Battery PACK Assembly Lines & Laser Welding Machines
From cell testing and sorting to laser welding, pack assembly, and final inspection, SunLaser develops battery production equipment around your battery design, target output, and factory layout.
Battery Manufacturing Solutions
SunLaser supports battery manufacturers at different stages — from one critical welding process to a complete automated production line.
Battery Pack Line
Complete Module and PACK manufacturing solutions designed according to your cell, module, PACK and required production capacity.
Battery Welding Machine
Suitable for applications including battery terminals, busbars, CCS, module connections and PACK electrical connections.
Built Around Your Product and Production Targets
Whether you need a dedicated welding station or an integrated battery module and pack assembly line, start with equipment matched to your product and production requirements.
Equipment Designed Around Your Battery
Battery production equipment should match your actual cell dimensions, module structure, busbar design and PACK configuration.
Fixtures, tooling and process parameters are developed according to the product rather than forcing the product to fit a fixed machine.
Designed Around Real Cycle Time
Target output cannot be determined by one machine alone.
We analyze each production step, identify potential bottlenecks and design the line around your required PPM and production plan.
Stable Welding Starts Before the Laser Fires
Laser power alone does not determine welding quality.
Built for Today's Product and Tomorrow's Production
Depending on the project, adjustable fixtures, replaceable tooling, programmable recipes and modular production stations can be used to support future product changes and capacity expansion.
Lower Risk from Welding Trial to Handover
Every project is verified before it ships: the welding process, the machine and its safety.
Welding Trials Before Production
We evaluate your materials, joint design and required penetration, then validate the welding parameters before the equipment is built.
Factory Acceptance Testing
FAT verifies machine functions, welding results and the agreed production targets before shipment, so problems are found at our factory, not yours.
CE Compliance
Machinery designed to meet applicable CE safety requirements, with support for the conformity assessment process before delivery.
Precision at Every Stage of Battery Production
SunLaser integrates automation, positioning, laser processing, and inspection technologies to support consistent production quality.
