Precision lost-wax casting from 10g to 50kg in stainless, carbon, and alloy steels. ±0.1mm tolerance, near-net shape, ISO 9001:2015 certified suppliers.
Investment casting — also called lost-wax casting — is the process of choice when your part demands intricate geometry, tight tolerances, or premium surface finish that machining alone can’t deliver economically.
Magnus partners with 60+ ISO 9001:2015 certified Indian foundries. We’ve shipped over 8 million precision-cast components to OEMs in automotive, aerospace, medical, and industrial machinery — from 10-gram surgical parts to 50-kilogram pump bodies.
For complex shapes that would require multiple machining setups, investment casting delivers near-net-shape parts with 60-80% less machining.
