Vacuum Standing Pre Sealing and Side Sealing Two in One Machine for Pouch and Cylindrical Batteries

Product Overview

This vacuum standing and pre sealing side sealing system combines electrolyte standing treatment with vacuum heat sealing in one compact unit. It supports electrolyte absorption and improved electrode integration during pouch and cylindrical battery filling, then removes air and performs thermal pre sealing on pouch battery aluminum plastic packaging. Precise control of vacuum extraction, dwell time, sealing temperature, and pneumatic pressure helps create a repeatable battery preparation process.

The equipment is suited to battery R&D laboratories, pilot production lines, glovebox environments, and academic materials research. Its split host and control box design allows installation inside a glovebox or integration into a production line. A corrosion resistant aluminum alloy chamber, transparent viewing window, and lightweight construction support practical operation where workspace, visibility, and process control are important.

Designed for demanding development workflows, this unit provides adjustable process parameters, guided pneumatic movement, and multi-stage cycling to encourage more complete electrolyte fusion. Brass sealing heads transfer heat efficiently, while linear guide sleeves help maintain accurate movement, sealing alignment, and consistent edge quality over repeated operation.

Key Features

• Combined Vacuum Standing and Pre Sealing: Performs electrolyte standing under vacuum and pouch battery vacuum heat pre sealing within one integrated system, reducing handling between process stages.

• Efficient Brass Sealing Heads: Brass construction provides effective heat transfer, helping reduce energy consumption during heating while supporting efficient and consistent sealing performance.

• Adjustable Sealing Pressure: Upper and lower head pressure can be regulated through an adjustment valve from 0 to 8 Kg/cm2, allowing operators to match the process to different battery formats and sealing requirements.

• Controlled Temperature and Dwell Time: Sealing temperature is adjustable from room temperature to 250°C with ±2°C control accuracy. Heat sealing time can be set from 0 to 99 seconds for repeatable process development.

• Accurate Guided Pneumatic Motion: The upper and lower sealing heads are cylinder driven and guided by two linear guide sleeves. Smooth vertical movement and accurate guidance help maintain sealing parallelism and edge uniformity.

• Transparent Process Visibility: A viewing window allows operators to observe changes inside the chamber during vacuum extraction, electrolyte standing, and sealing operations.

• Multi Stage Cycling: Multiple cycle operations can be configured to promote more complete electrolyte fusion, supporting repeatable preparation of cells that require controlled standing treatment.

• Flexible Product Adjustment: The sealing structure accommodates batteries in different specifications. Adjustment is designed to be straightforward and convenient when changing product formats.

• PLC and Touchscreen Operation: PLC plus touchscreen control provides an accessible interface for setting and monitoring vacuum standing, pressure, temperature, and sealing time parameters.

• Compact Split Design: Separating the main machine from the electrical control box allows flexible placement inside a glovebox or on a production line while keeping the footprint practical for laboratory environments.

Applications

Technical Specifications

The adjustable vacuum standing time extends from 0 to 9999 seconds, giving development teams room to establish process recipes for different electrolyte quantities, cell formats, and experimental conditions. Standing pressure is also adjustable, allowing the operator to coordinate vacuum treatment with the desired electrolyte integration behavior. The vacuum level can exceed -95 KPa when connected to a buyer supplied vacuum pump.

The pneumatic sealing assembly is designed for controlled and repeatable motion. Independent pressure adjustment allows the upper and lower heads to be matched to different packaging materials and process requirements. The two linear guide sleeves constrain movement during cylinder actuation, helping maintain parallel contact between the sealing heads. This arrangement supports a uniform seal while reducing the risk of uneven loading across the 200 mm sealing knife length.

For thermal process control, the brass heads operate from room temperature to 250°C, with temperature adjustable across the range and control accuracy of ±2°C. Operators can set heat sealing time between 0 and 99 seconds. The standard sealing edge width is 5 mm, while other widths can be customized for supported applications. Under the stated 0.6 MPa head air pressure and 200°C test condition, the seal produced with three layer carbonless copy paper is uniform, providing a practical indication of head parallelism.

The aluminum alloy chamber combines corrosion resistance with a firm structure suitable for repeated vacuum and sealing work. The viewing window provides direct visibility into chamber changes, which is useful when observing gas removal, electrolyte movement, and the progress of the standing cycle. PLC and touchscreen control simplify parameter entry and support a clear operating sequence for laboratory technicians and production personnel.

Installation requirements should be reviewed before purchase. The electrical supply is 220 V / 50 Hz, and the compressed air source should provide 0.4 to 0.6 Mpa. Air consumption is approximately 0.2 L of compressed gas for each seal, with a pneumatic operating speed of at least 180 cycles per hour. When the equipment operates in a glovebox, the cylinder must use the same working gas available inside that glovebox. A vacuum pump is required for operation and is supplied by the buyer.
