Precision toolmaking with EDM
Profiform Feinwerktechnik GmbH was founded in 1985 by Günter Spieckermann in Leopoldshöhe and is a specialist for precision manufacturing in toolmaking. The company manufactures complete injection molding and micro-injection molding tools including mold inserts, stamping and fine-blanking tools in progressive and modular designs, as well as complete aluminium die casting tools; in addition, individual parts and prototypes are produced. The core process is electrical discharge machining (EDM): with 20 wire and sinker EDM machines, including 5 systems for micro and ultra-precision machining, even exceptional materials are cut erosionally – micro-machining in the 1/10 µm range is a specialty. Manufacturing is complemented by profile and surface grinding, laser deposition welding, laser marking, as well as drilling, turning and milling. Customers include electronics, lighting and metrology, the automotive supply industry, medical and micro technology, as well as aerospace. All premises are fully climate-controlled with a temperature gradient of ± 0.5 K/24 h; a 24-hour manufacturing readiness complements the range of services.
