Hiperbaric, Burgos, Spain, has launched a new Hot Isostatic
Pressing (HIP) system designed for use in the metal Additive Manufacturing
industry. The move was announced at the company’s twentieth anniversary event,
which coincided with the inauguration of its recently expanded
Hiperbaric was launched in 1999 with the development of its
first High Pressure Processing (HPP) equipment, a technology which employs high
isostatic pressures (up to 6000 bar) to extend the shelf life of food and guarantee
food safety. Its new business line will focus specifically on the production of
HIP systems for the post-processing of metal parts.
At the anniversary event, attended by over 500 people,
Andrés Hernando, Hiperbaric CEO, stated, “This new technology has been
developed thanks to an investment of over €4 million and a tremendous
engineering effort over more than three years.”
HIPing has multiple applications, among which are the
elimination of defects in parts produced by AM, the sintering of Powder
Metallurgy parts, and the densification of castings. The new equipment
developed by Hiperbaric has a maximum operating pressure of 2,050 bar and an
oven with molybdenum resistors that allows it to reach 1,400°C. Its hot
zone has a diameter of 380 mm and a length greater than 1,000 mm, enough to
house the build volumes of most AM systems on the market.
The HIP pressure vessel incorporates proven wire winding
technology that is said to provide a vastly improved fatigue life and maximum
safety, thanks to its ‘leak before burst’ failure mode. In addition, thanks
to this design, Hiperbaric states that it has been possible to implement a
rapid cooling system that significantly shortens the cooling stage,
guaranteeing the metallurgical properties of the parts and improving the
productivity of the equipment.
dedication has allowed the company to become the world benchmark on HPP for the
food industry. Today, its target is to become the leader of high pressure
technology, regardless the industry of application,” added Hernando.
