Coin Cell Electrode Sheet Punching Machine

Product Overview

This coin cell electrode sheet punching machine is a compact manual die-cutting unit designed for punching, blanking, and forming round specimens from thin battery materials. It is intended for precise preparation of electrode discs, separator discs, and other sheet samples used in coin cell research. With interchangeable dies, the equipment supports multiple punching diameters while maintaining a small footprint that fits efficiently into laboratory work areas.

The unit is suitable for positive electrode sheets, negative electrode sheets, separator paper, and comparable thin materials with thicknesses from 0.005 to 0.5 mm. It serves battery research laboratories, university materials science departments, pilot-scale cell development teams, and laboratories preparing samples for coin cell assembly. The compact design also allows the equipment to pass freely through glovebox transfer chambers with a diameter greater than 200 mm.

A high-precision slide rail guides the upper punch during operation, helping the equipment deliver accurate cuts without burrs, flashing, or visible indentation when used with appropriate materials and dies. Its corrosion-resistant body is designed for long-term laboratory use, while the simple mechanical operating method supports quick setup, straightforward cleaning, and dependable repeated sample preparation.

Key Features

• Precision Slide Rail Guidance: The upper punch is guided by a high-precision slide rail, helping maintain controlled vertical movement and accurate alignment between the upper punch and lower die.

• Clean Punching Performance: The cutting structure is designed to produce punched samples without burrs, flashing, or indentation, supporting consistent electrode and separator preparation for downstream coin cell work.

• Wide Material Thickness Range: The equipment can punch battery materials with thicknesses from 0.005 to 0.5 mm, covering thin positive electrodes, negative electrodes, separator paper, and related sheet materials.

• Interchangeable Die Sizes: Standard and optional die sizes allow the same unit to support different specimen diameters. The available range extends from 8 mm to 24 mm according to the selected configuration.

• Compact Laboratory Format: With dimensions of L110 x W150 x H235 mm, the equipment occupies limited bench space and is easier to position in laboratories with restricted working areas.

• Glovebox Transfer Compatibility: The compact body can pass freely through glovebox transfer chambers with a diameter greater than 200 mm, supporting material handling in controlled-atmosphere environments.

• Simple Manual Operation: The punching process uses a hand lever. The operator places the material on the lower template and moves the lever to drive the upper punch into the lower die.

• Corrosion-Resistant Construction: The body is manufactured from corrosion-resistant material to resist rust and preserve a clean, professional appearance during extended laboratory service.

• Easy Cleaning and Maintenance: The compact structure and straightforward mechanical design make routine cleaning, inspection, and maintenance convenient for laboratories with frequent sample preparation requirements.

Applications

Technical Specifications

The standard configuration uses a 14 mm punching die, while other die diameters can be selected within the 8 mm to 24 mm range according to the customer’s required specimen size. The common die options include 8, 10, 12, 14, 15, 16, 17, 18, 19, and 20 mm. This selection supports common laboratory requirements for round electrode and separator discs while leaving room for application-specific configurations.

The applicable thickness range is an important selection factor for battery laboratories. Materials should fall between 0.005 and 0.5 mm to remain within the stated operating scope. This range includes many thin electrode coatings, current collector-based sheet samples, separator papers, and experimental materials used during coin cell development. Before ordering, buyers should confirm the required die diameter, material thickness, and sample geometry so the configuration matches the intended process.

Operation is direct. The material to be cut is positioned on the lower template, and the hand lever is moved to drive the upper punch downward into the lower die. The material is separated by the punching action, after which the material tray can be removed to collect the finished pieces. This arrangement gives laboratory personnel a clear and accessible method for loading material, completing a cut, and retrieving the punched sample.

The 25 mm punching stroke provides the specified vertical travel for the upper punch. The high-precision slide rail helps guide this movement and supports alignment between the upper and lower tooling. Correct die selection, proper material placement, and appropriate operating technique remain important for obtaining the intended cutting result and maintaining tooling performance over time.

The compact external dimensions make the equipment useful where bench space is limited. The body measures 110 mm in length, 150 mm in width, and 235 mm in height. Its 6 kg weight allows laboratory teams to position or relocate the unit as required, while the compact geometry also supports transfer into glovebox environments that provide a chamber diameter greater than 200 mm.
