Capacitor Tab Punching Machine

Product Overview

This capacitor tab punching machine is designed for accurately punching round holes in capacitor cell tabs before riveting the tabs to washer and end-cap assemblies. Its guided cutting structure, positioning device, and compact operating format support repeatable tab preparation while simplifying handling for laboratory and pilot-scale production workflows.

The unit is particularly suitable for capacitor cell fabrication, tab preparation, glovebox-based processing, and advanced materials research. Its compact dimensions allow it to pass through glovebox transfer chambers with diameters of 200 mm or more, helping users move the equipment between controlled environments and external work areas.

Built with a corrosion-resistant aluminum-alloy body, the equipment combines a clean appearance with straightforward maintenance. Precision slide rails help maintain alignment between the upper and lower cutting tools, supporting stable punching performance, extended service life, and consistent results under frequent laboratory use.

Key Features

• High-Precision Guided Cutting: Precision slide rails guide the cutting mechanism with high accuracy, helping maintain the required clearance between the upper and lower cutting tools. This design supports consistent hole quality and contributes to longer tool life.

• Accurate Round Hole Production: The standard punching configuration produces a 3 mm round hole with a hole-diameter accuracy of ±0.05 mm. Customized hole sizes are available according to process requirements.

• Reliable Hole Positioning: A dedicated positioning device helps operators place capacitor tabs correctly before punching. Hole position accuracy reaches ±0.02 mm, supporting reliable alignment during subsequent riveting operations.

• High Cutting Force: Cutting pressure is rated at ≥100 kg, providing the mechanical capacity required for stable punching of capacitor cell tabs during repeated preparation cycles.

• Compact Glovebox Compatibility: Measuring only 150 × 170 × 320 mm, this system can pass freely through glovebox transfer chambers with diameters of 200 mm or more, supporting controlled-atmosphere workflows.

• Flexible and Convenient Operation: The compact structure is easy to operate and quick to position at the workstation. Its small footprint supports flexible deployment in laboratory benches, assembly areas, and controlled-environment processing lines.

• Corrosion-Resistant Construction: The body is manufactured from aluminum alloy, providing a rust-resistant structure with a clean, professional finish. The material is well suited to equipment environments where simple cleaning and long-term appearance are important.

• Simple Residue Collection: A static-resistant ABS material collection box receives punched scrap and supports convenient discharge of residual material, helping maintain a cleaner work area.

• Easy Maintenance: The streamlined external design reduces unnecessary surfaces and makes routine cleaning, inspection, and maintenance more convenient for laboratory personnel.

Applications

Technical Specifications

The compact dimensions and dedicated positioning structure make the equipment practical for workstations where space is limited or where the punching operation must be integrated into a controlled assembly sequence. The 25 mm or greater cutting stroke provides sufficient travel for the punching action, while the cutting pressure of at least 100 kg supports stable operation during repeated tab preparation.

The standard 3 mm hole specification is suitable for the referenced capacitor tab riveting process. Where a different hole diameter is required, the cutting configuration can be customized. This allows users to adapt the unit to project-specific tab geometries or changing development requirements without replacing the entire processing platform.

The guided slide-rail structure is central to the machine’s performance. By controlling the movement of the cutting mechanism, it helps preserve the clearance relationship between the upper and lower tools. Correct tool alignment is important for clean punching, repeatable hole dimensions, reduced cutting inconsistency, and longer service life of the working components.

The integrated positioning device further improves operational consistency. Operators can place the tab against a defined positioning reference before actuating the punch, reducing placement variation between samples. With hole position accuracy specified at ±0.02 mm, the system supports the alignment demands of washer and end-cap riveting procedures.

The aluminum-alloy body provides a balance of low weight, structural practicality, corrosion resistance, and visual cleanliness. At 8 kg, the unit can be moved or repositioned more easily than larger industrial punching equipment. Its rust-resistant construction is also advantageous in laboratory environments where equipment may require frequent cleaning or exposure to routine process handling.

The static-resistant ABS collection box is designed to receive punched remnants and make scrap discharge straightforward. This feature helps reduce loose residue around the workstation and supports more orderly operation during repeated punching cycles. Together with the simple exterior design, it contributes to easier cleaning and maintenance.
