18650 21700 Series Laboratory Cylindrical Battery Case Opening Machine

Product Overview

This laboratory cylindrical battery case opening machine is designed to remove the outer casing from sealed cylindrical batteries after the crimping process. It enables researchers to access the internal cell for inspection, material analysis, failure investigation, and research validation while maintaining controlled, repeatable cutting performance.

The equipment is supplied with tooling for 18650 cylindrical batteries and can be configured with additional molds for other cylindrical formats, including 21700 cells. Its compact construction, straightforward controls, and guarded operating approach make it well suited to battery laboratories, pilot research facilities, universities, and advanced materials testing environments.

Precision adjustment is supported by a micrometer with a 0.01 mm scale value, helping operators position the cutting operation accurately. The dedicated cutting blade uses tungsten carbide, while separate motor speeds for the blade and mold support stable and controlled case removal without damaging the cell housed inside the metal shell.

Key Features

• Interchangeable Battery Tooling: The equipment uses dedicated fixtures and molds for different cylindrical battery formats. Standard tooling supports 18650 cells, while optional tooling can be selected for other compatible sizes such as 21700.

• High Disassembly Precision: Controlled positioning and fine micrometer adjustment help separate the cylindrical casing accurately. The design is intended to avoid damage to the internal cell, supporting reliable sample retrieval and subsequent analysis.

• Tungsten Carbide Cutting Blade: The case cutting saw uses tungsten carbide for a durable cutting edge and dependable performance during repeated laboratory use. This material choice supports consistent interaction with cylindrical metal cases.

• Controlled Cutting Speed: The cutting blade motor operates at 1000 rpm, providing a defined cutting condition for repeatable case opening. A dedicated mold rotation speed of 320 rpm further supports coordinated processing.

• Simple Operator Workflow: The unit is designed for convenient laboratory operation without a complex processing sequence. Its practical configuration helps operators prepare, position, and disassemble cylindrical cells efficiently.

• Compact Laboratory Footprint: With dimensions of 700 mm in length, 320 mm in width, and 220 mm in height, the equipment occupies limited bench space compared with larger industrial processing systems.

• Safe and Reliable Operation: The structure is designed around controlled battery positioning and stable cutting action. This supports safer routine handling of sealed cells during research and inspection work.

• Flexible Research Utility: The system can be used for cell retrieval, post-crimping examination, internal component inspection, and validation work across battery development and materials research programs.

Applications

Technical Specifications

The standard configuration is intended for 18650 cylindrical cells and provides the basic tooling required for laboratory case opening. When a project involves different cylindrical battery dimensions, additional molds can be specified to match the required cell format. This modular tooling approach allows the same equipment platform to support broader battery research programs without requiring a separate machine for every cylindrical size.

The cutting system combines a tungsten carbide saw blade with a 1000 rpm blade motor. The mold rotates at 320 rpm, establishing a coordinated motion between the workpiece and cutting mechanism. These defined operating speeds provide a consistent mechanical basis for case removal and help operators repeat the same procedure across multiple samples.

Fine positioning is supported by a micrometer scale value accuracy of 0.01 mm. This level of adjustment is important when the objective is to remove the casing while protecting the internal cell. In laboratory disassembly, excessive cutting depth or inaccurate positioning can compromise the sample and reduce the value of subsequent inspection. Fine adjustment therefore contributes directly to sample integrity and repeatable research results.

The equipment operates from an AC220V 50HZ electrical supply and has a rated power of 0.2 KW. Its overall dimensions are 700 mm long, 320 mm wide, and 220 mm high, allowing installation in a laboratory or pilot-scale workspace where bench area must be managed carefully. The listed weight is 30 kg, providing a relatively manageable format for equipment placement and laboratory layout planning.

Why Choose This Product

• Purpose-Built for Cylindrical Cell Disassembly: The system is designed specifically for opening sealed cylindrical battery cases after crimping, rather than adapting a general cutting machine to a sensitive battery application.

• Protection of Valuable Research Samples: High-precision positioning, dedicated fixtures, and controlled cutting action are intended to minimize damage to the internal cell, preserving samples for inspection and analysis.

• Flexible Format Support: Standard 18650 tooling and optional molds for other cylindrical formats allow laboratories to expand testing capability as battery development requirements change.

• Compact Premium Laboratory Design: The practical footprint, 0.2 KW power requirement, and straightforward operating concept make the unit suitable for controlled laboratory environments and pilot research areas.

• Reliable Technical Configuration: A tungsten carbide blade, defined blade and mold speeds, and 0.01 mm micrometer scale value accuracy provide the mechanical control needed for repeatable case opening work.
