About Knaup Modellbau GmbH
Knaup Modellbau GmbH is a model manufacturing operation located in Witten, founded in 1991, with six employees. The company manufactures models in wood, plastic, and metal – from casting model construction with hand, machine, and core models, as well as permanent and lost wax models, to body models such as master, data control, cubing, and snap-fit models, up to architectural, functional, and design models. Additionally, CAD design, NC milling program generation with ZW3D, 3D scanning, target-current comparisons (as-built/to-be), and reverse engineering are offered. The machine park includes a 5-axis CNC machining center in portal construction with travel paths of 3650 x 2345 x 1200 mm, a milling machining center with HEIDENHAIN control and a table load of up to 4500 kg, as well as further machining centers and lathes. Customers come from the foundry industry, the automotive industry (body development), as well as architecture and design.

Additional services
Quality
Quality testing is carried out using a measuring table (1200 x 900 mm) as well as a portable optical 3D measurement system with feature accuracy from 10 µm; this allows for full surface target-current comparisons against CAD data.
