Paulo Heat Treating, Willoughby, Ohio, will add hot isostatic pressing to its thermal processing services with the acquisition of a hot isostatic press from Quintus Technologies. The press, model QIH 122 M URC, is equipped with Quintus’ proprietary uniform rapid cooling (URC), a feature that improves material properties in additive manufacturing and investment casting.


“We see the market for HIP expanding, with a large part attributed to additive manufacturing,” says Scott Herzing, Paulo Vice President Engineering. “We have the leading material knowledge and process expertise to help our customers in this area. The ability to combine HIP and heat treatment will allow us to offer one-stop-shop thermal processing solutions, with faster turnaround times.”


The HIP will be installed in Paulo’s recently expanded Cleveland Division, which provides specialized brazing and precise vacuum heat treatment. The plant’s AS9100 quality management system and Nadcap accreditation make it especially well-suited to serve the needs of the aerospace and power generation industries.


Configured as a Quintus Modularized Solution, a space- and energy-saving profile that simplifies building and civil work and reduces infrastructure investment, the press features a work zone of 26.0 inches (660 mm) in diameter and 68.9 inches (1,750 mm) in height. It operates at a maximum temperature of 2552°F (1400°C) and a maximum pressure of 30,000 psi (2070 bar).


The press’s unique URC feature streamlines the steps involved in material densification by combining heat treatment and cooling in a single process, known as High-Pressure Heat Treatment (HPHT). The design enables all processed components to cool uniformly, minimizing thermal distortion and non-uniform grain growth, improving their performance. Heating and cooling the workload only once, in a single cycle, enhance efficiency and dramatically reduces per-unit processing costs. In addition to turnkey delivery, the Paulo order includes an extra furnace base, extended warranty, and a five-year Quintus Care agreement.
