Semi Automatic Aluminum Plastic Film Forming Machine for Polymer Lithium Batteries

Product Overview

This semi-automatic forming system is designed to punch and form aluminum-plastic laminate film into pouch shells for polymer lithium batteries. It combines a 3T power source with a four-guide-post structure to produce stable, accurately guided forming motion. The equipment supports deep, controlled pocket formation while protecting the integrity of the pocket and PP layer. Its compact footprint, straightforward operation, and rapid mold adjustment make it suitable for controlled pouch-cell shell preparation.

The unit is intended for soft-pack lithium battery manufacturing processes that require single-pocket four-side-seal shells, as well as single- or double-pocket folded shells. It is appropriate for battery R&D, pilot production, process verification, and production operations where pouch dimensions, pocket depth, and formed-edge quality need close control. Operators place a cut film sheet in the mold, locate it correctly, start the cycle, and remove the formed film after automatic punch-shell forming is complete.

Reliability is built into the mechanical and safety design. Four guide posts support smooth, high-precision upper and lower movement, while precision mold design is specified to prevent fishtail wrinkles and collapsed corners around formed corners and edges. A light curtain and protective enclosure support safer operation. High-strength chrome steel, alloy aluminum, imported mold materials, environmentally compliant electroplating, and baked paint finishing support durable use under repeated forming conditions.

Key Features

• Four-Guide-Post Precision Structure: Four guide posts provide smooth upper and lower sliding movement with high positioning precision. This rigid guidance approach supports stable mold alignment through repeated punch-shell forming cycles.

• Deep and Stable Pocket Forming: The equipment is designed to stretch aluminum-plastic film deeper and more stably than comparable equipment processing film of the same quality. Forming depth is specified at up to 6 mm while maintaining a pocket without damage and a PP layer without wrinkles.

• Precision Mold Geometry: The mold is engineered to form clean corners and surrounding edges without fishtail wrinkles or collapsed corners. Mold and mold-core roughness of 0.4, together with 0.02 mm flatness requirements for the upper/lower mold planes and mold core, support controlled contact and formed-part quality.

• Fast Tooling Adjustment: Mold replacement and draw-depth adjustment are designed to be simple and quick. This helps production teams prepare the system for shell dimensions determined by the required pocket-forming size.

• Defined Forming Accuracy: The system specifies forming-length and forming-width tolerances of +/-0.2, plus a forming-thickness tolerance of +/-0.1. These values provide procurement and process teams with clear dimensional targets for shell-forming operations.

• Semi-Automatic Operating Sequence: After the cut aluminum-plastic film is placed and located in the mold, an operator presses the start button. The power source automatically drives the mold to form the shell, after which the formed film is removed to complete the cycle.

• Integrated Operator Protection: A light curtain and protective enclosure are incorporated for safer equipment use. The safeguards complement the controlled start-button process and enclosed forming area.

• Production-Oriented Throughput: Rated capacity is 200-400 EA/H. This output range supports repeatable pouch-shell forming where a semi-automatic workflow is preferred for material handling and process control.

• Compact Industrial Construction: The equipment measures approximately 460 x 320 x 925 mm and weighs approximately 150 kg. Its compact form is paired with a geometrically designed sheet-metal enclosure intended to maintain a clean, refined equipment appearance.

• Durable Finished Components: The construction uses imported mold material, high-strength chrome steel, and alloy aluminum. Environmentally compliant electroplating and baked paint treatment provide a finished surface suitable for the equipment's mechanical assembly.

Why Choose This Product

• Controlled forming quality: The four-guide-post structure, defined mold flatness values, and precision mold design focus the system on smooth movement, stable forming, and consistent shell geometry.

• Protection of critical film layers: The stated forming requirement calls for a pocket without damage and a PP layer without wrinkles at punch-shell depths up to 6 mm. This directly addresses a key quality consideration in aluminum-plastic film shell forming.

• Practical setup flexibility: Mold replacement and draw-depth adjustment are designed for simple, rapid operation, while the mold section is determined according to the required punch-shell size. This supports tooling selection around the intended pouch format.

• Durable mechanical build: Imported mold materials, high-strength chrome steel, alloy aluminum, electroplating, and baked paint treatment give the equipment a robust construction basis for repeated manufacturing use.

• Operational confidence: The semi-automatic sequence is direct to operate, and the light curtain with protective enclosure adds safety protection around the forming process. Rated capacity of 200-400 EA/H provides a clear production reference for procurement planning.
