about this location
welcome to Zwönitz
Since the foundation of Aalberts Surface Technologies GmbH Zwönitz in 1977 (formerly Galvanotechnik Baum GmbH), the company has established itself as a flexible, future- oriented contract processing company. Today, the Zwönitz site, with around 200 qualified and highly motivated employees, carries out mainly technically functional but also decorative coatings of the highest quality on an industrial area of 20,000 m². A total of eleven fully and semi-automatic machines are used in Zwönitz in the rack and barrel area. Every day we refine over 300 tons of metals.
State-of-the-art computer-controlled plant technology combined with qualified personnel and a profound organization ensure an optimized price and performance spectrum. Our portfolio in Zwönitz includes individual solutions on customer request as well as the latest processes in electroplating technology.

quality and know-how from Zwönitz
applications and fields of application
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.
fields of application
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. During electroplating, the deposition of the coating metal takes place as an alloy layer on a workpiece.
