About ARNOLD
ARNOLD UMFORMTECHNIK GmbH & Co. KG, headquartered in Forchtenberg-Ernsbach, is a manufacturer of fasteners, cold-formed parts, series modules and processing systems and is part of the Würth Group. The company develops and manufactures custom fasteners for metal, sheet metal and plastics (including TAPTITE 2000®, REMFORM®, Sheetite®, Alufast®), complete fastening systems with system technology (Tooltec, Feedtec, Controltec) and cold-formed multifunctional parts with up to seven forming stages. The value chain includes toolmaking, double-stroke and multistage presses, thread rolling, in-house heat treatment, electroplating, friction element welding (Flowweld®) as well as metal 3D printing and technical cleanliness in accordance with VDA 19.1. Its main customers are the automotive and electrical industries as well as e-mobility, in particular for lightweight and multi-material applications. Production takes place at four sites in Germany; sales companies exist in France, the USA and China. In 2025, the company generated revenue of €276 million with 1,455 employees and produced 6.395 billion parts.
