Laboratory Manual Cylindrical Battery Sealing Machine

Product Overview

This laboratory manual cylindrical battery sealing machine is designed for research sample preparation involving cylindrical batteries and cylindrical capacitors. Its hydraulic operating structure delivers strong, controlled sealing force while the two-stage sealing process improves edge flatness, dimensional accuracy, airtightness, and process consistency. The compact bench-scale format supports practical operation in space-limited laboratory environments.

The equipment is primarily intended for battery material research, cylindrical cell development, and cylindrical capacitor research. It is also suitable for small-batch trial production where dependable sealing quality is required without the footprint or complexity of a fully automated production line. The standard configuration includes one 18650 cylindrical battery sealing die set designed for two sealing operations, while other cylindrical battery die specifications can be selected when required.

A built-in pressure gauge allows operators to observe and control sealing pressure accurately during operation. The hydraulic drive produces up to 8 tons of force without vibration during sealing, helping reduce the risk of liquid leakage and supporting stable, repeatable results. A high-strength chromium steel structure, corrosion-resistant surface treatment, and precision die design provide a durable platform for demanding laboratory workflows.

Key Features

• Two-Stage Sealing Process: The two-stage sealing operation produces a flatter sealing edge, improved airtightness, higher dimensional accuracy, and better repeatability than a single forming action. This supports reliable preparation of research cells and capacitor samples.

• Hydraulic Drive With High Force Capacity: The hydraulic mechanism provides strong sealing force up to approximately 8 tons, enabling secure forming of cylindrical cell assemblies without vibration during the sealing process.

• Integrated Pressure Monitoring: An embedded pressure gauge allows the operator to observe sealing pressure directly and manage the applied force according to the cell format and process requirement. Standard operating pressure is typically around 80–100 kg/cm².

• Low-Force Manual Operation: The hand lever is designed for an operating force below 6 kg, reducing operator fatigue while maintaining direct control over the sealing cycle. The specially designed hydraulic structure makes manual operation more efficient.

• Precision-Engineered Sealing Dies: The die design supports accurate and reliable sealing formation. Japanese imported die material is used to help maintain forming performance and dimensional consistency during repeated laboratory use.

• Rigid Corrosion-Resistant Frame: High-strength chromium steel structural components provide a stable foundation for the sealing process. The surface receives environmentally considerate electroplating and spray treatment for long-term rust resistance.

• Compact Laboratory Footprint: Measuring 235 mm × 190 mm × 360 mm, the unit occupies limited bench space and can be placed inside a glovebox for controlled-atmosphere operation when required.

• Easy Maintenance and Operation: The straightforward manual configuration supports convenient setup, operation, inspection, and routine maintenance. Its compact construction is practical for laboratories that need flexible equipment access.

Applications

Technical Specifications

The standard 18650 die set is configured for two sealing operations, allowing the cylindrical enclosure to be formed in a controlled sequence. This arrangement is intended to improve edge formation and sealing consistency while helping operators maintain repeatable process conditions from sample to sample. When a different cylindrical battery format is required, alternative sealing dies can be selected according to the intended cell specification.

The integrated pressure gauge is an important process-control feature for laboratory work. Under normal cylindrical battery sealing conditions, the gauge reading is approximately 80–100 kg/cm². The equipment can reach a maximum pressure of 200 kg/cm², corresponding to approximately 8 tons of force, but higher-pressure adjustment should only be made after consultation with the manufacturer. This operating guidance helps protect the equipment, die set, and workpiece while supporting controlled process development.

The mechanical layout is optimized for direct manual use. The hand lever requires less than 6 kg of operating force, and the hydraulic structure is specially designed to reduce the effort required during sealing. This makes the unit practical for repeated laboratory operation while preserving operator visibility and control over the process. The hydraulic drive also avoids the vibration associated with less stable forming mechanisms, supporting cleaner and more consistent sealing results.

The frame uses high-strength chromium steel to provide structural rigidity during compression. Its electroplated and spray-treated surface is designed to resist rust, helping the equipment maintain a clean appearance and stable service condition in laboratory environments. The precision die construction contributes to accurate sealing formation, while the compact dimensions make the system easier to position near other cell assembly, material preparation, or testing equipment.
