Message from our CEO
Committed to Making a Difference to Industry and Society
Since its founding in 1960, KSK has specialized in manufacturing vehicle drivetrain components by constantly enhancing its technological and manufacturing capabilities through continuous improvement in its efforts to become a company that can have a significant contribution to society, as well as a company where all employees are glad to work.
The automotive industry is in the midst of a once-in-a-century transformation with the speed of this change accelerating at an unprecedented pace. Rather than viewing these changes as a threat, we see them as an opportunity to create and pioneer new product areas beyond the conventional boundaries and will continue to develop high-quality, technologically advanced products that create new value while at the same time doing what’s necessary to tackle the important issue of global warming.
Faithful to our motto of "Manufacturing based on wisdom and the five senses," we will continue to improve, create the conditions for a stronger KSK, and strive to be a company where every employee has a smile on their face and which is regarded as a trustworthy and much-needed partner by customers and local communities.
Thank you for your continued support.
