Manufacturing products that satisfy even the highest customer requirements has been the source of Hawle Armaturen GmbH's motivation for over 40 years now.
Production:
Duktil Guss Fürstenwalde the company's in-house foundry, is where high-quality unfinished castings are manufactured. The cast material is then processed in Freilassing using the latest CNC production systems. Following an aggressive bout of abrasive blasting, the EWS coating - an epoxy powder coating manufactured using a fluidised bed sintering process - is melted onto the heated casting surface. The use of industrial robots during this ensures an even layer thickness (at least 250 µm*). Hawle even produces its own elastomer/plastic components required for the final assembly process. Before shipping, all products are subjected to a rigorous final inspection procedure.
