Promoted by Ashok Jaipuria and his associates, and Cosmo Films, Cosmo Ferrites (CFL) has been manufacturing soft ferrites since 1988 at its plant in Solan, in Himachal Pradesh. It was set up in technical collaboration with Veb Elektro-Consult, Germany. The types of ferrite core manufactured by CFL include U and E cores (used in power transformers for SMPS, telecommunication, computers and lighting systems) and yoke rings (used in deflection yokes of TVs). CFL classifies the U and E cores as nitrogen cores, and yoke rings as oxygen cores, according to the atmosphere prevalent at the sintering stage. Though the cost of producing the latter is lower, the value-addition is greater in the former. Owing to a buy-back agreement with the collaborator, CFL's performance in the first year, 1988-89, was noteworthy. But since the technology transferred was poor, the company had various manufacturing problems. The tie-up was subsequently called off in 1989.
