Welcome to KLEIN Stoßwellentechnik GmbH

The Company

In 1992, after completion of the first successful tests with the prototype of a CERABITE® shock-wave plant, development engineer Reinhold Thewes founded the Pulstec Stoßwellentechnik GmbH. The first production plant was installed at Edelstahlwerke Schmees, Langenfeld, Germany, in 1994. Since then, this plant has always been in operation with the task of removing full ceramic cores out of highly complex inner geometries of high-grade steel castings. In 1996, the first plant for large-scale series production in the automotive industry was installed at BMW Landshut foundry. Each time the type of the cylinder heads produced with the Lost Foam process was changed, the CERABITE® shock-wave plant was adjusted, too, so that also this plant is still running today in series production at the same production site. Until 1997 the Pulstec Stoßwellentechnik GmbH was licenser for the plant manufacturer Alb. KLEIN GmbH & Co.KG.

In January 1998 the company name was changed to KLEIN Stoßwellentechnik GmbH. Since then, the company has turned out to be an internationally operating manufacturer supplying complete turn-key plants especially for the automotive industry. Until November 2014, more than 6.5 million cylinder heads and motor blocks have been cleaned with the CERABITE® shock-wave process in the USA alone (more than 13.5 million worldwide).

Since 2002 KLEIN Stoßwellentechnik GmbH has also been developing custom-made plants for high-speed sheet metal forming with the Hydro-Pulse-Forming shock-wave process.

The service for our customers includes tests in our laboratory, turn-key commissioning up to preventive maintenance at the installed plant.

Since October 2018 KLEIN Stoßwellentechnik GmbH is a 100 % subsidiary of KLEIN Anlagenbau AG. With this takeover KLEIN Anlagenbau AG extended their competence in the sector of foundry equipment. In February 2019 both companies moved into their new company premises in 57258 Freudenberg, Obere Hommeswiese 53 - 57.
