ACME attended the 5th HT&HIP Conference to share the latest technological breakthroughs in ultra-large hot isostatic pressing equipment

On April 8, 2026, the 5th Conference on Advanced Manufacturing in CommercialHeat Treatmentand Hot Isostatic Pressing, organized by Xingang Culture, officially opened in Wuxi. The three-day event brought together more than 500 experts, scholars, and corporate representatives from across the global heat treatment industry’s supply chain to engage in in-depth discussions on cutting-edge technologies, development trends, and innovative applications.

During the Hot Isostatic Pressing (HIP) special forum, Hu Gaojian, Deputy General Manager of ACME’s Carbon-Ceramic Technology Division, delivered a keynote presentation titled “Key Technological Breakthroughs in HIP Equipment: Ultra-High Temperature and Pressure Design and Safety Control,” sharing the company’s latest technological achievements in ultra-large, high-end HIP equipment.

Hot isostatic pressing (HIP) is an advanced processing technique that applies isotropic static pressure to materials in a sealed high-temperature, high-pressure environment using an inert gas as the pressure-transmitting medium, thereby achieving densification and eliminating internal defects. Its operating principle involves using high temperatures to activate material diffusion and creep, resulting in high density, uniform microstructure, and superior properties, which significantly enhance mechanical strength, wear resistance, and corrosion resistance. After HIP treatment, the fatigue life of materials increases by 10 to 100 times, with density approaching the theoretical value (over 99.8%). Internal pores and microcracks are almost completely eliminated, meeting the demands of “extreme operating conditions” in high-end manufacturing sectors such as aerospace and new energy, where material reliability is of the utmost importance. This technology is widely applied in aerospace, nuclear energy, petrochemicals, high-end medical implants, and additive manufacturing. It serves as a core process for the fabrication of critical components made from high-performance titanium alloys, superalloys, and refractory metals, such as aerospace turbine blades, nuclear reactor components, and silicon nitride ceramic balls for new energy vehicles.

In his report, Hu Gaojian outlined the company’s technical expertise and innovative advancements in this field. Drawing on more than two decades of research, development, and practical experience, ACME has established comprehensive capabilities in the development of ultra-large-scale, ultra-high-temperature, ultra-high-pressure, intelligent, and customized solutions. Currently, the hot isostatic pressing (HIP) equipment developed by the company features a working chamber diameter of up to 2,500 mm, with a maximum temperature of 2,000°C and a maximum pressure of 200 MPa; certain models can even reach a working pressure of 300 MPa. Additionally, the integration of multiple proprietary technologies in equipment design and manufacturing has comprehensively enhanced the stability, reliability, and process sophistication of the equipment.
