Aluminum Steel Shell Lithium Battery Vacuum Steel Ball Sealing Machine

Product Overview

This vacuum steel ball sealing machine is designed for lithium batteries with steel or aluminum shells that require evacuation followed by steel-ball closure. Its left-right dual-chamber arrangement enables parallel handling: one battery can undergo vacuum sealing while another position is available for loading or unloading. This workflow supports efficient manual operation while maintaining a controlled, repeatable sequence for cell closure.

The equipment is suited to lithium-battery laboratory production, pilot-scale cell fabrication, and process development involving shell-type cells. It accepts battery dimensions within the stated thickness, width, and height ranges, with the acceptance product specification referenced to 60 Ah. Initial fixtures and steel-ball compatibility are configured against the battery and ball samples supplied for the order, helping align the working interface with the intended cell format.

Built for stable operation, this unit combines fixture positioning, adjustable vacuum settings, controlled ball feeding, and a separate control cabinet positioned outside the glove box. Major machine components receive chrome treatment for rust and corrosion resistance. The result is a practical closure station for teams that need dependable handling, accurate ball placement, and clearly controlled vacuum-sealing steps under demanding cell-manufacturing conditions.

Key Features

• Dual-Chamber Parallel Workflow: The left and right chambers support alternating cell handling. While one side performs vacuum and steel-ball sealing operations, the other side can be used for manual loading or unloading, reducing avoidable idle time between cycles.

• Vacuum Before Ball Sealing: The operating sequence evacuates the cell before the steel ball is delivered and pressed into place. Vacuum time is adjustable from 1 to 999 seconds, allowing operators to set the process duration from the front panel according to the applicable cell requirement.

• Controlled Vacuum Setting: Vacuum pressure values can be set simply from the panel. The stated vacuum control range is -85 to -90 Kpa, while the operating description identifies vacuum reaching -85 to -95 Kpa during the sequence.

• Accurate Fixture Location: Both upper and lower chambers include positioning provisions to support steel-ball sealing accuracy. The stated ball-sealing deviation accuracy is ±0.1 mm, helping users maintain consistent placement from cycle to cycle.

• Single-Ball Feeding Arrangement: A dedicated steel-ball delivery cylinder advances one steel ball at a time from the storage trough before the pressing cylinder completes the sealing action. The storage trough provides useful holding capacity for convenient operation.

• Configurable Cell and Ball Interface: Initial fixture dimensions and steel-ball suitability are based on the ordered battery model and supplied ball sample. This order-based arrangement supports application-specific setup without requiring users to rely on a one-size fixture interface.

• Corrosion-Conscious Construction: Main structural components are chrome treated to resist rust and corrosion. The independent electrical control cabinet is installed outside the glove box to avoid corrosion exposure in that working environment.

• Stable Pneumatic Sequence: Feed, sealing, ball-delivery, and ball-pressing cylinders execute a defined sequence, then return to their initial positions before compressed air releases the vacuum. The equipment is designed for safe, stable running, reliable control, and straightforward operation.

• Production-Oriented Performance: Output is specified at 40-100 ea/H, depending on worker operating proficiency, with a stated finished-product rate of at least 98%. Noise is specified at no more than 60 db, supporting its use in organized laboratory and pilot-production work areas.

Why Choose This Product

• Purpose-Built Closure Sequence: This system integrates fixture loading, evacuation, single-ball delivery, ball pressing, mechanism reset, and vacuum release in the stated process order. It gives cell-development teams a focused solution for vacuum steel-ball sealing rather than a collection of disconnected manual steps.

• Precision Where the Closure Matters: Upper and lower chamber positioning devices work with the stated ±0.1 mm ball-sealing deviation accuracy. This attention to location control is valuable when evaluating consistency across repeated shell-cell closure operations.

• Designed for Repeated Use: Chrome treatment on major components addresses rust and corrosion resistance, while the separate external control cabinet helps avoid corrosion exposure inside a glove-box environment. These details support dependable operation in laboratory cell-processing settings.

• Adapted to the Ordered Cell Format: Initial fixture sizing and ball compatibility are based on the battery model and steel-ball sample supplied for the order. This makes the equipment a more considered investment for a defined shell-cell process.

• Operationally Transparent Performance: Clearly stated requirements for power, compressed air, vacuum source, compatible dimensions, output, noise, and vacuum adjustment allow engineering and procurement teams to assess installation readiness before purchase.
