In a landmark development for India’s aerospace and defense manufacturing sector, PTC Industries Ltd., through its wholly owned subsidiary Aerolloy Technologies, has commissioned the country’s first private Vacuum Induction Melting (VIM) facility dedicated to producing high-performance superalloys. This state-of-the-art installation represents a major leap forward in India’s quest for self-reliance in critical materials and positions Aerolloy among a select group of global manufacturers capable of producing aerospace-grade titanium and nickel-based alloys.
A Strategic Leap in Metallurgical Capability
The newly commissioned VIM facility is designed to produce superalloys with exceptional purity, homogeneity, and mechanical strength—qualities essential for aerospace, defense, and high-performance industrial applications. Operating under vacuum conditions, the VIM process eliminates gaseous impurities and prevents oxidation during melting, resulting in defect-free ingots with superior metallurgical integrity.
This facility complements Aerolloy’s earlier milestone: the commissioning of India’s first private Vacuum Arc Remelting (VAR) furnace, which enabled the domestic production of aerospace-grade titanium alloy ingots2. Together, the VIM and VAR units form a vertically integrated ecosystem capable of producing ingots, billets, bars, plates, and sheets for jet engines, airframes, and other critical components.
Technology That Rivals Global Standards
The VIM furnace, engineered in Germany and installed at Aerolloy’s advanced manufacturing campus in Lucknow, boasts an annual melting capacity of 1,500 metric tonnes. It can produce ingots up to 1,000 mm in diameter and weighing up to 10 metric tonnes. This scale and precision place Aerolloy in the same league as elite manufacturers in the United States, Russia, China, France, and the United Kingdom.
Jim Collins, Chief Technology Officer of PTC Industries, emphasized the strategic importance of the facility: “With the commissioning of this VIM unit, we now match global standards in the production of aerospace-grade superalloys. This is not just a technological achievement—it’s a statement of India’s capability to lead in advanced manufacturing.”
A Boost to India’s Self-Reliance and Global Competitiveness
For decades, India has relied heavily on imports to meet its demand for aerospace-grade titanium and nickel alloys. These materials are vital for defense aviation, space exploration, and industrial engineering. The commissioning of the VIM facility decisively addresses this dependency, aligning with the government’s “Make in India” and “Aatmanirbhar Bharat” initiatives.
Sachin Agarwal, Chairman and Managing Director of PTC Industries, remarked, “This achievement is a turning point—not just for Aerolloy and PTC Industries, but for India’s entire aerospace ecosystem. We’ve demonstrated that Indian companies can lead in precision metallurgy and supply chain resilience.”
The facility is part of a broader expansion within the Uttar Pradesh Defence Industrial Corridor, where PTC Industries is developing a fully integrated titanium and superalloy mill. This strategic location offers proximity to defense clients and access to skilled talent, further strengthening India’s position in the global aerospace supply chain3.
Implications for Global Aerospace and Defense Markets
The commissioning of the VIM facility opens new avenues for export and international collaboration. With capabilities that meet or exceed global benchmarks, Aerolloy is poised to become a preferred supplier for aerospace OEMs and defense contractors worldwide.
Industry analysts view this development as a game-changer. By offering domestically produced, high-quality superalloys, India can reduce lead times, lower costs, and enhance strategic autonomy in defense procurement.
What’s Next for Aerolloy?
Aerolloy Technologies plans to expand its product portfolio to include nickel-based superalloys, which are essential for turbine blades and other high-temperature applications. The company is also exploring partnerships with global aerospace firms to co-develop next-generation materials.
With the VIM and VAR facilities now operational, Aerolloy is well-positioned to lead India’s transformation into a global hub for advanced metallurgical manufacturing.
