Coating Automation

It is almost inevitable to apply automation systems in order to make more efficient and economical production in surface coating processes. Nowadays, It is very difficult to meet various needs and intense demands in coating processes without automation systems. Coating facilities include a wide variety of equipment, different structures, techniques and coating processes. Therefore, different functions and equipment are compatible with process automation. Some of these equipment are:

• Transfer equipment;
• Coolants;
• Loading and unloading equipment;
• Moving and mixing parts;
• Tanks and special equipment;
• Ventilation;
• Filters;
• Rinsing equipment;
• Rectifiers;
• Chemical dosing systems;
• Heaters;
• Water treatment equipment.

Correctly programmed coating automations provide great advantages to the system. Efficient loading of facilities and bathrooms, less manpower, hygiene in the work environment, control of the desired coating quality, absence of human-induced errors, controlled chemical consumption, controlled increase in capacity, low energy consumption, time saving, changing order according to the process can be given as examples.

Dosing Equipment

Some components are reduced both electrolytically and by transport during operation in plating baths. The part (salts) of these reductions that decrease with transport is determined by analytical methods and given to the bath by allowing it to dissolve outside.Some of them are added when necessary by determining the ampere hour value. In ampere-hour controlled systems, the addition is made manually or with automatic dosing systems. Since the error rate will be higher in manual additions, systems called automatic dosing are recommended. Because both the lack and excess of the chemical affect the quality and efficiency of the coating. In addition, another reason why automatic dosing is preferred is cost. Additions left to the initiative of individuals may be made out of need or incompletely. In automatic dosing systems, dosing pumps are activated depending on the ampere hours and the chemical dosing of the solution is realized. However, even if an automatic dosing system is used in a facility, it must be checked that these pumps are in working condition and whether they are clogged or not. Nowadays, this conscious development has begun to be implemented in manual facilities as well as automated facilities.
