About Willy Schulz
Firma Willy Schulz M. Maaz & D. Maaz GbR manufactures technical components, assemblies and complete devices to drawing in Wilschdorf near Radeburg in Saxony. Production includes CNC turning, CNC milling including 5-axis machining, and multitask machining on twin-spindle turn-mill centres. In addition, the company offers device construction and assembly manufacturing with the assembly of mechanical, electromechanical, electronic and pneumatic components, including functional testing with documentation. Materials machined include steel and steel alloys, aluminium, non-ferrous metals such as copper, brass, bronze, red brass and nickel silver, titanium, nickel and nickel-based alloys, special metals, and a broad range of thermoplastic, high-performance and thermosetting plastics. A historical focus is asbestos-free spark-arrester chambers for rail vehicles and switchgear, as well as solder frames for wave soldering of printed circuit boards. Customers come from mechanical engineering, vacuum technology, plant engineering, electronic device manufacturing, transport companies, nuclear technology, and luminaire and lighting technology. Lot sizes range from prototypes in pre-series production up to 10,000 pieces.
