About Kockzius Feinwerktechnik
Kockzius Feinwerktechnik GmbH is a family-owned company founded in 1982 with its headquarters in Grafrath near Munich. The company manufactures plastic parts using injection molding, mechanical precision parts, and injection molding tools—from prototype to large and small series production. The range of processes includes servohydraulic and electric injection molding with core pull, multi-component technology, turntable solutions, and overmolding of insert parts, as well as mechanical manufacturing using milling, HSC milling, turning, grinding, drilling, and EDM. Furthermore, Kockzius offers CNC-controlled laser welding of titanium, aluminum, and stainless steel, among other applications, for the repair of components and injection molding tools. The entire process chain, from CAD design (VISI) to feasibility analysis, assembly, packaging, and logistics, is performed primarily in-house, sometimes automated using robotics. Main industries are medical technology, automotive, electronics, consumer goods, sensor manufacturing, precision mechanics, automation, and regenerative materials. Manufacturing is performed according to DIN EN ISO 9001.
