Metallic fibre masterbatch to enhance electromagnetic shielding

Kay Pee Dies is also a pioneer in installing the latest German automatic die grind ing/polishing and finishing machines, for improved quality and uniformity in dies, resulting in higher productivity and bet ter wire quality and surface. The Kay Pee group’s product ranges include tungsten carbide dies, wear parts and cone rings; quality lubricants and surface coating compounds; and die shop machines and consumables. It also Delta Tecnic’s new metallic fibre master batch, composed of 75 per cent metallic fibres and 25 per cent polymer, is dosed directly in the injection or compounding processes. This mixture allows customers to produce compounds for conductive plastic parts with the freedom of colour and allowing the substitution of metal parts for plastic parts, while maintain ing the conductive and electromagnetic shielding properties. The metallic fibres within the plastic ma trix help to create a “Faraday cage”, which acts as a barrier to electromagnetic inter ference generated by magnetic fields. One of the main applications of this technology is electromagnetic shielding in automotive parts. With the increas ing adoption of electric vehicles, where high-voltage cables generate electro magnetic fields that can interfere with other electronic systems, some plastic parts now need efficient shielding. There are also applications in the production of

Founded in 1968 with a modest beginning, while pioneering the manufacture of tungsten carbide dies in India, Kay Pee Dies is now a major company serving the wire drawing, bar drawing, fastener and other industries. Since 2008, Kay Pee Dies has been the exclusive India and SAARC countries agent/distributor of wire drawing lubri cants and surface coating compounds from M/S Pan Chemicals SpA, Italy. Efficiency and electromagnetic pro- tection are becoming increasingly important in the plastics industry. Delta Tecnic, a manufacturer of masterbatches for the plastics and cable industry, has launched its own line of metallic fibre masterbatches, with technology designed to improve conductivity and offer advanced solutions in electromagnetic shielding (EMI shielding) – a key challenge in sectors such as automotive, electronics and telecommunications. Traditionally, the conductivity of plastics has been based on carbon technology, which limits colour options and restricts conductivity and electromagnetic shielding levels due to the maximum absorption capacity of polymers. Delta Tecnic’s alternative incorporates metallic fibres into plastic composites, allowing the creation of conductive plastics that not only offer higher electromagnetic efficiency, but can also be manufactured in a wide range of colours.

offers consultancy for die management, to optimise die cost per ton of product. The company exports 40 per cent of its products to SAARC countries, the Middle East and countries in Africa. It aims to increase this export share to 50 per cent by expanding into newer and developed markets. Kay Pee Dies India Pvt Ltd www.kaypeedies.com “Thanks to our constant commitment to innovation, Delta Tecnic has succeeded in developing a technology that im proves the efficiency and electromag netic properties of plastics, and also fa cilitates the production of lighter, more colourful and better performing parts,” said Manuel Miret, area manager and new product developer. “Metallic fibres offer manufacturers a powerful tool to adapt their products to the demands of a market that demands more efficient, safer and more economical solutions.” Delta Tecnic SA www.deltatecnic.com conductive PVC flooring, used in environ ments where it is essential to dissipate electrostatic energy, such as hospitals.
