Vacuum Electrolyte Filling Resting Hot Press Pre Sealing Integrated Machine

Product Overview

This integrated system combines vacuum electrolyte filling, standing, and hot-press pre-sealing in one controlled work sequence for battery capacitors and related cell formats. The process evacuates the cell first, fills electrolyte, allows a defined standing period, and then performs hot-press pre-sealing. This sequence is designed to support high filling accuracy, consistent electrolyte absorption, and dependable process repeatability while reducing transfers between separate workstations.

The equipment is intended for battery and capacitor manufacturing workflows where pouch dimensions, fill volume, temperature, pressure, and dwell time must be managed with care. It can be operated in a glove box or dry room, making it suitable for moisture-sensitive assembly environments. Adjustable vacuum, timing, dispensing, sealing temperature, and sealing pressure give process teams practical control over each stage.

Built with corrosion-resistant 304 and 316 stainless-steel components, a welded aluminum vacuum chamber, chemically resistant hose connections, and guided pneumatic motion, this unit is engineered for stable operation. PLC and touchscreen control provide a flexible automated program interface, while the viewing window allows operators to observe chamber changes during operation.

Key Features

• Integrated Three-Stage Processing: This system incorporates electrolyte filling, standing, and pre-sealing in a single machine. Keeping these operations together supports a defined vacuum-first, fill, rest, and hot-seal sequence without unnecessary handling between stages.

• Vacuum-First Filling Sequence: The chamber is evacuated before electrolyte is dispensed. This controlled order supports efficient filling, accurate delivery, and more consistent electrolyte absorption across processed cells.

• High Dosing Repeatability: Electrolyte filling accuracy is specified at +/-1%, with an adjustable discharge speed of up to 6 ml/s. The equipment supports process development and repeated manufacturing work where dosing consistency is a central quality requirement.

• Adjustable Standing Conditions: Low and high vacuum settings and standing time are adjustable. Individual time settings can be configured up to 9999 min, allowing the workflow to be matched to the required process schedule.

• Controlled Hot Press Pre-Sealing: Sealing-head temperature is adjustable from room temperature to 250 degrees C, while heat-sealing pressure is adjustable from 0 to 5 Kg/cm2 and time from 0 to 99 seconds. These settings enable the unit to accommodate differing pre-seal process conditions.

• Thermally Efficient Copper Seal Heads: The seal heads are made from copper for effective heat transfer. The heating design uses a 300 W heating tube and has approximate heating power consumption of 0.6 KW, supporting efficient temperature delivery during the sealing cycle.

• Accurate Guided Pneumatic Motion: Upper and lower seal heads are cylinder-driven and guided by two linear guide sleeves. This arrangement supports flexible vertical movement, accurate guidance, and the parallelism requirement after edge sealing.

• Sealing Pressure Adjustment: A pressure-regulating valve independently enables adjustment of the upper and lower seal-head pressure. Operators can set the pressing condition to meet different process parameters rather than relying on a fixed force setting.

• Corrosion-Resistant Fluid Path and Chamber Construction: Inlet and outlet connections use chemically resistant flexible hose with Phi 6 tubing. Key areas use 304 and 316 stainless steel, and the vacuum chamber is aluminum welded for a corrosion-resistant, structurally stable enclosure.

• Automated, Observable Operation: PLC and touchscreen operation provide flexible parameter management and a high degree of programmed automation. A transparent viewing window permits observation of changes inside the chamber during a working cycle.

Why Choose This Product

• Purpose-Built Process Integration: The equipment brings vacuum filling, standing, and hot-press pre-sealing into a single automated platform. This supports a consistent sequence for teams seeking to manage key pouch-cell preparation stages within one unit.

• Precision Where It Matters: Specified +/-1% electrolyte filling accuracy, +/-2 degrees C temperature-control accuracy, adjustable dispensing speed, and controlled sealing parameters address the variables that directly influence repeatable assembly work.

• Robust Materials for Electrolyte Handling: Corrosion-resistant 304 and 316 stainless-steel parts, chemically resistant flexible tubing, copper seal heads, and a welded aluminum vacuum chamber provide a durable construction approach for this application.

• Engineered Sealing Consistency: Pneumatic actuation with linear and rotary guidance supports accurate movement of the seal heads and chamber cover. Adjustable upper and lower pressure helps align the operation with different process requirements.

• Adaptable to Process Requirements: Broad adjustable ranges for standing time, sealing temperature, pressure, time, fill capacity, and fill quantity give laboratories and production teams practical latitude. The seal-edge width can also be provided according to customer requirements.
