Manual Coin Cell Battery Crimping Machine

Product Overview

This manual coin cell battery crimping machine is designed for controlled laboratory sealing of coin cells and capacitor research samples. Its hydraulic drive generates high closing force with low operator effort, while the integrated pressure gauge allows users to monitor sealing pressure during each cycle. Precision tooling and adjustable height limiting help produce consistent, secure closures without unnecessary damage to the cell can or sealing cup.

The equipment is intended for battery material research, coin cell sample preparation, capacitor development, and small-batch factory trial production. With interchangeable tooling, it can also support battery disassembly, electrode sheet pressing, and battery powder pellet pressing. Its compact footprint allows operation inside a glovebox, making it suitable for air-sensitive materials and controlled-atmosphere workflows.

A rigid high-strength chrome steel structure, environmentally treated surface, and precision die construction support stable long-term operation. Safety-oriented features include an adjustable pressure limit, an internal pressure relief oil valve, controlled opening travel, and a mechanism that helps prevent short circuits during coin cell sealing. The result is a durable manual system for demanding research environments where repeatability and process control are essential.

Key Features

• Hydraulic Sealing Force: The hydraulic drive provides strong, vibration-free compression with maximum pressure up to 8T, supporting dependable coin cell sealing and helping prevent liquid leakage when the correct process conditions are used.

• Low- effort Manual Operation: The specially designed hydraulic structure keeps handle operation below 5kg, reducing operator fatigue during repeated sample preparation and small-batch production work.

• Precision Height Limiting: A high-precision positioning ring in the lower die controls the finished battery sealing height. This helps prevent excessive or unstable compression from damaging the sealing cup.

• Integrated Pressure Monitoring: The recessed pressure gauge provides direct visibility of sealing pressure, allowing operators to verify the process and maintain more consistent results across samples.

• Adjustable Pressure Protection: An internal safety relief oil valve allows pressure adjustment and supports an upper pressure limit. This reduces the risk of damage caused by accidental overpressure during manual operation.

• Mechanical Battery Ejection: A spring-loaded ejector center inside the upper sealing cup helps release a coin cell if it becomes stuck. Turning the top screw drives the cell out without requiring forceful disassembly of the tooling.

• Precision Tooling: The die uses high-precision positioning features and imported Japanese die material to support accurate forming, reliable closure geometry, and stable results over repeated cycles.

• Rigid Corrosion-Resistant Construction: High-strength chrome steel structural components receive environmentally friendly electroplating and spray treatment. The finished structure is designed to resist rust and remain stable in regular laboratory use.

• Controlled Valve Operation: The oil release handwheel has defined rotation limits in both directions. This helps prevent over-rotation that could dislodge the steel ball or sealing ring and cause oil leakage.

• Compact Glovebox-Compatible Design: The small overall size and straightforward manual controls allow the unit to be positioned inside a glovebox, supporting controlled-atmosphere battery assembly and research.

Technical Specifications

Operating Sequence

Place the coin cell in the lower die while the machine is open, position it in the locating recess, and place the negative side facing upward. Flatten and align the sample before tightening the oil release handwheel clockwise to its limited position. Correct positioning is important for maintaining consistent sealing and using the height-limiting system correctly.

To seal the battery, repeatedly move the manual handle up and down. The jack rises and applies pressure through the moving die until the tooling closes. For normal coin cell sealing, continue until the pressure gauge reads approximately 80-100 kg/cm2. The factory-adjusted pressure setting is intended for standard sealing conditions; special high-pressure applications should be reviewed before changing the setting.

After sealing, loosen the oil release handwheel counterclockwise by approximately half a turn. The sealing die opens automatically, allowing the finished cell to be removed. The handwheel's direction limits help protect the oil valve assembly from excessive rotation.

The sealing height can be tailored by loosening the four set screws on the side of the sealing limit nut. Rotate the nut to set the desired height, then tighten all four set screws before returning to production. This adjustment supports different research requirements while preserving controlled die travel.

Why Choose This Product
