Metal Surface Preparation

The surface of the metal should be prepared for increasing the rubber bonding performance and / or providing the desired corrosion resistance. The following processes are applied within our structure:

1. Pre-greasing (metal and aluminum parts)
2. Sand blasting (metal and aluminum parts)
3. De-greasing line (with PLC automation for metal and vulcanized parts)
4. Zinc phosphating (with PLC automation for metal and vulcanized parts)
5. Alkali zinc coating (with Cr+3 passivation for metal and vulcanized parts)
6. Greasing (for finished products).

The “bonding application” is carried out with the various following methods:

1. Spraying
2. Automatic robot spraying
3. Tumble spraying
