HHV DEVELOPS ENVIRONMENTAL FRIENDLY PROCESS TO REPLACE PLATING ON PLASTICS/METALS



Pioneering new ‘Made in India’ technology for industrial applications that will drastically reduce carbon footprint

Mumbai, August 28, 2017: Hind High Vacuum Co. Pvt. Ltd. (HHV), a vacuum science and technology company,  with major clients like HAL, ISRO, BARC, Titan etc, announced  that is has pioneered and developed a new path breaking environment friendly process to replace plating on plastics/metals. This unique ‘Made in India’ technology drastically reduces carbon footprint and was entirely developed by HHV’s dedicated team of R&D professionals out of its facility in Bengaluru.

With the introduction of Electro Magnetic Interference (EMI) shielding service for a project on neonatal heart rate monitor, HHV has brought the first ever consumer use of EMI shielding coating in the country by replacing the plating process by coating using Dual Magnetron Sputtering technology. EMI shielding done with dual magnetron sputtering happens to coat metals like Copper and Nickel even on non conducting plastic substrates eliminating the necessity of plating and its associated use of toxic chemicals

Conventionally Plating is the most commonly used metal coating technique in our country, but not many are aware of its dark side of pollution. The hazardous wastes generated during the process affects the natural resources by way of polluting the ground water, fertility of soil and increase toxicity of air which in most cases is irreversible. Plating is a process by which a metal coating is done with or without application of electric current by immersing the object in an aqueous solution.

Currently plating is a widely used technique in automobile industry, decorative coatings and Printed Circuit Boards. Due to frequent replenishment of the aqueous solution for higher efficiency, waste management of the reagents becomes important. If the effluents are not meticulously neutralized and treated properly it leads to environmental pollution.

“India is already on the oath on clean energy and has further set higher targets on clean energy growth. Even under new tax regime, 18% tax is being proposed to be levied on electric cars vis a vis 28% tax on conventional cars. India also aims to be producing 40% of its installed electricity capacity by 2030 on non-fossil fuels” said Prasanth Sakhamuri, Managing Director of HHV. “Under such an environmentally conscious government leadership, HHV takes the leap by leading the industry to reduce carbon footprint. We have always looked at identifying new technologies with reduced carbon emission to fulfil our industrial objectives. One such initiative was the development of a process of coating using Dual Magnetron Sputtering technology as an effective alternative to plating on metal or plastic substrates”.

With 52 years of unparalleled expertise in vacuum technologies, the R&D team at HHV has self-developed many sputtering deposition equipments with process control which work on above technology.HHV has demonstrated skills of Sputtering by replacing black Chrome coating done by Electroplating which was used for solar water heating through equivalent solar absorber coatings by sputtering and even sold the systems. ISRO has also vetted on the quality of sputtering as space qualified for a recent development project done on Thin Film Metallization on Alumina substrates. Similarly protective Aluminium coatings on jewellery stones also have been undertaken. Apart from these, numerous small scale industries have sought the help of HHV’s service for decorative coatings on cutlery, imitation jewellery, watch straps and cases.

“HHV has demonstrated thought leadership in India by introducing cleaner technology for other companies to follow. Already, European countries observe a strict ban on electroplating and sooner or later India will have to comply with strict regulations on environmental protection. We believe that our innovation will lay path for companies across to follow and help us create a safer environment”, added Prasanth Sakhamuri.
