Simply put, Hot isostatic pressing (HIP) enables the production of complex parts using AM technologies that would be difficult to produce using conventional methods. By removing pores and internal defects in metal and ceramic parts, such type of system enables to improve properties such as toughness and fatigue life. Its main advantages are, the quality of parts that are produced with metal powders can be compared to those produced with conventional techniques.
So far, Quintus Technologies HIP has been used by Paulo and FIT Additive Manufacturing Group. Even though we do not know the main difference between the former system and the new one, the company explained that the new system, named QIH 60 M URC®, combines heat treatment and cooling in a single process known as High Pressure Heat Treatment (HPHT), for faster throughput, higher work piece quality, and capital investment, logistics, and energy savings.
Equipped with digital controls for precise heating and cooling performance, the new press has been designed to integrate with Industry 4.0 and factory-of-the-future connectivity. The QIH 60 operates at a maximum temperature of 1400°C (2552°F) and pressure of 30,000 psi (2,070 bar) when using the molybdenum furnace. Graphite furnace options are also available for temperatures up to 2000°C (3632°F). The working dimensions of the vessel are 410 mm (16.14”) in diameter and 1000 mm (39.37”) in height, with a capacity of 600 kg (1,322 lbs) per load, allowing loading of full build plates from the majority of printers.
“HPHT introduces multiple efficiencies and dramatically lowers per-unit processing costs,” comments Jan Söderström, CEO, Quintus Technologies. “We are very pleased with the role this new, state-of-the-art HIP can play in moving additive manufacturing forward into robust, lean production.”
