Buchen (Friedrich-List-Straße 3)New on Amplifa
Machining and finishing service for enclosures and technical parts
OBT Machining Technology is a business unit of Odenwälder Kunststoffwerke Gehäusesysteme GmbH based in Buchen (Baden-Württemberg). The company accompanies products from development and design with 3D CAD, via in-house mould and tool making with injection moulding tools for pilot, small and medium series, through to the manufacture of plastic and aluminium parts. The machining service includes CNC milling, thread milling, engraving, drilling, countersinking, sawing and punching as well as EDM with start-hole drilling and wire EDM machines for electrically conductive materials such as steel, copper, brass and aluminium. In the field of surface finishing, painting in customer colours, screen, pad and digital printing in photo quality up to 1800x1800 dpi, decorative films, laser marking and EMC aluminium coating are offered; assembly and kitting including component procurement round off the portfolio. Customers are primarily the electrical and electronics industry as well as medical technology, e.g. the qubeAIRFLOW ventilation sensor enclosure for SKILLQUBE.

Quality and metrology
The entire CNC machine fleet is equipped with Renishaw 3D touch probes, with which parts are measured in the X, Y and Z directions prior to mechanical reworking. This shortens setup times, reduces scrap and ensures consistent machining quality without expensive clamping fixtures.
