Consistent high precision is key for the manufacturing process at Otto Männer in Bahlingen, Germany, which is primarily known for its precise moulds and valve gate hot runner systems. To guarantee this precision, the mould-making experts decided to invest in a Techster 84 profile grinding machine from Amada Machine Tools Europe, said to be suitable for large parts but also for intricate machining tasks.

Männer products and services are used when it comes to the high-volume production of high-quality plastic parts. For this purpose, moulds with up to 128 cavities are developed, and they use the in-house valve gate hot runner system.

On the surface, a demand for close tolerances

Consequently, for profile and surface grinding, top precision is the general requirement when manufacturing mould and functional parts that are used as original parts and ready-to-install spare parts. “In case of replacement parts, we produce parts with an accuracy of 1µm,” Rudi Köchlin, the shop’s production manager explained.
