History

Founded back in 1954 by Irmgard and Johann Renzelmann primarily for machinery trade, the J. & G. Renzelmann GmbH developed in the course of its history to become a recognized expert in grinding technology which now has some 15 employees.
Since 1985, the Bremer family business is run by brothers Jürgen and Gerd Renzelmann. Also dates from the 1980s, the membership of the Technical Association of German precision tool grinder (FDPW), where Gerd Renzelmann as a board member already takes over 10 years of responsibility.
Meanwhile, with Mario Renzelmann already the third generation of the family entered the business.

The company Johne + Co. started its operations in 1992 with the contract manufacturing of high quality brake calipers for the automotive industry and of difficult gear housing for mechanical engineering. To be permanently meet the needs of its customers for reliable precision and optimized production processes, the company soon developed their own, excellent quality tools.

In the following years was a consistent expansion of production and product range through the acquisition of Tela GmbH Company in Horb am Neckar and Förster Precision GmbH, today promoted company A + K Precision GmbH in Solingen.

This created over the past 15 years, a quality-oriented group of companies with worldwide contacts in the automotive industry, aerospace industry, and in the machinery and agricultural machinery segment.



Today, with around 160 employees in the current year, the Group achieved a turnover of over 18 million euros.The company supplies more than 2,000 customers internationally, in which the three companies in the group are listed. Due to high investments in the areas of product quality, quality assurance and service quality, the Group has established itself in a continuous process as a reliable point of contact within the industry. In order to maintain this reputation, the group now has its own certified auditors and a number of its own patents.
