Surface treatment of metals
Galvanic lines
For high-performance equipment, depending on the destination, customer requirements (level of automation, applied technology, etc.) and their spatial possibilities, solutions are proposed, to which the design of individual equipment and its assembly into technological units subsequently correspond.
Critical components that make up the machinery of the technology lines are designed to allow a high degree of automation (Siemens system), optimizing energy and chemical substances consumption. Adaptation of the technological equipment, handling on the input and output sections from small batches to large batch volumes common in the automotive industry is a matter of design and implementation.
Main technological components of galvanic lines
- input and output sections for hinged and bulk goods
- tank machinery including accessories for heating, cooling or clarifying registers, exhaust frames, supporting and current-conducting beds, current-conducting fittings and injector mixing
- GAMA manipulators (conveyors) including tracks
- electric or manual transport trucks
- drying equipment (tank, centrifugal)
- anode material dissolution station
- storage and regeneration tanks
- technological process control system
- plating drums
Galvastac stationary plating equipment is also designed for small series production with persistent manual transfer of metallized parts.
Galvanic rack lines
Rack lines are used for parts where their character or chosen technology (chrome plating, anodizing etc.) requires it. Their machinery part from the tank equipment through the transport of goods in the line to hanging up parts on transportable rods is then provided by our company based on specific requirements of users. Components of renowned manufacturers with wide service representation are used not only in the Czech Republic, but also in places of foreign deliveries, are used for individual elements.
We supply suspension lines for:
- zinc plating
- Zn-Ni
- copper plating
- nickel plating
- tinning
- chemical and electrochemical polishing
- chromium plating
- anodizing
- phosphating
- degreasing
- pickling
- passivation
- blackening, alkaline blackening of steel, etc.
Galvanic drum lines
Components which are intended for commonly used standard electrochemical surface treatments such as zinc plating, nickel plating, cadmium plating, silver plating, etc. and which, by their geometrical, mass or other properties, require this method of execution.
We supply drum lines for:
- zinc plating
- Zn-Ni
- copper plating
- nickel plating
- tinning
- phosphating
- degreasing
- pickling
- passivation

Waste water disposal
In the chemical and electrochemical surface treatment process, water is an essential component necessary for the successful operation of the operated technology. Water enters the process with certain requirements for its physical and chemical composition, goes through the process as a carrier medium for used chemical preparations and at the same time as a medium that rinses the bath deposits from the components. If it fulfils its function and is polluted by the content of process substances so that its further use would be detrimental to the surface treatment process itself, it is drained away. Due to significantly changed properties compared to those at the entrance to the process, it cannot be simply discharged into either the watercourse or the sewer. Here, purification function of the wastewater treatment station for rinsing water and concentrates is used as a technological set-up for collecting tanks, reactors, dosing units, sedimentation tanks, after-treatment lines, sludge filter presses and technological process control systems.
Depending on the amount of incoming wastewater and on the customer designation and requirements, basically two ways of solution are proposed, to which subsequently correspond the design of individual devices and their assembly into technological units working cyclically (batch-flow with shut-down reactors up to approx. 1m3/h) or continuously (with flow-through reactors up to approx. 10m3/h).
High-performance stations with outputs above 10m3/h are usually designed using ion-exchange lines.
