Pneumatic Laboratory Coin Cell Crimping Machine

Product Overview

This pneumatic laboratory coin cell crimping machine is designed for preparing sealed coin cells and capacitor samples during laboratory battery materials research. Its fully pneumatic operating principle provides a practical, repeatable sealing solution without electrical power, while the precision die assembly supports controlled closure of coin cell housings. Adjustable sealing-height control helps protect the cell and sealing cup when pressure conditions vary.

The equipment is suitable for battery R&D laboratories, capacitor research, university materials laboratories, and limited small-batch factory production. With interchangeable tooling, it can also support coin cell disassembly, electrode sheet pressing, and battery powder pellet pressing, extending its value beyond a single assembly operation.

A robust chromium steel structure, protective surface treatment, precise positioning, and dedicated safety features support dependable operation in demanding research environments. The exhaust arrangement can be connected externally through KF40 or similar components, helping maintain a controlled glove box atmosphere when the unit is used inside an inert-gas enclosure.

Key Features

• Fully Pneumatic Operation: The unit operates without electrical power, simplifying installation and reducing dependence on electrical connections inside laboratory work areas or glove boxes. A manual pneumatic valve controls the opening, closing, and pressure application sequence.

• Controlled Sealing Height: A high-precision locating ring in the lower die establishes the battery position and limits the final sealing height. Operators can adjust the height stop through the locking nut and side set screws to achieve repeatable closure while reducing the risk of excessive pressure damaging the cell or sealing cup.

• Reliable Battery Ejection: A screw-and-spring ejector mechanism is integrated into the inner ring of the upper sealing cup. If a sealed coin cell becomes stuck, turning the top screw forces the cell out of the die for easier and safer removal.

• Precision Die Formation: Carefully designed sealing dies help produce accurate, reliable, and secure closures. The standard tooling handles 20-series coin cells, while selected die components can be changed for additional cell sizes.

• Flexible Gas Supply: The system can use either compressed air or inert gas cylinders, including argon and nitrogen. Inert gas is appropriate for controlled battery assembly, while compressed-air use is not recommended inside a glove box because it may compromise the glove box atmosphere.

• External Exhaust Connection: A dedicated exhaust port allows discharge to be routed outside the glove box through KF40 or equivalent hardware. This design helps limit unwanted gas release into controlled working environments.

• Adjustable Sealing Pressure: A manual regulating valve allows the operator to control the working pressure. The recommended operating pressure is 0.7 MPa, supporting consistent sealing conditions across repeated sample preparation cycles.

• Durable Steel Construction: High-strength chromium steel structural components receive environmentally considerate electroplating and spray treatment. The treated surfaces are designed to resist corrosion and maintain stable operation during long-term laboratory use.

• Battery Short-Circuit Protection: The equipment incorporates a function intended to help prevent short circuits during coin cell sealing, supporting safer handling of active battery samples when the specified loading orientation and operating procedures are followed.

Applications

Technical Specifications

The standard configuration is intended for 20-series coin cells. Additional sizes require the corresponding compatible die components and should be selected according to the cell format and intended operation. Gas supply pressure, loading orientation, sealing-height adjustment, and exhaust routing should be verified before processing active battery samples.

For routine operation, place the cell level in the lower locating recess with the negative face upward. Actuate the manual valve to switch the gas path and raise the moving template until the dies close. After sealing, reverse the valve so the template descends and the tooling opens automatically. If removal resistance occurs, use the upper screw-and-spring ejector mechanism rather than applying excessive force to the cell or die.

Why Choose This Product

• Built for Repeatable Research Production: Controlled positioning, adjustable sealing height, and manually regulated pressure help laboratories produce comparable samples across material batches and test programs.

• Premium Mechanical Construction: High-strength chromium steel components and corrosion-resistant surface treatment provide the rigidity and durability expected from equipment used through repeated development cycles.

• Efficient Glove Box Integration: Flexible argon or nitrogen supply and an externally connectable exhaust port support controlled-atmosphere workflows while avoiding a mandatory electrical connection.

• Broader Laboratory Utility: Interchangeable tooling can extend the unit from standard coin cell sealing to selected cell disassembly, electrode pressing, and powder pellet preparation.

• Practical Operator Protection: The height-limiting structure, assisted cell ejection, short-circuit prevention function, and defined loading and operating procedures support safer, more controlled sample preparation.
