About BLEN Metalltechnik
BLEN Metalltechnik GmbH is a metal processing company founded in 1986 by Ruppert Blaum and Thomas Engel, based in Ötzingen in the Rhineland-Palatinate (Westerwald). With 33 employees, the company manufactures machined parts ranging from individual pieces to small and medium series up to mass production. The value creation includes CNC turning on 6-axis high-performance lathes (spindle diameter 6 to 80 millimeters), 5-axis CNC milling with travel paths of 800 x 800 x 800 millimeters, flat grinding, threading, and CAD/CAM programming. Furthermore, the prototype and tooling workshop produces die casting tools, injection molds, and forming tools. Through its subsidiary 3D-WW GmbH, BLEN has offered additive manufacturing using SLS and SLM processes for highly complex plastic and metal components since 2018. Quality assurance is carried out using 3D measuring technology and non-contact inspection methods according to ISO 9001:2015. Customers come from general mechanical engineering, the automotive and automotive supplier industry, medical technology, aerospace, architecture, packaging machinery, hydraulics, pump manufacturing, motorsports, and food machinery.
