TECHNICAL BROCHURE Shotblasting of aluminum profiles previous to anodizing Cym Materiales SA has developed a line of equipment for continuous shotblasting of aluminum profiles previous to the anodizing process. Shotblasting is a technique of superficial treatment by impact that can achieve an excellent degree of cleaning and simultaneously a correct surface finishing. The impulsion of the abrasive is done by means of centrifugal turbines, a technique that is the most economic method among the curre nt techniques of surface preparation that does not pollute the environment. The functioning of the shotblasting turbines is similar to a centrifugal pump. The shotblasting machines for aluminum profiles use multiple turbines positioned in a way that the abrasive reaches all surfaces to be shotblasted homogenously.

Advantages of the use of the shotblasting process previous to • Fast turnover of the initial investment (between 1 and 3 years) • Recovery of profiles that are out of standard o Recovery of second selection materials. o Elimination of superficial stripes because of a failure of the extrusion mold or defects caused during the handling of the profiles. o Elimination of superficial stains. o 1.5 Kilos of consumption of stainless shot per ton of anodized profile. o Depending on the temperature of the bath and the level of concentration of caustic soda used in the process, the time of the alkaline...

General Characteristics of the shotblasting equipment for aluminum profiles. • Proper distribution of the turbines achieving an excellent shotblasting coverage. Possibility of decreasing or increasing the speed of impact of the abrasive in a way that allows to adjust conveniently the roughness obtained in the process. Automatic opening and closing of the shot valves to avoid the unnecessary wear of the equipment. Intermediate cyclone to perform a correct separation of abrasive/dust avoiding that good abrasive is withdrawn from the equipment unnecessarily. Internal covering of working chamber...
