Aluminum Case Small Capacitor Grooving and Sealing Machine

Product Overview

This high-precision grooving and sealing machine is engineered specifically for the synchronized circumferential grooving, spin-crimping, and edge-folding of aluminum-cased small capacitors and miniature cylindrical energy storage cells. By integrating an automatic clamping jacket with a dual-action rolling mechanism, the system executes groove formation and peripheral edge sealing in a single, fluid operational cycle. This synchronized approach eliminates intermediate part handling, shortens production cycle times, and delivers uniform, defect-free seal geometry across continuous manufacturing batches.

Designed to satisfy the stringent quality standards of the electronic components, supercapacitor, and consumer battery sectors, the equipment handles standard cylindrical formats while offering adaptable tooling setups for custom can dimensions. The rigid mechanical architecture, paired with high-precision linear guide feeds, prevents radial runout and ensures tight concentric alignment during high-speed rotation. This guarantees consistent mechanical interlocking between the aluminum shell and internal rubber sealing gasket without damaging internal electrode assemblies or separator films.

Built for continuous industrial duty, this tabletop production unit features an operational availability rate exceeding 98% and utilizes ultra-wear-resistant imported alloy tooling rated for more than 500,000 cycles. Its compact geometric footprint, low energy consumption, and ergonomic loading interface make it an exceptional solution for modern electronics manufacturing lines, rapid prototyping workshops, and advanced energy storage pilot facilities requiring high dimensional repeatability and dependable hermetic integrity.

Key Features

• Automatic Concentric Clamping Jacket: The integrated pneumo-mechanical clamping assembly firmly locks the aluminum casing in place, completely eliminating lateral wobble, vibration, and angular misalignment while ensuring coaxial centering for uniform 360-degree spin-crimping.
• Synchronized Grooving and Roll-Sealing: Engineered with a combined tool-actuation kinematic linkage, the unit forms the casing support groove and executes edge crimping simultaneously, substantially boosting throughput compared to sequential two-stage processing stations.
• Premium Imported Tooling Material: The grooving wheel and sealing rollers are precision-machined from high-hardness, wear-resistant imported alloy steel, providing exceptional dimensional retention and a verified tooling service life exceeding 500,000 continuous cycles.
• High-Precision Linear Guide Infeed: Tool engagement is driven along hardened linear guide rails that deliver micro-meter feed precision, preventing shell deformation, maintaining uniform groove depth tolerances, and ensuring repeatable crimp heights.
• Refined Geometric Enclosure and Ergonomics: The equipment features a clean, space-saving geometric design with an optimized working height and simplified operator controls, making loading, cycle initiation, and tooling changeovers intuitive and safe.
• Consistent Hermetic Sealing Performance: Mold-assisted rotary spin-crimping distributes mechanical deformation evenly across the aluminum perimeter, yielding leak-tight seals that reliably prevent electrolyte leakage and atmospheric moisture ingress.
• High Operational Availability: Designed for demanding production schedules, the rugged drive system and precision-machined structural framework achieve a certified 98% uptime rate with minimal preventive maintenance requirements.
