Our company
Galvanovna
Our private company located in Písek has been providing the electroplating services for more than 23 years, since 1995 when it was established. In response to the increasing demand of customers for surface treatment, our company has been extended and upgraded with new technologies. At present, there are several automatic lines available, both for barrel and rack electroplating, all of them utilizing COVENTYA technology.
Up to 1,000 t of material is treated in our plating lines each month. Quality inspection is guaranteed in compliance with the applicable standards and regulations and the quality management system according to which the company is certified.
Corrosion protection
With its automated barrel and rack lines, the company is able to provide efficient corrosion protection of metal parts.
Industrial application
The types of surface treatment offered by the company are used for example in the building, automotive or electrical industry. Galvanized steel may also be a solution for manufacturers of metal parts.
Electroplating
Electroplating is an electrolytic process applied in particular on electro-conductive materials (metals), in which a (zinc) metal anode is gradually dissolving in the bath. As a result, a layer of zinc is deposited on the metal parts that function as a cathode. Each plated batch of parts may be accompanied with a quality certificate as the customers require.
Once a quotation is completed, parts may be received for production (plating process), which takes three to seven business days (depending on individual orders). Plated parts may be accompanied with a quality certificate as requested and delivered by the company vans to a place indicated by the customer.

Surface treatment of metal
ZnNi alloy plating
Zinc-nickel
Parts are protected with direct passivation or plated with ZnNi alloy in automated barrel plating lines with annual capacity of 9,600 t using the latest COVENTYA technology. In the electroplating bath, a layer containing 85-88 % of zinc and 12-15 % of nickel is applied on the metal parts in three separate lines available. After plating, the surface may be improved with a black or transparent passivation, as per the customer request. Finally, the parts are lubricated to reduce the friction coefficient or sealed to achieve even higher corrosion resistance.
galvanic bulk
zinc plating
Drums or barrels are used particularly for plating smaller parts or fasteners that are loaded in electroplating barrels and transported to the plating line. Alkaline zinc plating in barrel may be complemented with two kinds of passivation – blue and thick-layer passivation as well as with lubrication. The annual capacity of the line is 1,000 t.

Rack plating
Thick-layer passivation, inhibition of tubular parts and sealing may be applied.
Acid bath:
maximum dimensions: 1,200 × 700 × 250 mm
Alkaline bath:
maximum dimensions: 2,700 × 1,200 × 300 mm
Procedures
Types of surface treatment
There are 4 various technologies available (zinc plating, ZnNi alloy plating, anodising, zamak passivation) as well as several colour variants of the surface treatment. Based on your inquiry, a quotation is prepared (depending on the specified thickness layer and yearly demand). Once the parts are received, they are processed within 3-7 days.
At the request of a customer, corrosion tests are made in an accredited laboratory.
- Alkaline barrel plating
- Very high corrosion resistance
- Automotive application
- Alkaline rack plating (bath dimensions: 2,700 × 1,200 × 300 mm)
- Acid rack plating (bath dimensions: 1,200 × 700 × 250 mm)
- Alkaline barrel plating
- Final layer or undercoat for wet painting or powder coating
- High corrosion resistance
Passivating and/or sealing the parts intended for barrel or rack plating lines.
Lubricates are used in particular for metal parts (as well as for plastic parts and elastomers) to reduce the friction coefficient and to protect the parts from wear and tear. In addition, the lubricants are not susceptible to dripping, which avoids any contamination of the immediate environment. Parts may further be protected with a sealant (especially Gleitmo and Finigard) to increase the corrosion resistance.
Anodising is provided in natural or black colour.

Quality inspection
To be able to deliver the service in the required quality, we are continuously improving, developing our procedures and implementing advanced technologies to provide services in the quality our customers expect.

- Quality policy
There are two X-ray devices available to measure the ST thickness and analyse the plating bath. The measured values may be stated in inspection certificates issued for any plated parts. For new projects, PPAP documentation may be provided.
Layer thickness is measured with X-ray fluorescence using Röntgenanalytik Messtechnik X-Ray ECO Compaq device. The quality management system is certified according to ISO standard.
Ecology
Caring for the environment
The company utilizes new advanced technological facilities that meet all the requirements on environmental protection and hygiene at work.
1995
In 1995 a new wastewater neutralization plant was commissioned and a PC system implemented to control the reactor for wastewater treatment.
2011
On February 28, 2011 reconstruction of the wastewater neutralization plant was completed.
2017
At the beginning of September 2017, an extension to the waste treatment plant was built.

About us
History
Václav Chmela – Galvanovna s.r.o. is a private electroplating company located in Písek providing surface treatment of metal parts, i.e. zinc plating, ZnNi alloy plating, chromating and anodising. Our customers may have the products delivered by our company vans.
On January 1, 1995, GALVA - Václav Chmela was established by privatization of the Elektropřístroj Písek galvanizing plant.
1. 1. 1995ESTABLISHMENT 
In September, 2006 a new automated rack line for zinc plating was commissioned.
1. 9. 2006NEW LINE 
In spring 2008, an automated barrel line for ZnNi alloy plating was constructed with the weekly capacity of 56 tons. It includes transparent and black passivation baths as well as a sealing bath and uses the advanced COVENTYA technology.
1. 5. 2008Barrel line 
In 2014, a second automated barrel line designed for ZnNi alloy plating was launched with the same weekly capacity as the first one, i.e. 56 t. The line has baths for transparent passivation or sealing and utilizes advanced COVENTYA technology.
1. 9. 2014SECOND BARREL LINE 
Finally, in 2017 a third automated barrel line was put in operation to further expand our production capacities. This ZnNi alloy plating line has twice as much capacity as the previous lines, involves baths for transparent passivation as well as sealing and uses the advanced COVENTYA technology.
1. 9. 2017EXTENSION OF THE COMPANY FACILITIES 
In summer 2018, another two automated lines were completed – barrel plating line (June 2018) and rack plating line (August 2018).
