Laser process platforms for battery and energy production — validated in our Laser Application Center, then engineered into production systems that meet the throughput, materials and tolerances of real factory floors.
We don't ship standalone machines — we deliver complete production processes, backed by one shared process-control architecture. Each platform is sized for the customer's volume, geometry and integration environment.
Cell-to-tab joining with vision-verified consistency. Cylindrical, prismatic and pouch cells.
High-current copper & aluminium busbar joining with controlled thermal input.
Process-controlled surface preparation before joining. No abrasive media, no chemistry.
Cell-level intervention to recover yield without scrapping the pack.
What changes when laser welding is done right — measured against incumbent processes (resistance welding, ultrasonic, mechanical fastening) on the same assembly.
Numbers shown as X % are placeholders — populated with verified customer data per platform & application. RMA does not publish process outcomes without measured baseline & controlled trial.
From the Laser Application Center to the production floor — a single architecture, applied per joint and logged per cell.
Material trials, metallography, tensile testing. Welding parameters validated against the customer's actual stack-up before tooling is committed.
Vision detection of every joint. Mechanical pressing eliminates gap. Height measurement compensates assembly tolerances.
Focal position corrected per joint. Beam shaping and power profile selected for material pair — copper, aluminium, nickel, layered.
Process signals captured per weld. Every joint is logged — documented, reproducible, audit-ready.
ESS, mobility and industrial energy — six segments where joint quality and traceability decide whether the product ships.
Stationary storage modules — high-capacity packs where consistency and traceability define safety certification.
SEG · 02Energy systems for drones and unmanned platforms — low-mass packs, demanding repeatability and documentation.
SEG · 03Scooters and light electric vehicles — production volumes that need fast cycles without losing joint quality.
SEG · 04High-power handheld packs — thermal management at the joint defines battery lifetime.
SEG · 05Forklifts, marine, AGV — heavy-duty packs where uptime and reliability outrank everything.
SEG · 06Inverter and converter assemblies — precision joining for high-current connections and thermal stability.
