About TRAWID
Martin Pfeil TRAWID-GmbH has been involved in the development and manufacturing of electronics and mechanics for industry and science since 1960 – guided by the motto 'Measure - Control - Regulate'. The company manufactures precision components and assemblies for single piece and small batch production, including magnetically pure coil systems (Helmholtz and Braunbek coil systems up to Ø 4 m), fully automatic viscosity measurement and control systems, pressure line observation systems, pneumatic level regulators, and multifunctional breakout boxes for D-Sub connectors up to 78-pole. Mechanical production includes a conventional machine park for turning, milling, stamping, grinding, welding, and sawing, as well as CNC manufacturing in a climate-controlled hall featuring identical three- to five-axis machining centers in gantry construction. All common materials are processed, including exotic metals, ceramics, and plastics. Assemblies for scientific experiments, space probes, and satellites are created in a dedicated cleanroom. The offering is complemented by an EMC test house, load tests, assembly, and a test field with long-term tests. Customers come from industry, science, geophysics, geology, aerospace, chemistry, printing, packaging, and logistics. The location is Giesen (OT Hasede near Hildesheim).
