The quality of each coating is always limited to the cleanliness of the underlying surface
The first treatment step for each workpiece consists in careful cleaning: Starting with degreasing, cleaning, pickling and rinsing up to phosphatizing and other steps required, we configure the complete equipment to prepare the surface for the actual coating process. As usual, our DURST systems are individually tailored to the corresponding site, and the scalable approach offers completely new possibilities for an efficient management of the working area. For optimum adaptation to the application in question, we select the appropriate system type:
Our cleaning cubicle may be used for small and larger workpieces. Originally it has been developed for large pieces – but equipped with a cleaning automat, it is practical for smaller items as well. This offers maximum flexibility for frequently changing part sizes.
Chamber Type Pretreatment System
If however a conveyor system is already in place, a chamber type pretreatment system represents the perfect solution. It can be operated manually or in automated routines and still features compact dimensions. As the entry and exit position of the workpieces is identical, these items can be placed everywhere within the building, also close to a wall.
Continuous Flow Pretreatment System
Continuous flow pretreatment systems, like chamber type models, are coupled to a conveyor system. Note that in this case entry and exit are at opposite positions, in order to speed up the process. This method is preferred when faster exchange intervals and higher utilization rates are desired.
Treatment of Waste Water
In order to save cost and raw material for pretreatment systems, professional waste water processing should not be forgotten. For this topic, Durst offers a qualified selection of units based on different working principles:
The resulting waste water can be guided through evaporators, coalescence oil separators, or subjected to chemical-physical methods. These units are operated in closed loop preventing liquid to escape, and enabling precise monitoring of the composition in each distinct purification stage. This way, a detailed analysis of the results is possible anytime.
