3-component technology from WITTMANN BATTENFELD
Wirthwein Crimmitschau GmbH & Co. KG, Crimmitschau, Germany

Since February this year, Wirthwein has been producing technical parts for the automotive industry with 3-component technology at its plant in Crimmitschau. The equipment used is a MacroPower XL 700 from WITTMANN BATTENFELD.
Wirthwein Crimmitschau GmbH & Co. KG is a company of the Wirthwein Group founded in 1949 by Walter Wirthwein in Creglingen. What started off at that time with the production of octagonal wooden pegs for railroad superstructure is today a family-owned and owner-managed company with more than 3,500 workers on 22 production sites worldwide. The company’s entry into plastics processing took place in 1967 with the production of dowels for track fastening. Today’s product portfolio of the Wirthwein Group includes components and assemblies for the automotive industry, railroad superstructure, the electrical and household appliances industries, medical technology and interior construction.
In Crimmitschau, fan propellers and frames for the automotive industry have been manufactured since 1993, since 2012 in the name of the newly established Wirthwein Crimmitschau GmbH & Co. KG. Today, this company manufactures technically advanced components for the automotive industry with 120 associates on corporate premises of about 21,000 m², of which almost half is used as storage and production area, with fan propellers and fan frames still constituting the company’s core competences. The range of fans includes both axial ventilators for thermal motor control and radial ventilators for conditioning systems in cars. These components are very demanding in terms of tolerances. The balancing requirements for radial ventilators are particularly stringent, since here even the slightest imbalance will cause unpleasant noises in car interiors.
Wirthwein Crimmitschau uses a variety of technologies to manufacture its components, such as compact injection molding, physical foaming, multi-component injection molding, automation, fully automatic greasing and pre-conditioning of parts, right up to assembling complete structural components. Of the 33 injection molding machines operating at Wirthwein Crimmitschau and ranging from 250 to 15,000 kN in clamping force, nine have come from WITTMANN BATTENFELD. Since 2018, exclusively machines from the servo-hydraulic SmartPower series and the MacroPower series from WITTMANN BATTENFELD have been added. The matching parts removal robots have also come from the WITTMANN Group.
“The machines from WITTMANN BATTENFELD are less prone to failure than others, and in the event of any problems, these can very often be solved by telephone, or if not, the WITTMANN BATTENFELD engineers are also quickly on site.”
