Hot isostatic pressing (HIP) is a process used to eliminate internal voids and defects such as porosity in castings, additive-manufactured (AM) parts and MIM parts to achieve a 100%-dense material.

Quintus Technologies received an order for a hot isostatic press (HIP) from HT-MX, a heat-treatment specialist based in Chihuahua, Mexico. The press includes Quintus’ proprietary uniform rapid cooling (URC) feature, which combines HIP and heat treatment in a single process. The HIP has a hot zone measuring 14.8 inches (375 mm) in diameter and 47.2 inches (1,200 mm) in height. It operates at a temperature of 2550°F (1400°C) and a pressure of up to 2,070 bar (30,000 psi).

Stack Metallurgical Group, after installing a hot isostatic press (HIP) earlier this year, is redoubling its commitment to the technology with the addition of a second HIP from Quintus Technologies. The unit has a work zone of 26 inches (660 mm) in diameter and 68.9 inches (1,750 mm) in height. It follows the installation in January of a high-capacity Mega-HIP, which has a work zone of 63 inches (1,600 mm) in diameter and 102 inches (2,591 mm) in height. The new press, which operates at a maximum temperature of 2552°F (1400°C) and a maximum pressure of 30,000 psi (2,070 bar), will be installed at Stack’s recently completed facility in Albany, Ore. Both systems are equipped with the Quintus proprietary uniform rapid cooling (URC) feature, which combines HIP and heat treatment in a single process.

Accurate Brazing, based on market feedback, added a second hot isostatic press (HIP) from Quintus Technologies. Both presses are equipped with Quintus’ proprietary uniform rapid cooling (URC) technology, which combines HIP and heat treatment in a single process, and will be installed at Accurate Brazing’s newest facility in Greenville, S.C. The process, called high-pressure heat treatment (HPHT), streamlines the steps involved in material densification and heat treatment. It also enables all processed components to cool uniformly, resulting in minimal thermal distortion and non-uniform grain growth.

Alfa Romeo Racing, operated by Sauber Motorsport AG, selected Quintus Technologies as its hot isostatic pressing (HIP) partner. The Formula One team invested in a press with proprietary URQ technology, which allows heat treatment and cooling to be combined in a single process, known as high-pressure heat treatment (HPHT). HPHT and HIP are used for the consolidation and densification of metal, producing a maximum theoretical density, ductility and fatigue resistance in high-performance materials. This makes it ideal for ultrahigh-performance automotive applications.

Accurate Brazing, a full-service provider of specialized heat-treating solutions, will add hot isostatic pressing to its thermal-processing capabilities with the installation of a hot isostatic press (HIP) from Quintus Technologies. The press is equipped with Quintus’ proprietary uniform rapid cooling (URC), a feature that combines HIP and heat treatment in a single process and improves material properties of parts designed for mission-critical applications. It will be installed in Accurate Brazing’s recently opened facility in Greenville, S.C.

Quintus Technologies will deliver a hot isostatic press (HIP) with uniform rapid quenching (URQ) to the FIT Additive Manufacturing Group. Coming online in September 2019 at FIT’s main facility in Lupburg, Germany, the HIP will enable the additive-manufacturing (AM) specialist to boost productivity while meeting the heightened industrial requirements for 3D-printed metal parts. Operating at a temperature of 2552°F (1400°C) and pressure of 30,000 psi (2,070 bar), the press has a capacity of 264 pounds (120 kg) per load in a work zone that measures 10.6 inches (270 mm) in diameter and 19.7 inches (500 mm) in height.

Many factors come into play during the vacuum sintering process, from the size and materials used in the furnace hot zone to whether debinding and sintering processes are combined in a single unit.

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.

Portland, Ore.-based Stack Metallurgical Group is expanding its existing heat-treating and metal-processing portfolio with the addition of a Mega-HIP from Quintus Technologies. The hot isostatic press (HIP) is equipped with Quintus Technologies’ proprietary uniform rapid cooling and includes a large-capacity work zone of 63 inches in diameter and 102 inches in height, allowing densification of large batches at 29,000 psi (2,000 bar). The HIP has a maximum operating temperature of 2280°F (1250°C).
