Paulo will add hot isostatic pressing to its thermal-processing services with the acquisition of a hot isostatic press (HIP) from Quintus Technologies. The press is equipped with Quintus’ proprietary uniform rapid cooling (URC), a feature that improves material properties in additive manufacturing and investment casting. The HIP will be installed in Paulo’s recently expanded Cleveland Division in Willoughby, Ohio, which provides specialized brazing and vacuum heat treatment.
The press has a work zone of 26 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 maximum pressure of 30,000 psi (2,070 bar).
The 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. Heating and cooling the workload only once, in a single cycle, enhances efficiency and reduces per-unit processing costs. Paulo and Quintus Technologies have also entered into a marketing agreement that reflects the commitment of both companies to work closely together to spread the use of the HPHT process.
