, the sealing head applies controlled heat and pressure across the pouch edge to create a reliable thermal seal. Adjustable process parameters allow researchers and engineers to optimise sealing conditions for different laminate films, electrolyte systems and pouch geometries.

Key features include

• Aluminium alloy cavity with solid, corrosion-resistant structure
• Adjustable vacuum range up to -90 kPa
• Sealing head temperature adjustable from room temperature to 250°C
• Temperature control accuracy of ±1.5°C
• Heat sealing pressure adjustable from 0 to 7 kg/cm²
• Sealing time adjustable from 0 to 99 seconds
• Edge width of 5 mm, depending on customer requirements
• Maximum sealing edge size of 200 mm
• Pneumatic working speed of at least 180 times per hour
  
  

Compatibility and Research Applications

This machine is suitable for pouch cell R&D, lithium-ion battery prototyping, sodium-ion battery development and laboratory-scale battery fabrication lines where reproducible vacuum sealing is required. It can be integrated conceptually with related ScienceGears product categories such as battery cyclers, electrode preparation systems, gloveboxes and electrochemical testing platforms. Public listings for this model family show a 220 V / 50 Hz power supply requirement, compressed air input around 0.5 to 0.7 MPa, and working dimensions consistent with compact laboratory manufacturing equipment.

For researchers in Australia and New Zealand, ScienceGears provides local support, application guidance and access to complementary battery research instruments to help build a practical and scalable pouch cell assembly workflow.
