About Kreck Metallwarenfabrik
Kreck Metallwarenfabrik GmbH is a contract manufacturer for CNC sheet metal processing based in Dietzhölztal (Central Hesse). Founded in 1938, the family-owned company produces sheet metal parts and ready-to-assemble assemblies, from single parts and prototypes through to large-scale production. Its range of services includes CNC laser cutting with solid-state lasers (Fiber/TruDisk), CNC bending including automated bending cells, combined punch-laser processing, welding and joining (MIG/MAG), deburring and grinding, secondary processing as well as surface finishing. Materials processed include steel, stainless steel, aluminium, copper and brass, with sheet formats up to 3000 × 1500 mm. Series production includes sampling per VDA 6, 3D measurement, documented quality assurance, assembly and logistics. Customers are industrial companies from various sectors with high demands on dimensional accuracy, repeatability and delivery reliability.
