efficient surface treatment - your benefits at a glance
The advantages of the galvanic processes* in Zwönitz include:
- High corrosion protection
- Wear resistance
- Higher electrical conductivity
- Good temperature resistance
- Chemical resistance
- Improvement of friction and sliding properties
- Production of a good adhesion primer for oils, varnishes etc.
- Good flanging properties of the layers
- Good layer thickness distribution, creation of well leveled layer
*dependent on the type of coating
These properties enable us to coat customers’ components at the Zwönitz plant in accordance with all current standards and specifications, thus improving the product properties of the metals.
The automotive industry is the most important industry for our plant in Zwönitz, accounting for approx. 90% of our production. The zinc-nickel coating is of utmost importance here, thanks to the extremely high corrosion protection for aggregates, fasteners and chassis
quality
Thanks to the most modern plant technology with fully and semi-automatic barrel and rack systems, metal parts up to a maximum single component weight of 15 kg can be coated in Zwönitz in the most diverse geometries. We can also guarantee reliable surface treatments in large quantities. The maximum goods window in the rack area is 2.30 m x 1.20 m x 0.45 m.
