Control and visualization systems - Automation

Control and visualization systems - Automation

We supply complete software control of the entire technological process to our plants. Automatic control of the line/plant operation reduces the amount of human labour required, increases plant efficiency and ensures consistent quality results. Despite the initial higher investment, automatic plant control is economically more advantageous than manual control due to higher productivity, consistent process quality and lower operator requirements.

The software solution is the result of development by our own programming team and is continuously being improved. We are therefore not dependent on an external control system supplier. For each customer we design an order-made control system to meet their requirements and ideas. We always run our systems on the latest version of the SIEMENS Simatic platform, which allows almost unlimited flexibility of the solution.

Thanks to our system, production can be planned efficiently. The system efficiently plans the use of production line capacity. The system performs simulations of future operations so that it can accurately plan individual line operations and schedule the passage of goods through the line to achieve optimum line utilization while adhering to all specified recipes. The system clearly displays all this information to the line operator on a touch panel at the line or on a PC. The operator thus knows exactly when and in what order the goods will be returned to him before the operation starts. The line operator can therefore focus primarily on the inlet and outlet sections of the line and leave the rest to our system, which takes care of the rest.

The system allows freely programmable recipes, as well as a custom recipe for each rack in the line. There can be multiple items in the line at one time, each with its own recipe. The automation system itself resolves any collisions and plans the optimal passage of goods through the line.

Our systems communicate with each other! The system controlling the surface treatment line communicates with the system controlling the WWTP and vice versa. This prevents production deficit and overcrowding at individual nodes. For example, the line knows exactly when it can discharge waste water to the WWTP. It also knows, for example, exactly how much DI-water it has ready in the treatment plant and can plan its production in advance so that there is never a shortage.

Powder paint coating line

Powder coating is an excellent choice for the protection and aesthetic treatment of surfaces in various industries. Its advantages include high resistance to damage, abrasion and corrosive effects, ensuring a long service life of the coating. Thanks to the electrostatic application of the powder coating, a perfect and uniform coverage with long durability can be achieved.

Another advantage of powder coating is its ecological and economic efficiency. The process is environmentally friendly, contains no solvents or volatile substances and minimises waste, resulting in reduced operating costs.

Due to its versatility and ability to coat various types of metal materials, powder coating is the ideal solution for many applications. It is a fast and efficient way to achieve a durable and aesthetic surface finish. The result is a quality and durable finish that meets the highest standards.


Our own powder paint coating line is equipped with

  • Surface pretreatment section (degreasing, phosphating, rinsing)
  • Powder paint coating section
  • Drying section
  • Hardening section

Thickness of coated layer is 80 micrometers (120g/m2)
