Nitrex secures VPA coating furnaces supply deal from a jet engine manufacturer

A leading manufacturer of jet engines, known for its dedication to enhancing manufacturing capabilities, has announced plans to integrate two state-of-the-art Vapor Phase Aluminizing (VPA) coating furnaces from G-M Enterprises, a Nitrex company, in the first half of 2024. This strategic move signifies a significant advancement in aerospace manufacturing and underscores the enduring partnership between the two entities. Over time, the customer has consistently relied on Nitrex vacuum furnaces across multiple locations.

The newly acquired VPA furnaces are designed for high capacity and low maintenance, featuring automated retorts with moving bases and a fixed heat chamber to optimise operational efficiency. With each retort securely sealed to the moving bases, the furnaces can concurrently handle two loads, each containing three coating cans. This setup enables a streamlined process, with two cycles running consecutively to complete the treatment within approximately 24 hours.

The furnaces have automation capabilities, allowing unattended start-ups and operators to focus on preparing loads for the second system. This concurrent operation setup enhances productivity significantly.

The National Sales Manager Robert Huckins emphasises, “Our VPA furnaces ensure seamless operations, providing our customers with a competitive edge in production capacity. This is crucial in meeting escalating demand while delivering high-performance, longer-lasting blades and vanes vital for high-temperature fired engines.”

The distinctive feature of the Nitrex VPA design lies in its raised fixed heat chamber, which effectively shields operators and the furnace room from potential heat exposure. This innovative design eliminates the necessity for cumbersome protective heat suits, ensuring operator safety. The hot retort remains securely enclosed within the insulated furnace, prioritising the well-being of operators.

Moreover, this safety measure ensures that the load base and retort/coating load remain confined within the SAR/VPA furnace housing until the retort temperature decreases below 150°C (300°F). This meticulous focus on safety underscores the dedication to operational excellence throughout the process.

This strategic investment demonstrates the manufacturer's commitment to remaining at the forefront of technological advancements. It reinforces a longstanding partnership, reflecting the mutual trust established through multiple acquisitions of various vacuum furnaces. As the aerospace industry continues to evolve, these Nitrex furnaces are positioned to play a crucial role in enhancing jet engine performance to unprecedented levels.
