COENG TWSL-300 3-in-1 18650 Battery Assembly Machine
The COENG TWSL-300 is a 3-in-1 battery assembly machine for 18650 cylindrical cells, combining insulation paper sticking, cell testing and automatic spot welding. The listed configuration supports a 10-cell combination, nickel sheet thickness of 0.08–0.12 mm and insulation gasket thickness of 0.25–0.5 mm. With a specified 220 V / 50 Hz supply, 2.4 kW total power and 0.4–0.6 MPa working pressure, it gives purchasing teams and project engineers clear starting points for equipment selection. Share your cell samples, pack drawing, materials and acceptance requirements to request a configured quotation.
Bring three battery assembly tasks into one equipment set. The COENG TWSL-300 combines insulation paper application, testing and spot welding for 18650 battery pack production. Its two-station arrangement includes orange material hoppers, local control screens, a vertical application assembly and a horizontal welding workstation. White equipment cabinets, caster wheels and adjustable leveling feet support positioning within a production workspace. For procurement teams, engineering contractors and equipment importers, selection starts with matching the machine to the actual cell, interconnect material, battery layout and production conditions.
The insulation paper sticking function applies insulating material as part of cell preparation. The listed insulation gasket thickness range is 0.25–0.5 mm. Review the material drawing, thickness, adhesive specification and cell contact area during sample evaluation so the selected process matches the intended assembly.
The equipment includes a testing function. Define the required test items, limits, rejection rules and result-recording scope in the technical agreement. Matching these requirements to your incoming-cell controls helps purchasing and quality teams compare equipment proposals on the same basis.
The battery spot welding machine function is specified for 0.08–0.12 mm nickel sheet, with nickel sheet welding position accuracy of ≤0.2 mm. Confirm material grade, sheet geometry, electrode arrangement and the pack drawing during process review. Agree weld inspection and acceptance methods using the intended production samples.
The listed configuration uses 18650 cells in a 10-cell combination. The specified changeover adjustment time is ≤15 minutes. Review the tooling scope, adjustment procedure and first-piece checks for your intended product before comparing changeover performance across quotations.
Use the process specification as the basis for technical comparison. Align cell format, pack geometry, insulation material and welding requirements first, then compare the machine configuration, tooling, acceptance scope and commercial terms. This makes an equipment quotation more useful for production planning, integration and import procurement.

The welding-speed figure uses the source unit PCS/h. Define the counted piece, product layout, material, operating conditions and inspection criteria in the acceptance plan. Validate sustained output with the actual samples before using it in factory capacity calculations.
Evaluate the TWSL-300 for power bank pack projects, compact 18650 battery assemblies and OEM battery production requiring these three assembly tasks. Suitability depends on the actual pack layout, materials and agreed quality criteria. A production project should also define upstream cell preparation and downstream pack operations, including any additional assembly, protection-board integration, enclosure work and final testing required by the finished product.
The listed specification is for 18650 cells and a 10-cell combination. Provide the cell drawing and pack layout with your inquiry. Any different cell size or configuration should be reviewed and confirmed in writing with the required tooling before ordering.
The published parameter is welding speed >1800 PCS/h. It should be evaluated against an agreed definition of PCS and the actual process conditions. Completed-pack output also depends on the pack design, loading, testing, inspection and other production operations.
The listed supply is 220 V / 50 Hz, total power is 2.4 kW and working pressure is 0.4–0.6 MPa. Share the destination electrical standard and available compressed-air conditions. Confirm phase, connection, air consumption, installation space and utility interfaces in the final equipment specification.
Send the nickel material specification, sheet thickness, insulation drawing and production samples. The listed windows are 0.08–0.12 mm for nickel sheet and 0.25–0.5 mm for insulation gasket thickness. Agree sample evaluation and quality criteria before equipment acceptance.
Request an itemized machine and tooling scope, drawings, utility requirements, acceptance plan, applicable destination-market documentation, packing details and delivery terms. Define installation, training, spare parts, warranty and technical support responsibilities in the commercial agreement.
The TWSL-300 combines three battery assembly tasks. Define the full project process separately, including any additional preparation, assembly and final testing steps needed for the finished product. Share the complete process map when reviewing integration into a wider battery pack assembly line.
Provide the cell type, pack drawing, material specifications, target output, destination and acceptance requirements. Ask for quotation scope to identify tooling, options, testing, documentation, packing and delivery terms separately, so purchasing can compare offers against the same specification.
