Maintaining a strong focus on product and process innovation

Motherson Sumi Wiring India Limited is continuously working towards meeting present and future customer requirements, focussing on weight and space reductions and productivity for wire harnesses, which continue to become bigger and more complex. 

We consistently develop and introduce new technological solutions, for internal combustion engine vehicles as well as electric and hybrid vehicles.

In addition, we continuously improve our manufacturing process, to support our customers with the highest-quality products at optimum costs. With evolving vehicle technologies and broad spectrum of options being offered by OEMs to their customers, the wiring harnesses are becoming increasingly complex. In order to efficiently produce these complex wiring harness solutions, we are digitising our manufacturing process even further. For example, we have introduced digital assembly boards, colour detection systems, component presence sensors and online work instructions, which simplify the processes at our wiring harness plants in India and help deliver even better quality.

MSWIL emphasise on thinking creatively to make all the processes simpler, efficient, and safer. We persistently challenge the current processes to improve and produce better quality products.
