ESCHA - a well-known manufacturer of plug-in connectors for sensor technology

ESCHA Bauelemente GmbH will celebrate its 30th anniversary next year. The company was founded in 1983 exclusively as a stamping plant, and the production of injection-molded parts was taken up in 1986. Today it operates two production facilities in Halver as well as its own separate logistics center, with some 500 associates and about 42 million EUR in sales in 2011. A new mold-making facility will be ready to move into shortly.

The company's General Manager, Dietrich Turck, comes from the Turck family, who are the majority shareholders of ESCHA. Its main market is Germany, but it is expanding vigorously into the European market as well. Thanks to a global network of distribution partners, its products are available worldwide. The company's key markets are in the automation industry and the mechanical and plant engineering sectors.

ESCHA's product portfolio is divided into 3 areas, "Tailor-Made", "Specials" and "Standard", with Tailor-Made contributing about 50% to total sales. With this high proportion of customized solutions as well as special solutions, ESCHA has achieved a unique selling proposition on the market and is known as a trendsetter for plug-in connectors for sensor technology. Examples of customized solutions are detergent-resistant or highly heat-resistant plug-in connectors, connectors with special data transmission functions or quick-connector technology, to name just a few.

The company's specific product range requires a high degree of innovative strength - ESCHA files numerous patent applications every year - as well as an extensive vertical range of manufacturing. Therefore training has top priority at ESCHA. ESCHA offers trainee positions for all trades and professions relevant to the company, such as industrial business management assistants, toolmakers, draftsmen, as well as plastics technicians and information technology officers. But further training for existing staff is offered on a continuous basis too. ESCHA also makes intensive use of WITTMANN BATTENFELD's training program.

In manufacturing its innovative products, ESCHA relies on innovative injection molding technology from WITTMANN BATTENFELD

In the course of expanding its production capacity at the Oststraße facility, ESCHA has invested in modern injection molding machines from WITTMANN BATTENFELD's HM series. These are actually hydraulic machines with clamping forces ranging from 65 to 180 t, consisting of 4 HM 65/60 machines, 3 HM 110/210 units and one HM 180/750. "The new injection molding machines have enabled us to improve the coordination of our entire pool of machinery. We have categorized our equipment into three sizes and laid out all machine models belonging to each category in a similar way. This enables us to freely combine the molds and machines from the same category with each other, which increases the flexibility and utilization rate of the equipment", says Jürgen Sikora, Head of Materials Management at ESCHA.

Due to the high proportion of customized products and consequently small batch sizes, short changeover times were a vital consideration in the selection of the machines to be newly installed. Repeatability in injection molding and correspondingly high product quality are equally important for ESCHA. The actual task was to realize the specifications laid down by ESCHA concerning shot weights and injection pressure by means of an appropriate machine concept. Fast delivery of the new equipment was also an important factor in its selection.

WITTMANN BATTENFELD was able to perfectly satisfy all of these requirements with its hydraulic machines. Especially the excellent changeover properties of the machines spoke in favor of WITTMANN BATTENFELD as a supplier. Moreover, the option of eccentric injection as required by ESCHA was implemented by WITTMANN BATTENFELD to the customer's full satisfaction through enabling the injection unit to move sideways.

The Head of the Injection Molding Department at ESCHA, Jochen Rüschenbaum, speaks very highly of the cooperation with WITTMANN BATTENFELD: "WITTMANN BATTENFELD has been flexible in fulfilling our requirements and wishes. Our specifications have been complied with in every respect." For instance, in addition to the option of eccentric injection mentioned above, a number of other customized adaptations were implemented, such as mounting several sockets which require a high level of safety for the machines, and the addition of high-temperature tubes and special water filters.

In addition to the machines from WITTMANN BATTENFELD, sprue pickers and temperature controllers were purchased from WITTMANN, thus utilizing the benefits of a well-coordinated overall package from a single source.


The machines of the HM series stand out above all by their modular diversity, ultimate precision and extensive range of options for virtually any application, which makes this series especially attractive for ESCHA. The machines also feature an extremely small footprint, thanks to their highly compact, extremely rigid 3-platen design. Further characteristics are low noise levels in operation and a service-friendly structure. A generously dimensioned mold space and low-maintenance linear guides are additional highlights of the HM series.


ESCHA is a leading supplier of connector and enclosure systems. For more than 25 years, the family-owned company has been engaged in developing and manufacturing its products in the city of Halver, located in the Sauerland region of Germany. As an innovation leader, ESCHA creates new products which drive the automation components market. On the basis of its standard products, the company designs customized connection technology and individual special solutions. With more than 500 associates, an extensive scope of engineering and a wide range of vertical manufacturing, ESCHA is extending its product portfolio continuously, independently and flexibly.
