Castool Tooling Systems Expands Capabilities with Nitrex Turnkey Nitrocarburizing System

In a significant development, Nitrex, the global leader in the surface treatment industry, has announced a groundbreaking expansion by Castool Tooling Systems, a division of Exco Technologies and a renowned tooling provider for extrusion and die-casting companies. Castool Tooling Systems has bolstered its in-house capabilities with the addition of a cutting-edge Nitrex turnkey nitrocarburizing system, marking a remarkable stride in the world of heat-treating processes.

This expansion project, which unfolded in collaboration with several furnace OEM suppliers, has transformed Castool's facility in New Market, Canada. The facility has a state-of-the-art large-capacity furnace that promises to revolutionize its heat-treating processes.

Nitrex, a pioneer in the field for over 35 years, has been a trusted name in delivering metal service treatment solutions. Their expertise extends to turnkey heat-treat systems featuring proprietary high-end instrumentation and failsafe digital controls. The centerpiece of this endeavor is the model NX-1625 pit-type nitrocarburizing furnace, designed to handle substantial workloads of up to 6,000 kg (13,200 lb.) with dimensions of 1550 mm (61”) in diameter and 2500 mm (98.5”) in height.

The turnkey solution includes cutting-edge Nitreg-C controlled nitrocarburizing technology and incorporates ONC post-oxidation processes. These advanced technologies come with proven recipes tailored to treat shot sleeves made of H13 tool steel effectively. The result is enhanced strength and longevity of the shot sleeves, making them exceptionally reliable in high-temperature and corrosive environments. Moreover, the process eliminates the need for component post-finishing, as treated parts retain their dimensional stability.

This remarkable expansion by Castool Tooling Systems signifies a significant leap forward in the heat-treating industry, powered by Nitrex's cutting-edge technology and Castool's commitment to excellence. The newly equipped facility is poised to offer enhanced services to extrusion and die-casting companies, further solidifying their position as leaders in the industry.
