Pneumatic Aluminum Plastic Film Forming Machine for Pouch Lithium Battery Shell Forming

Product Overview

This pneumatic aluminum plastic film forming machine is engineered for shell-pocket forming of aluminum-plastic laminate used in pouch lithium batteries. Pneumatic actuation delivers adjustable forming pressure and speed without an electrical power requirement, providing a compact, practical solution for controlled laboratory processing. Its precision mold system is designed to create formed pockets with clean corners, stable geometry, and a smooth surrounding perimeter.

The equipment is intended for sheet-form aluminum-plastic film in battery R&D, pilot-scale prototyping, and sample preparation. It supports the production of pouch-cell shells before downstream cell assembly steps, making it relevant to battery laboratories, material-development teams, universities, and research institutes working with laminated pouch formats.

Built around four guide columns, a high-strength frame, and precision tooling, this unit emphasizes repeatable motion under routine laboratory use. Adjustable forming conditions, rapid depth adjustment, and convenient mold replacement help operators adapt the process efficiently while maintaining a controlled, reliable forming workflow.

Key Features

• Pneumatic Forming Drive: A cylinder-driven architecture provides the forming force without electrical power. Both forming pressure and forming speed are adjustable, enabling the operator to set the process according to the aluminum-plastic film and pocket-forming task.

• Adjustable Pressure up to 1 T: The system reaches a maximum forming pressure of 1 T at 0.5 MPa compressed air. This adjustable pressure capability supports controlled stretching rather than a fixed, one-condition forming process.

• Four-Column Precision Guidance: Four guide columns support smooth upper-and-lower sliding movement. This structural arrangement is designed to maintain accurate alignment through the forming stroke and support consistent pocket geometry.

• Deep and Stable Stretching: The equipment is designed to stretch equivalent-quality aluminum-plastic film more deeply and more stably than comparable products. It supports a maximum pocket depth of 6 mm within the stated applicable pocket dimensions.

• Precision Mold Geometry: The mold design is intended to minimize fish-tail wrinkles and collapsed corners around the formed pocket and perimeter. This is especially important when producing pouch shells that require clean, intact formed areas for subsequent battery-processing operations.

• Fast Mold and Depth Changes: Mold replacement and stretch-depth adjustment are simple and quick. This helps research teams change between supported development tasks without making the forming station unnecessarily complex to operate.

• Sheet Film Processing: The unit forms individual sheets of aluminum-plastic film rather than requiring a continuous-roll process. This makes it well suited to R&D, trial builds, and sample-making work where material quantities and pouch formats may change frequently.

• Dual-Button Safety Start: A two-button start arrangement supports safe operation by requiring a deliberate start action. The interface is designed to keep routine forming straightforward while prioritizing operator safety and dependable use.

• Durable Tooling and Surface Treatment: The tooling uses imported Japanese mold material together with high-strength chromium steel. Environmental electroplating and baked-paint surface treatments contribute to a durable, finished equipment exterior.

• Compact Laboratory Footprint: With an approximate footprint of 420 mm by 280 mm and a height of 510 mm, the equipment fits efficiently into laboratory cell-fabrication layouts. Its compact physical format supports placement near related pouch-cell preparation processes.

Applications

Technical Specifications

The dimensional limits above define the supported forming envelope: pocket length up to 65 mm, pocket width up to 50 mm, and depth up to 6 mm. Aluminum-plastic film should remain within 160 mm in length and 105 mm in width. These values enable procurement and process teams to verify fit with their intended pouch-shell format before selecting tooling and establishing forming conditions.

The maximum 1 T forming pressure is referenced to 0.5 MPa compressed air. Because both pressure and speed are adjustable, process personnel can establish an appropriate forming setting for the selected film and required pocket geometry. The equipment is specified for a forming accuracy of ±0.05 mm, supported by the four-column guidance structure and precision mold design.

Why Choose This Product

• Purpose-Built for Pouch-Cell Shell Forming: This system is specifically configured for pneumatic forming of aluminum-plastic film pockets used in soft-pack lithium-battery work, rather than being a general-purpose pressing platform.

• Precision Where It Matters: Four-column guidance, precision tooling, and ±0.05 mm forming accuracy provide a strong foundation for repeatable pocket dimensions and aligned forming movement.

• Premium Tooling Focus: Imported Japanese mold material, high-strength chromium steel, and protective surface treatments reflect a build approach centered on durability and stable laboratory operation.

• Flexible for Development Work: Adjustable forming pressure, adjustable speed, rapid mold replacement, and simple stretch-depth adjustment help laboratories respond efficiently to changing R&D and sample-preparation requirements.

• Designed for Clean Forming Results: The mold geometry is designed to avoid fish-tail wrinkles and collapsed corners, while the stated result requirement protects pocket integrity and PP-layer appearance.
