Velbert (Industriestr. 25-27, 42551)New on Amplifa
Zinc die casting from a single source since 1989
H.R.M. Metallverarbeitungs GmbH is a medium-sized family business founded in 1989 in Heiligenhaus, headquartered in Velbert. The company manufactures zinc die-cast parts and assemblies in component sizes ranging from about 1 gram to 3.5 kilograms – from prototype to large-scale series. The value chain includes in-house toolmaking including CAD/CAM design and mold-filling simulation, zinc die casting on twelve die-casting machines, CNC machining, surface treatments such as vibratory finishing and shot blasting, as well as assembly and kitting through to just-in-time delivery with Kanban logistics. Customers include sanitary engineering, medical and dental technology, electronics, machinery, equipment and plant engineering, the fittings and lock industry, the furniture and design industry, as well as solar and security technology. The company supplies customers throughout the European Union with a focus on southern Germany, Austria and Switzerland and is certified to ISO 9001:2015.

Materials and Processes
Zinc
Material for all die-cast parts, from filigree 1-gram components to complex components weighing 3.5 kilograms.
Zinc die casting
High-pressure casting process on twelve zinc die-casting machines, including the W200 Zn RC, for complex geometries in large-scale series.
Toolmaking
CAD/CAM-supported new construction and maintenance of die-casting tools with 5-axis milling machines, laser welding equipment and mold-filling simulation.
CNC machining
Precision post-processing of the castings, also on 5-axis milling machines and rotary transfer machines.
Vibratory finishing and shot blasting
Surface finishing for smooth, uniform surfaces of the castings.
Assembly and kitting
Pre-assembly of assemblies, labeling, marking and just-in-time delivery with Kanban systems.
