The new year has finally begun: following the first few days of physiological recuperation from the Christmas holidays we are now operating in 2019 at full capacity.
In the same way that 2018 was the year marked by the celebrations of our 30 year anniversary in business, 2019 begins with the launch of new systems that project us towards the future.
The arrival of HIP (hot isostatic pressing) is now imminent, but what is different compared to the other numerous systems promoted by TAG?
Those of you who know us well, are perfectly aware that the renewal and implementation of our fleet of machinery is a continuous process, so how come in the last few months we have noted all this curiosity for the arrival of this new system?
We will try to explain the phenomenon in simple terms.
HIP: WHY IS IT SO SPECIAL?
The HIP system allows you to perform a “heat treatment” different from the traditional versions that you would usually think of: even the name – hot isostatic pressing – suggests the use of high temperature and isostatic pressure.
Their combined effects serve to densify and eliminate or reduce defects of a various nature in relation to the material, and improve the mechanical properties of the processed part.
This type of process is increasingly diffused in applications involving – among others – the aeronautical, energy and biomedical sectors.
The additive manufacturing sector deserves a separate mention, where the requests for the application of the HIP process continue to increase.
Powder technology is literally revolutionising the global production panorama, and required a series of ad hoc processes and treatments that high-tech enterprises are trying to cope with as efficiently as possible.
Other hipping treatment applications include the reconstruction of profiles and the sintering of metal powders in solid parts: in this case the materials, in the form of calibrated granules, are encapsulated in special containers and, with the application of specific temperatures and pressures, are transformed into completely dense solid parts with almost final geometries.
THE CHARACTERISTICS OF THE HIP PLANT IN TAG
Two plant systems will soon be installed at the Cremella facility: the first will soon arrive and is a small furnace that will be dedicated to the exceptionally important research and development activities. The thermal chamber is cylindrical, made of graphite, has a diameter of 77 mm x 150 mm in height and reaches a temperature of 2000°C and a pressure of 200 MPa; the process gas is Argon and the maximum load capacity is 10 Kg.
The arrival of the large sized plant system, which will be totally dedicated to production, is expected by the spring: the diameter of the chamber is once again cylindrical, but this time made of molybdenum, it measures 1000 mm by 1500 mm in height, reaches a temperature of 1400°C and a pressure of 175 MPa; the process gas is again Argon and the maximum load capacity is 10 Ton.
