Rotary Hot Cold Press for Pouch Lithium Battery Cells

Product Overview

This rotary hot and cold press is designed for the heat-press forming and cold-press shaping stages of pouch lithium battery cell production. A motor-driven cam indexer coordinates a three-station rotary table for a continuous loading, hot pressing, cold pressing, and unloading sequence. The system combines adjustable thermal pressing, room-temperature cold pressing, controlled dwell time, and a maximum pressing output of approximately 5T.

The equipment is suited to pouch-cell manufacturing processes that require controlled cell thickness, high flatness, and parallelism between two planes in the thickness direction. It supports cell sizes within 10-350 mm length, 5-250 mm width, and 2-15 mm height, making it applicable to production of mid-range and high-grade pouch cells with demanding dimensional requirements.

Built for production-line operation, this unit provides a rated output of 300-600 pieces depending on product dimensions. The indexed rotary workflow simplifies material movement between process stages while the 350 × 350 mm upper and lower platens, adjustable pressure, and controlled temperature capability support repeatable pressing under defined operating conditions.

Key Features

• Three-Station Rotary Processing: A motor-driven cam indexer operates the rotary table through loading, hot pressing, cold pressing, and unloading stages. This organized sequence supports continuous material flow for pouch-cell forming and shaping operations.

• Integrated Hot and Cold Pressing: The equipment combines a hot-press station with a cold-press station operating at room temperature conditions. This enables the specified heat-press forming and cold-press shaping process to be completed within one rotary production workflow.

• Adjustable 5T Platen Pressure: The upper platen pressure is adjustable up to 5T, while the pressure cylinder provides a maximum output of approximately 5T. This gives operators a defined pressure capability for cell products within the stated dimensional range.

• Controlled Thermal Pressing: Hot-press temperature is adjustable from room temperature to 260°, with compensation setting capability and a control accuracy of ±3°. The adjustable 0-999 second holding time allows the pressing cycle to be set for the selected product process.

• Precision Indexing Performance: Indexer accuracy is specified at ±0.05-0.1 mm. This level of positioning capability supports the repeatable transfer of cells through the rotary stations during production.

• High Platen Parallelism: Upper and lower platen parallelism is specified at ±0.025 mm. Under a 1T setting pressure and the operating temperature, the imprint produced using three-part carbonless copy paper is required to be uniform.

• Broad Pouch-Cell Size Coverage: The unit accommodates products within 10-350 mm length, 5-250 mm width, and 2-15 mm height. It is also specified for cell thicknesses from 0-15 mm, covering the stated pouch-cell pressing envelope.

• Production-Oriented Capacity: Output is specified at 300-600 pieces, depending on product size. The equipment is intended for efficient, straightforward, safe, and reliable processing of pouch lithium battery cells.

• Defined Utility Requirements: Operation uses a 220V/50Hz power supply with 7.5KW installed power and compressed air of at least 0.8Mpa at 15L/Min. Clear utility requirements help production teams plan installation and line integration.

Applications

Technical Specifications

The stated capacity is dependent on product size. Production planning should therefore account for the dimensions of the pouch-cell product being processed within the specified dimensional envelope. The defined operating values for pressure, holding time, hot-press temperature, and cold-press temperature provide the available adjustment range for the relevant production process.

The cold-press temperature is specified as 5-20℃, while a cold-water machine is not included with the equipment. Where the user requires this arrangement, the chiller can be purchased separately. Installation also requires preparation for the stated electrical supply, compressed-air supply, equipment footprint, weight, and floor load capacity.

For quality verification of platen parallelism, the stated procedure uses three-part carbonless copy paper at a 1T pressure setting and the operating temperature. A uniform imprint is the stated result for this verification condition. This specification directly addresses the pressing surfaces used for products requiring high flatness and parallelism in the thickness direction.

Why Choose This Product
