Your supplier today; your partner for the future!

The one-stop shop for all your sheet-metal processing and frame building

Dumaco Oss, previously Heurkens & van Veluw, specializes in metal processing. We supply sheet-metal, tube and pipe parts, with orders ranging from single pieces to welded assemblies. Our team of 130 people is armed with the vary latest and fastest laser-cutting machines, press brakes and welding robots.

More and more OEMs are profiling themselves as head-tail companies. They keep sales, engineering and assembly in-house but prefer to outsource the production of parts, shells and sub-assemblies to third parties. Dumaco Oss has responded to this development and is ready to relieve OEMs of a lot of work. Production is fast and efficient, which makes it possible to keep costs low. No request is ever too much for Oss. Every challenge demands its own approach. With this in mind, employees in Oss work in teams. Each team has its own specialism and serves customers from A to Z.

We use the Quick Response Manufacturing philosophy (QRM) to optimize our work processes. This enables us to deliver quality products fast and with high delivery reliability. Focus is achieved via the separate production cells for ‘Laser cutting + bending’, ‘Projects’, ‘Key Accounts’ and ‘Innovation’.

Independence is an important concept at Dumaco Oss. This is why we give our employees a lot of responsibility and freedom. Our specialists have years of experience and know exactly what works best in practice and where improvements can be achieved. So, we also give these employees the opportunity to implement their insights and ideas in their own teams.
