Pouch Cell Secondary Vacuum Final Sealing Machine

Product Overview

This system is designed for the puncturing and secondary vacuum final-sealing stage of pouch-cell production. It combines a sealed aluminum-alloy chamber, controlled vacuum processing, adjustable heated sealing heads, and pneumatic actuation in a compact workstation. The result is a repeatable process for closing pouch-cell edges after the required puncture operation, helping laboratories and pilot lines control the critical final package condition before subsequent cell handling or evaluation.

The equipment is intended for pouch batteries across different product sizes, with convenient adjustment to accommodate changing cell formats. It is relevant to battery research laboratories, pilot manufacturing environments, advanced-materials development teams, and organizations that need a dedicated station for secondary vacuum sealing. Adjustable sealing temperature, pressure, time, and vacuum conditions allow the process to be aligned with the applicable pouch material and production requirements.

Built for demanding repeated operation, the unit uses copper sealing heads for effective heat transfer and cylinder-driven guided motion for controlled alignment. The chamber is corrosion resistant and structurally robust, while the guided upper and lower mechanisms support parallel sealed edges and dependable chamber closure. These design choices focus on process consistency, efficient heating, and practical operation in space-conscious technical environments.

Key Features

• Automatic Puncturing Function: The integrated automatic puncturing function supports the required puncture step within the secondary vacuum final-sealing process. Integrating this operation into the workstation helps simplify handling between related pouch-cell finishing steps.

• Copper Heated Sealing Heads: The sealing heads are manufactured from copper to provide strong heat-transfer performance. Efficient thermal transfer supports productive heating behavior, helps reduce energy consumption compared with similar products, and improves working efficiency during repeated sealing cycles.

• Adjustable Sealing Pressure: A pressure-regulating valve allows the pressure of the upper and lower sealing heads to be adjusted. This gives operators a direct way to set the heat-sealing force for differing process parameters and pouch-cell requirements.

• Controlled Temperature Performance: Sealing-head temperature is adjustable from room temperature to 250°C with ±1.5°C temperature-control accuracy. This controlled operating range supports selection of the thermal condition appropriate to the pouch material and sealing process being used.

• Guided Head Movement: Cylinders drive the upper and lower sealing heads through two linear guide sleeves. The arrangement provides flexible vertical movement and accurate guidance, supporting the parallelism requirement of the sealed edge after the process is completed.

• Guided Chamber Cover Actuation: The chamber cover is cylinder driven and guided by linear guide sleeves. Smooth, accurately guided motion helps the cover meet the sealing requirement of the chamber during vacuum operation.

• Corrosion-Resistant Chamber Construction: The chamber is made from aluminum alloy, combining corrosion resistance with a firm structural form. This construction is suited to regular laboratory or pilot-line use where chamber integrity and operational stability are important.

• Configurable Sealing Cycle: Heat-sealing time is adjustable from 0 to 99 seconds, while thermal pressure is adjustable from 0 to 7Kg/cm2. These settings allow the sealing cycle to be configured around the required process window rather than fixed to one pouch specification.

• Multi-Size Pouch Compatibility: The unit can be used with batteries of different specifications, and adjustment is described as simple and convenient. Its 340mm sealing-width length and maximum 310mm sealing-edge size provide a defined working envelope for pouch-cell formats within the stated limits.

• Compact Pneumatic Workstation: The equipment combines vacuum, heat sealing, puncturing, and pneumatic movement in a small, lightweight form factor. It requires a buyer-supplied vacuum pump and a 0.5～0.7Mpa compressed-air source, making the required utility interfaces clear for installation planning.

Why Choose This Product

• Engineered for Repeatable Pouch Sealing: Copper sealing heads, adjustable pressure, timed heat sealing, and ±1.5°C temperature-control accuracy provide the key controls needed to establish a consistent secondary final-sealing process.

• Built Around Mechanical Alignment: Cylinder-driven movement with linear-guide support is designed for flexible, accurate travel. The guided sealing-head arrangement supports the parallelism requirement for sealed pouch edges, while the guided chamber cover supports chamber sealing performance.

• Designed for Demanding Technical Use: The corrosion-resistant aluminum-alloy chamber provides a firm structural foundation for repeated vacuum-process operation. Clearly defined vacuum, compressed-air, electrical, and heating requirements help facilities assess integration needs before procurement.

• Adaptable Within a Defined Process Window: Adjustable temperature, pressure, sealing time, and support for different battery specifications enable the workstation to be configured for varying pouch-cell process parameters. The stated sealing dimensions and thickness range give buyers concrete limits for matching the unit to their cell format.

• Practical Investment for Laboratory and Pilot Work: Automatic puncturing, compact dimensions, and a focused set of pneumatic and thermal controls bring related pouch-finishing tasks together in one equipment platform. This supports efficient operation while preserving the adjustment capability needed in development and small-batch environments.
