PTC Industries Limited has taken a significant step into the global space launch ecosystem after its wholly owned subsidiary, Aerolloy Technologies Limited, received a prestigious development and supply order from Blue Origin. The order covers the manufacture of large, high-precision Superalloy investment castings for the BE-4 rocket engines that power the first stage of Blue Origin’s New Glenn heavy-lift launch vehicle.
This development follows an extensive technical, qualification, and regulatory approval process, including compliance with stringent international export control frameworks. Such clearances highlight the mission-critical nature of the BE-4 propulsion system and underline the high level of trust placed in Aerolloy’s manufacturing capabilities.
Under the programme, Aerolloy will produce large nickel-based Superalloy housings and manifolds used in the liquid oxygen high-pressure and low-pressure systems of the BE-4 engine. These components are designed to operate under extreme thermal, chemical, and pressure conditions, where even microscopic defects can compromise engine performance and safety. Manufacturing such parts requires exceptional dimensional accuracy, complex internal geometries, and flawless metallurgical integrity, capabilities that only a limited number of foundries worldwide currently possess.
A major technological differentiator enabling this order is Aerolloy’s recently commissioned Vacuum Induction Melting furnace. The facility allows controlled melting and processing of large Superalloy heats under vacuum conditions, creating the metallurgical foundation required for large, high-integrity investment castings used in advanced rocket propulsion systems. This infrastructure positions Aerolloy among a select global group capable of supporting orbital-class engine programmes.
For Blue Origin’s New Glenn programme, the partnership strengthens supply-chain resilience and supports long-term scalability as the vehicle moves toward a regular launch cadence. New Glenn, a reusable heavy-lift orbital launcher, uses seven BE-4 engines on its first stage, each delivering roughly 550,000 lbf of thrust. The Superalloy LOX housings and manifolds supplied by Aerolloy are central to engine reliability, performance, and reusability, making them some of the most technically demanding elements of the propulsion system.
From Aerolloy’s and PTC Industries’ perspective, the order marks a strategic expansion beyond traditional aerospace and defence applications into launch-vehicle engine systems. It validates Aerolloy as a qualified supplier for orbital-class propulsion hardware and reinforces PTC Industries’ vertically integrated manufacturing model, spanning alloy production, vacuum melting, near-net-shape casting, and advanced downstream processing. This integration enhances competitiveness in globally scaled and long-duration space programmes.
