Manual Aluminum Plastic Film Forming Machine for Polymer and Pouch Lithium Batteries

Product Overview

This manual aluminum-plastic film forming machine is designed to stretch pre-cut aluminum-plastic laminate for polymer and pouch lithium battery packaging. The equipment uses a mold-closing process driven by a pneumatic-hydraulic intensifier cylinder: the operator places the film in the mold, presses two start buttons simultaneously, and releases them after forming. The mold then opens, completing the stretching cycle. This direct operating sequence supports controlled, repeatable film cavity preparation.

The unit is suited to polymer battery and soft-pack lithium battery development, pilot-scale assembly, and laboratory packaging workflows. It supports aluminum-plastic film sizes of 400300 or 500400mm, depending on configuration. The forming profile is determined by the installed mold, allowing the packaging geometry to match the required cell design rather than forcing a single fixed cavity arrangement.

Built around electroplated 45# steel structural components and substantial upper and lower platen construction, this system is configured for demanding forming work. Parallelism of the upper and lower platens is specified at <=0.15mm, helping maintain consistent mold closure across the working surface. A safety light curtain and two-button start arrangement provide combined protection during operation, while the air-pressure operating cycle is specified at less than four seconds.

Key Features

• Mold-Defined Forming Geometry: The aluminum-plastic film stretching shape is determined by the mold. This enables the equipment to be matched to the cavity geometry required for polymer and soft-pack lithium battery packaging.

• Adjustable Draw Depth: The larger-format configuration provides an adjustable aluminum-plastic film stretching depth of 1-30mm. This gives battery developers a defined adjustment range for pouch cavity depth requirements.

• Pneumatic-Hydraulic Forming Force: A pneumatic-hydraulic intensifier cylinder supplies the forming force, with a 5T configuration for the 400-format unit and a 15-ton configuration for the 500-format unit. Pressure magnitude can be specified according to customer requirements.

• Two-Hand Start Control: The operating sequence requires both start buttons to be pressed before the mold closes. Releasing the buttons opens the mold, creating a simple manual workflow for loading, forming, and unloading cut film.

• Integrated Operator Protection: A safety light curtain works together with the dual-button start system. This combined protection arrangement is included with the equipment for the mold-closing operation.

• Controlled Platen Alignment: Upper and lower platen parallelism is specified at <=0.15mm. This mechanical control supports uniform mold engagement when forming aluminum-plastic laminate.

• Robust Steel Construction: Main structural steel components use 45# steel with electroplating treatment. The platform construction uses 30-40mm upper and lower plates on the 400-format configuration and 58mm plates on the 500-format configuration.

• Fast Pneumatic Operating Cycle: The machine air-pressure operating cycle is specified at less than four seconds. This short cycle supports efficient repeated forming operations in laboratory and pilot production settings.

Applications

Technical Specifications

The two available equipment formats are retained as separate site-facing variants because their working film sizes, platen thicknesses, installed intensifier-cylinder capacities, power ratings, overall dimensions, and approximate weights differ. Selection should therefore be based on the aluminum-plastic film format, intended mold geometry, required stretching depth, and forming-force requirement of the battery packaging process.

For the 400-format configuration, the specified 5T pneumatic-hydraulic intensifier cylinder is paired with 400300 aluminum-plastic film handling. Its upper and lower platen thickness is specified as 30-40mm, and the equipment dimensions are 800760*1900mm. This configuration is appropriate where the required film format and mold arrangement align with its stated working envelope.

For the 500-format configuration, the specified 15-ton pneumatic-hydraulic intensifier cylinder is paired with 500400mm aluminum-plastic film. The configuration uses 58mm upper and lower platens, has overall dimensions of 870670*2000mm, and provides the stated 1-30mm adjustable stretching depth. This variant is the relevant choice when a larger film format and the specified deeper-draw adjustment capability are required.

Why Choose This Product

• Purpose-Built for Pouch Battery Forming: This equipment is specifically intended for aluminum-plastic film stamping and stretching in polymer and soft-pack lithium battery applications, rather than serving as a general-purpose pressing station.

• Mechanical Consistency Where It Matters: The <=0.15mm upper-to-lower platen parallelism specification, substantial platen thickness, and 45# steel structural components support stable mold closure during repeated forming work.

• Configuration Matched to Process Scale: Two distinct variants cover 400300 and 500400mm aluminum-plastic film formats, with different specified intensifier-cylinder capacities and platform constructions. This enables selection around actual forming requirements.

• Operationally Direct and Protected: The manual sequence is straightforward: load the cut film, actuate both start buttons, form, and release. The integrated safety light curtain and dual-button start arrangement support controlled operation around the closing mold.

• Customizable Forming Capability: The forming profile is mold-defined, while pressure magnitude can be specified according to customer requirements. This provides a practical basis for configuring the unit around a particular pouch design and process target.
