About Härterei Reinhard AG
Härterei Reinhard AG is a contract heat treatment company in Niederwangen near Bern, which emerged in 1959 from a family business with a tradition in metalworking. The company treats workpieces from metalworking trades and industrial companies – from single parts to series production. The range of processes includes heat treatments such as hardening, case hardening, tempering, carbonitriding, induction hardening, tempering, annealing, cryogenic treatment as well as, since 2024, nitriding and nitrocarburizing on a Nitrex system. The heat treatments are complemented by surface processes such as blackening, blasting, pickling, straightening, washing and brazing, as well as laboratory analyses, testing, consulting and logistics including transport. The company is owner-managed and has been ISO 9001 certified since 1998; in 2023 a new washing system and an ERP system, and in 2025 a nitrogen generator for energy savings, were commissioned.
