Involute Engg Industries Private Limited has been converted to present corporate status from previous Involute Engineers And Industries. We have been at the forefront of manufacturing electro-mechanical and electro-pneumatic equipment for railway transportation since 1982. With a commitment to indigenous development and import substitution, we have significantly contributed to the railway sector. Notably, our indigenously developed critical spares and sub-assemblies for the N-32 Tap Changer have become vital in A/C electric locomotives. Over the years, Involute has established itself as a trusted supplier to major railway component manufacturers, including Bombardier and Adtranz, catering to the needs of electric loco sheds across India.
