Wallbox production ramping up at Kontron: How the TS2plus transfer system from Bosch Rexroth is revolutionising e-mobility manufacturing. With a 50-second cycle time, our Certified Excellence Partner FMT Flexible Montagetechnik GmbH demonstrates how modern transfer technology is driving electric mobility forward.
How the TS2plus transfer system from Bosch Rexroth is revolutionising e-mobility manufacturing
The growing demand for charging infrastructure for electric mobility presented Kontron, an electronics manufacturer with expertise in plastics based in Leipzig, with new challenges. The aim was to develop an assembly line capable of producing wall boxes in a wide variety of designs and in large quantities. The target was an output of one wall box every 50 seconds. In order to keep up with international competition and establish this production in Germany, the focus was on efficiency through a high degree of automation while complying with automotive standards. This also required the seamless integration of the assembly line into the plant's existing Manufacturing Execution System (MES).
Solution: Modular assembly line with TS2plus
The system uses the TS2plus transfer system in a two-stage design with vertical connection via lifts. The workpiece carriers (640 × 640 mm) are universally applicable and equipped with modular holders, enabling flexible product processing.
The overall system at a glance clearly shows its dimensions: the arrangement of the various workstations, the consolidation of material flows and the integration into the existing factory MES demonstrate the high level of expertise of the FMT design team (image source: FMT).
Key technical data:
• Area: 34 × 18 m
• Cycle time: approx. 50 seconds
• Operation: three-shift system, 5 days/week, 50 weeks/year
• 11 assembly workstations (HAPs) + laser cells, testing stations and packaging unit
Assembly and testing processes in detail
The line combines manual, semi-automated and fully automated stations. Assembly takes place step by step at manual workstations, followed by high-voltage and end-of-line testing. After successful testing, the type plate is applied by laser and the product is transferred to packaging. NIO products are automatically ejected for reworking.
Digital networking and process reliability
The system is fully integrated into the existing factory MES. All relevant parameters – from assembly and testing to labelling – are controlled, monitored and documented in real time. This enables complete traceability and supports quality assurance in accordance with DIN EN ISO 9001:2015.

Packaging solution included
The packaging line comprises three packing stations with manual roller conveyors, storage areas for cardboard blanks and accessories, and a height-adjustable loading station for pallets – all integrated into the overall process.
Conclusion: Local expertise for global technology
The success of the project was largely based on the professional implementation by our partner FMT on site – as a general contractor with comprehensive responsibility. As a Certified Excellence Partner of Bosch Rexroth, the company combines proven Rexroth technology with local engineering expertise – a quality standard that Bosch Rexroth guarantees worldwide through its global partner network.
