Fabrication, Assembly, Testing & Build-to-Print = Contract Manufacturing

Rethinking processes for assembly and parts production

There are many reasons to make use of our contract manufacturing. First and foremost, of course, it is a matter of economic efficiency. Shorter and shorter delivery times, lack of internal production capacities and rising personnel costs can be further reasons to consider outsourcing production.

Whether a single part or a full system Grenzebach understands the value each project has to our clients. At Grenzebach we treat every build-to-print solution as if it was our own design.
