Tumbling is part of the craft

Perfect coating thanks to small parts coating

Tumble coating – often referred to in the industry simply as ‘tumble coating’ – is a small parts coating process used for the surface finishing of small parts produced in large quantities. It is used throughout industry wherever large quantities of small parts need to be coated with functional or decorative finishes.

All the benefits of
small-part coating
at a glance

Tumble coating is characterised by

  • uniform surfaces
  • high output per batch
  • automated process control
  • high cost-effectiveness

Minimum unit costs for small parts coating

Cost-effective Coating

A key advantage of small parts coating is its high cost-effectiveness. As large quantities of small parts are processed simultaneously, short cycle times and low unit costs can be achieved. Furthermore, automated process control ensures consistent coating quality and a high degree of reproducibility.

Finally, material handling is kept to a minimum: the parts do not need to be turned or hung on racks.

Uniform layer thickness

In tumble coating, the workpieces are placed into a barrel. Inside the barrel, the parts are continuously tumbled and evenly coated with the coating agent. The rotation ensures that the spray mist reaches all surfaces evenly.
