OPTIMIZATION OF PRODUCT PROPERTIES WITH APPROPRIATE SURFACE TREATMENT
Appropriate treatments help improve the surface properties of the product, like corrosion resistance or wear protection. Depending on the application, various
treatment methods may be used to alter the surface properties.
By choosing the right material and surface treatment, products can be developed containing properties of both the base material – lower weight, for instance –
and the altered surface – e.g., high strength – along with the corresponding benefits.
WE TAKE CARE OF THE PROCESSING, YOU GET THE FINISHED PRODUCT
All surface finishing that we do not execute ourselves is completed by our DIN EN ISO 9001:2008 certified partners, with whom we have accumulated very positive
experience through the years. Your advantage: we take care of the handling, you get the finished product.
OVERVIEW OF OUR MOST COMMON SURFACE TREATMENTS:
-
KOLSTERISING: Kolsterising is the surface hardening of austenitic, stainless steels, without losing the
corrosion resistance. Corrosion-resistant but wear-susceptible steels are hardened by creating a carbon-rich diffusion zone from the surface inwards with excellent toughness, but without
affecting the corrosion resistance.
-
ANODISING: Anodizing, also called eloxal process (electrolytic oxidized aluminum) creates an oxidized
protective layer on aluminum. As such, the protective layer is not applied to the work piece, rather it is formed by converting the uppermost layer of metal.
-
QUENCHING AND TEMPERING: With quenching and tempering, steel parts are quickly heated, then rapidly cooled
(quenched) and then annealed, creating a part with a high strength and yield limit as well as high ductility.
-
NITROCARBURIZING: Applying salt bath nitriding according to the Tenifer® procedure, a nitriding depth between
10-30 µm and a thin wear-resistant edge layer is obtained. During the process, atoms of carbon and nitrogen diffuse interstitially into the metal, creating better fatigue properties and
increased corrosion resistance.
-
CASE-HARDENING: By adding carbon (carburization) and subsequently hardening and tempering, parts are given a
wear-resistant edge layer. It is possible to partially protect parts to allow for subsequent machining.
-
SANDBLASTING: Sandblasting cleans rust, paint or other residue from the workpiece surface, providing a surface
perfectly suited for lacquer coating or electroplating.
-
VIBRATORY FINISHING: For deburring and smoothing after machining, we operate our own in-house vibratory
tumbling machine. Together with grinding stones or other abrasives and a suitable solvent, the workpiece is processed in a rotating or oscillating container. This reduces excess material and
irregularities.
Further surface treatments are available on demand.
