Overview
About Droigk Formenbau GmbH
Who we are
Droigk Formenbau GmbH has been manufacturing high-precision mould components and neck rings for the glass industry for more than 60 years. Building on this extensive experience in precision tool making, we also offer our expertise to other industries: complex turned and milled parts, demanding functional surfaces, as well as single-item and series production. Our range of services includes 5-axis machining, complete turning and milling, repair and refurbishment of tools, as well as the remanufacturing of spare and special parts. We work with tool steel, stainless steel, cast iron, and other wear-resistant materials, achieving high dimensional accuracy and surface quality. Our strengths: complex geometries, high-precision functional surfaces, short-term production, repair and spare parts manufacturing, as well as flexible solutions for special applications — for mechanical engineering, hydraulics, plant engineering, and other industries.
