Dieter Braun is valued by its customers for being able to deliver efficient solutions of above-average complexity, even for small- to medium-sized quantities and with variable lead times.The internationally active company achieves a smaller part of its turnover with components for machine and plant construction as well as for the household appliance industry. Dieter Braun has experienced strong growth since it was founded in 1993. The company has operations in its customers’ major production locations: in addition to its head office in Bayreuth, it has factories in the Czech Republic, the Ukraine, Mexico and China.

In Dieter Braun, we have found a company that reaps great benefits from the increasing number of intelligent components and automotive electrification.

annual demand growth expected in the market for cable manufacturing

Potential for development

Dieter Braun is active in the automotive market – an area that is experiencing fundamental growth but is also of a cyclical nature. For the cable assembly segment, an annual growth in demand of eight percent is expected over the coming years, significantly more than the growth rates of the automotive market as a whole. Dieter Braun is benefiting from the growing proportion of electrical and electronic components in vehicles and from the trend towards production outsourcing among original equipment manufacturers (OEMs) and suppliers. The company has used various applications to position itself in a field that will be vital in the future: e-mobility. This means that the company is now considered a key player for its customers in the automotive supply industry. To further develop the company, the technological and customer base is to be broadened, also through company acquisitions. Turnover is to return to the previous level after the significant decline due to the structural crisis in the automotive industry and the pandemic.
