Roechling SE & Co. KG.

Company Profile



Richard-Wagner-Strasse 9, 68165 Mannheim, Germany

Business Overview

-The Company specializes in developing and manufacturing engineering plastic systems and components for multiple industrial sectors, including the automotive industry.

-The Company is organized into three divisions:

  • Industry Division
  • Automotive Division
  • Medical Division

-The Company entered into an agreement with Kasai Kogyo Co., Ltd to sell its plant in Wolfsburg-Hattorf. The 13,000 square meter plant in Wolfsburg-Hattorf, built in 2001, produces door and side panels for automobiles. However, Roechling Automotive has increasingly focused on systems and components for aerodynamics, propulsion and new mobility in recent years. The sale of the plant thus concludes a process initiated by the plastics specialist in 2011. The sale of the plant will affect about 170 employees. Kasai Kogyo is taking over the entire business operations and thus all employees. No job losses are anticipated. (From a press release on May 7, 2019)


-The Company is privately owned by members of the Roechling family.
