Title of Product / Design / Equipment:

    Sputter Etching of brass valves for bonding to rubber

IPR Status Patent/ Copyright/ Trademark
secured in Indian/Abroad IPR Details:



    Etched surface of brass valves can be used for bonding to rubber tubes

Salient Technical Features including
Competing Features:

  • *The hazardous chemicals used in chemical cleaning cum etching may release hydrogen onto the surface of the metal and causes embrittlement of the same. Sometimes improper removal of dust constituents from chemical etching takes place leaving a smut on the metal surface. All these are avoided by sputtering process as it is a eco- friendly process; in addition a good substitute process for etching.
