0.0/5 rating (0 votes)


MSK-500-AR18650 is an auto grooving machine for 18650 cylindrical battery cases. It provides a continuous workflow for case batch loading - neck grooving - case unloading without dedicated labor. 


Advanced Features:

  • Efficient batch loading/unloading mechanism with case feeding conveyor
  • Horizontally positioned grooving blade ensures the most stable and accurate grooving
  • Micrometer assisted grooving depth & height adjustment
  • Ability to compensate the axial deformation of a cylindrical casing  
  • User-friendly human-machine interface with PLC touch screen control
  • Floor-Stand enclosure with transparent front & side openable windows allow clear process monitoring and adjustment
MTI has granted the patent 201120464651.8 for the Cylindrical Cell Automatic Grooving Machine MSK-500-AR18650 Series since July 2012.
Working Voltage 220V AC, 50/60Hz, three Phase
Max. Power Consumption 1KW
Air Pressure 0.5 MPa~0.8Mpa is required (Air Compressor is not included, please click here to order) Attention: If a gas cylinder is used instead of air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn the installation of a gas regulator.

Operation Video
Optional Function With the optional slurry SS reservoir and feeding pump, it can apply a thin layer of insulation coating on the "neck"  after grooving to further enhance the sealing quality between the cap and case body. This approach can prevent the electrolyte leaking due to the gasket aging on the cap. Please contact us for more details.
Application Notes
  • Customized die for other cylindrical cell types is available upon request
  • It is necessary to seal the cap of the cylindrical case by using the MSK-510-AR18650 sealing machine after grooving the opening end
  • Each type of cylinder cell can only be grooved specifically by the certain model of this equipment. Please select the type of cylinder cell in the Product Options drop box to check the model number and price for the corresponding grooving die of each cylinder cell type
  • Please check the chart below to order the cylindrical cases.
