Three in One Resting Pre Sealing and Secondary Sealing Machine

Product Overview

This system combines secondary sealing, resting, and pre-sealing functions for pouch and cylindrical battery processing. It is designed to support electrolyte absorption under vacuum, helping electrolyte contact the electrode sheets more completely during cell filling. After electrolyte injection and resting, the equipment can evacuate and thermally pre-seal aluminum-plastic pouch cell housings through controlled vacuum extraction and pneumatic hot-sealing actions.

The unit is intended for battery R&D, pilot-scale cell development, and process laboratories working with pouch batteries and cylindrical batteries. Its integrated workflow supports teams that need to move from electrolyte filling and static soaking to vacuum treatment and heat-sealed packaging without separating these related process steps across different stations.

A corrosion-resistant aluminum-alloy chamber, brass sealing head, adjustable thermal settings, and pneumatic operating controls provide a robust foundation for repeatable battery packaging work. Configurable resting time, heat-sealing pressure, sealing duration, and sealing-head temperature allow the equipment to be set according to the process requirements of the cell under production.

Key Features

• Integrated Three-Function Workflow: This system incorporates secondary sealing, resting, and pre-sealing in one unit. It supports the sequence of electrolyte absorption under vacuum, post-injection resting, evacuation, and thermal pre-sealing for battery cell packaging processes.

• Vacuum-Assisted Electrolyte Absorption: The equipment is designed to assist electrolyte absorption so that electrolyte and electrode sheets can combine more completely in a vacuum environment. Vacuum can reach more than -95KPa when the buyer provides the vacuum pump.

• Adjustable Resting Control: Resting time is adjustable from 0 to 9999S, with adjustable pressure. This gives operators a configurable dwell stage after electrolyte injection before the subsequent vacuum and pre-sealing operation.

• Controlled Pneumatic Hot Sealing: Heat-sealing pressure is adjustable from 0 to 8Kg/cm2, while sealing time is adjustable from 0 to 99 seconds. These controls allow the sealing cycle to be matched to the required package-processing conditions.

• Adjustable Thermal Sealing Head: The brass sealing head operates from room temperature to 250℃ with adjustable setpoint control. Temperature-control accuracy is ±2℃, supporting stable thermal conditions during the sealing operation.

• Durable Chamber Construction: The chamber is made from aluminum alloy for corrosion resistance and structural strength. This construction is suited to repeated laboratory and production-support use where the chamber is exposed to battery-processing operations.

• Consistent Sealing-Head Alignment: Sealing-head parallelism is verified using triple carbonless copy paper. At 0.6MPa sealing-head air pressure and 200℃, the resulting seal impression is uniform, providing a practical reference for sealing-face consistency.

• Production-Oriented Cycle Capacity: The pneumatic operating speed is at least 180 cycles per hour, with compressed-air consumption of approximately 0.2L per seal. This supports repeatable operation where multiple cells require controlled processing during a working shift.

• Configurable Sealing Format: The standard sealing-edge width is 5mm and the sealing-knife length is 400mm. Other sealing-edge widths can be customized to accommodate process-specific packaging requirements.

Applications

Technical Specifications

The specification set is organized around the stages that matter during battery packaging: holding after injection, establishing vacuum conditions, applying controlled heat and pressure, and maintaining the required utility supply. Buyers can use the adjustable ranges to compare the equipment with their process window and facility infrastructure.

For installation planning, the machine section and electrical box are listed separately. The compressed-air requirement is 0.4-0.6Mpa, while the electrical requirement is 220V/50Hz. Where the unit is installed inside a glove box, the pneumatic cylinder must be supplied by the same working gas used within that glove-box environment.

The thermal and mechanical sealing parameters are independently adjustable within the stated ranges. The operator can set the sealing-head temperature from room temperature to 250℃, heat-sealing pressure from 0 to 8Kg/cm2, and heat-sealing time from 0 to 99 seconds. Together with the 0-9999S resting setting, these controls define the principal configurable parts of the operating sequence.

The standard 5mm sealing-edge width and 400mm sealing-knife length establish the supplied sealing format. For applications requiring a different sealing-edge width, customization is available. The documented parallelism condition provides an objective check of seal-head contact: under the specified 0.6MPa and 200℃ test conditions, triple carbonless copy paper receives a uniform impression.

Why Choose This Product

• Purpose-Built Process Integration: This equipment brings resting, pre-sealing, and secondary sealing into one battery-processing platform. The integrated arrangement is commercially valuable for teams that need these related functions available within a defined workflow.

• Defined Control Ranges: Adjustable resting time, pressure, sealing temperature, heat-sealing pressure, and sealing time give process engineers specific operating variables rather than a fixed single-condition setup. The stated ranges make the unit easier to assess against established development or production procedures.

• Robust Core Construction: The corrosion-resistant aluminum-alloy chamber and brass sealing head are selected construction features for a durable process platform. The equipment is configured around pneumatic actuation and a 500w heating tube for the required vacuum and thermal packaging stages.

• Practical Verification and Utility Detail: Uniform seal impressions under the stated parallelism test condition, a defined compressed-air range, listed electrical supply, and separate machine and electrical-box dimensions give procurement and facility teams concrete information for evaluation and installation planning.

• Adaptable Sealing Configuration: A 5mm standard sealing edge is supplied, while other sealing-edge widths can be customized. This allows the sealing format to be considered alongside the cell package and process requirements rather than treated as a fixed commodity constraint.
