The first important step in coating of metal surfaces is the pre-treatment, which has a major effect on the adhesion and resistance of the paint layer deposited on the parts. The objectives pursued during the surface preparation process are as follows:
• cleaning the surface of oils, greases, grease, rust and other impurities
• obtaining a conversion layer that ensures good adhesion of the paint layer
• prevent rusting under the paint layer
At the planning of the offered lines for pre-treatment we collaborate with specialized companies in the field of chemical preparation of surfaces, and we always take the requirements and requests of our customers in account.
Tracking and adjusting the control parameters – temperature, pH, chemical addition – are automatical.
The chemical substances used in such lines are biodegradable and ecological, produced by firms in the field.
Before designing, manufacturing and after assembly, commissioning ensures the execution of the quality tests, according to the requirements of the beneficiaries.
The pre-treatment system for surfaces allows mechanical and chemical preparation of surfaces and parts in a small quantity and with large dimensions.
It is the most simple and the cheapest method for pre-treatment.
The dip pre-treatment system consists of a chain of tanks and a hoist track which ensures the movement of the load between the tanks. The rigorous control of the temperature and time prescribed in the chemical data sheet, provides a well-cleaned surface and a proper adhesion of the paint layer.
The Equipment (tunnels) for preparing the surfaces through aspersion is used to pre-treatment of the parts which are transported by overhead conveyor, that is functioning in continuous flux and in paces with automated control of the technological flux preset (temperature, time) using ecological chemical substances.
The technological lines for cataphoretic (KTL or e-coating), anaphoretic and autophoretic (ACC) painting offered ensure a high resistance of treated surface against external factors, through a uniform and adherent protection layer and also to paint into the hard accessible points (corners).
Through metal coating processes, (galvanizing, anodizing, phosphating), the treated metal surface becomes resistant to corrosive agents. Metal coated parts can be painted with major efficiency, improving the degree of resistance of the paint layer in a corrosive environment.
Our devices (pre-treatment, powderpainting, liquidpainting lines, cataphoretic, anaphoretic, self-dispersing, metal coatings, galvanizing, anodizing, phosphating technological lines) are equipped with an absorption / exhausting system, and an air filling system, according to the healthcare and environmental regulations.
In order to remove the contaminant materials safely and in the proper quantity, it is possible to attach a continuous or hand-operated waste-water operating system.
After a pre-treatment of the parts, the paint film is applied.
The powder painting of the parts takes place in the spraying booth, in the electrostatic field with the help of the spraying gun.
Our powder painting lines can be automatic-continuous or in pace, or hand operated.
After the proper cleaning of the parts, the next step is the application of the paint.
The painting of the part takes place in the painting booth with the spraying aggregate.
In the painting-drying booth, painting with liquid paints and the drying of the parts is done. These booths are used for painting-drying cars, buses, wagons, agricultural machines, their parts, large pieces, etc.
The drying tunnel or oven is used for drying the surface of the parts after the washing operation (surface preparation) or to dry the applied layer of liquid paint.
The operation of the technological lines is controlled – controlled by means of a centralized control cabinet.
Technological processes are tracked on a touch screen monitor, where the phases of technological operations, technological parameters, possible disturbances, etc. can be tracked.
There is the possibility to record and print the technological parameters made in a logbook as well as the energy consumption.
Transportation systems for parts are made in accordance with the type of equipment required and the parts which is needed to be carried. The transportation systems are characterized by high durability, are very silent, easy to maintain, a wide range of speed sets, heat resistance up to 200-300ºC
Our parts transportation system can be classic or power & free, with continuous or in pace functioning.
The running path of the conveyors inside the technological line is strengthened onto its structure. Besides that the running path is strengthened by the polls of resistance structure.
In the installations for dip pre-treatment, installations for auto-painting, cataphoresis or anaphoresis, respectively immersion painting installations, the transport of the parts is accomplished by transloading units, technical cranes.
The floor conveyor systems we offer are hand-operated, mechanized and / or automated handling trolleys.
Their biggest advantage is, that the parts with large dimensions and weight do not have to be lifted very high from the ground.
