Technical plastic parts from a single source
Enna Werk - Dr. Appelt GmbH & Co. KG (ENNA WERK) produces technical plastic parts by injection molding in small and large series. The company develops and designs simple and complex plastic tools in its own toolmaking department and produces everything from tool to finished plastic part from a single source. In addition, assembly of plastic products and electrical assemblies as well as surface finishing such as pad printing, hot embossing and ultrasonic welding are offered. Thermoplastic materials are processed, in particular PP, PA, PC and ABS-PC blend; optical plastic elements such as lenses for objectives are also manufactured. The company was founded in Munich in 1920 as an optical institute and has been based in Wegscheid near Passau since 1968, where production and administration are now located on approx. 3500 sqm (of which approx. 2500 sqm production space). Customers include companies from electrical engineering/electronics, automotive, medical technology, the photo/optics industry, smart home and the semiconductor industry.
