A (HIP) from Quintus Technologies is at the heart of Wallwork Group’s new HIP Centre which is set to open in Bury, North Manchester, England, in September 2023. The press is the model QIH 173L M URC, equipped with Quintus’ proprietary uniform rapid cooling (URC), a feature that delivers the high material uniformity required of parts designed for mission-critical applications, while enabling increased productivity with optimal temperature control.

Operating at a maximum temperature of 1250°C (2282°F) and pressure of 207 MPa (30,000 psi), the technologically advanced press has a work zone measuring 800 mm (34.6 inches) in diameter and 2,550 mm (100.4 inches) high, and a capacity of over 7,000 kg (15,432 lbs) per cycle.

Wallwork, the UK’s premier independent heat treatment, vacuum brazing, and advanced ultra-hard coatings company, is expanding its thermal processing. The investment is driven by the upsurge in additive manufacturing, where Hot Isostatic Pressing has proven to play a pivotal role in producing components with improved material fatigue properties, ductility, structural integrity, and fracture toughness.

“HIP is extremely efficient at removing the porosity from AM parts made from metal powders. This densification process is often the only way for AM builds to fulfill their safety-critical potential,” said David Loughlin, HIP Business Manager at Wallwork.

The QIH 173L press will also serve Wallwork customers with applications requiring the densification of castings, forgings, and subtractive-engineered components. HIP is well suited to parts with complex geometries, which can be processed to near-net shape, saving cost by reducing the need for further machining.

Wallwork is complementing its press investment with the Quintus Care Program, a rigorous agreement that ensures flawless press operation and equipment maintenance. The agreement provides for prioritized technical support and high availability of spare and wear parts. It also includes application support, regular press inspections, and training and recertification of Wallwork personnel to maintain and elevate their skills.

Wallwork’s £10 million investment to prepare and equip the Bury HIP Centre is part of a £20 million, five-year commitment to bolster its position as a single-source provider of secondary processes for component manufacturers, from multiple facilities linked by an internal transport network. The company’s Bury location also houses the UK’s largest single-site heat treating facility with an aerospace scope – covering nine Nadcap check sheets. Following the Quintus press installation, additional certifications and approvals are anticipated, according to Simeon Collins, Director of Wallwork.

“As the industry leader in high pressure for over 70 years, we have seen the need for Hot Isostatic Pressing increase steadily,” said Jan Söderström, CEO of Quintus Technologies. “Wallwork has a solid understanding of the value of this process, and we share a similar focus on customer-driven problem-solving and long-term supplier partnerships. We are very pleased to see the establishment of their HIP Centre with our technology at its core.”
