Russian steel pipe maker United Metallurgical Company OMK purchased for its plant in Chusovoy in Perm Territory in Russia, which produces springs for Russian and foreign brands of trucks, an abrasive blast chamber for cleaning cassettes, a specialized container for transporting springs and leaf springs on a painting line conveyor. This will guarantee a consistently high quality of the color of the spring sheets. The volume of investments amounted to about 1.5 million rubles.About 500 cassettes are used on the conveyor of the spring production line. The general requirements for the technological process of priming by cathodic deposition on the painting line require regular cleaning of the contact surfaces of the product to be painted and the tooling. This creates optimal conditions for applying the necessary layer of soil, which ensures the corrosion resistance of the spring.After repeated use, the cassettes are covered with a layer of paint, which can lead to incorrect positioning of the leaf springs and deterioration in the quality of the painting. Previously, the paint was removed with a hand tool. At the same time, the complexity did not allow cleaning the cassettes regularly. Now the cassettes are placed in a special chamber, the operator is working in protective gloves, being outside the chamber. Quarterly cleaning of all cassettes with an abrasive-air mixture will minimize the possibility of an unpainted defect and repaint the spring leaves to eliminate it, which increases the overall efficiency of the production process.
