Whether it’s Mass finishing, Coating, Cutlery cleaning or Blasting technology: you can’t do without in-depth knowledge of process engineering. You can quickly get in touch with one of our process engineers in the Service department – often, a simple phone call is all it takes to solve the problem, as you have the benefit of our many decades of experience.
In most circulation systems, the same workpieces are always processed using, for example, the same lubricants. If you wish to alter the range of parts in this circulation system – for example, by processing different materials – please check with our experts by telephone beforehand. Even minor changes to the process can lead to problems, which we can help you avoid. At Walther Trowal, this telephone Service and our availability are an integral part of purchasing our products.
