95% of the tools and machines used in components manufacturing and serial production are developed and assembled internally by SJM.

We exclusively develop our production systems in-house, using the latest technologies, in order to account for the special manufacturing techniques that we use in our production processes.

That allows us to design efficient production processes, to take product-specific manufacturing steps into consideration, and to meet the required quality standards.

Our standardized production processes and manufacturing centers mean that most of our products can be manufactured at any of our production sites worldwide.

At SJM, we are proud to offer high-quality products. Constant quality controls and extensive tests are part of our everyday production work.

Our production capacity can be adjusted very quickly at our local manufacturing plants.

The experience and knowledge we have gained from many years in global and local sales help us meet our customers’ needs.

Many years of experience in international logistics, along with the use of local warehouses near our customers, ensure a smooth supply according to the customers’ wishes.
