The HIP process subjects a component to both elevated temperature and isostatic gas pressure within a high-pressure containment vessel, unlike the cold isostatic pressing (CIP), where the component is maintained at room temperature. [2] The pressurizing gas most widely used is argon. An inert gas is used so that the material does not chemically ...
The Alcoa 50,000 ton forging press is a heavy press operated at Howmet Aerospace's Cleveland Operations. It was built as part of the Heavy Press Program by the United States Air Force . It was manufactured by Mesta Machinery of West Homestead, Pennsylvania , and began operation on May 5, 1955.
The general press tool construction will have the following elements: Shank: It is used as a part for installing the Press tool die in the slide of the press machine with proper alignment. Top Plate: It is used to hold top half of the press tool with press slide. It is also called Bolster Plate.
Hot pressing is a high-pressure, low-strain-rate powder metallurgy process for forming of a powder or powder compact at a temperature high enough to induce sintering and creep processes. [1] This is achieved by the simultaneous application of heat and pressure. Hot pressing is mainly used to fabricate hard and brittle materials.
Isostatic presses can be either high speed, high output type of automatic presses for such parts as ceramic insulators for spark plugs or sand blast nozzles, or slower operating "wet bag" presses that are much more manual in operation but suitable particularly for large machinable blanks or blanks that will be cut or otherwise formed in ...

Powder forging: A "preform" made by the conventional "press and sinter" method is heated and then hot forged to full density, resulting in practically as-wrought properties. [citation needed] Hot isostatic pressing (HIP): Here the powder, normally gas atomized and spherical, is filled into a mould, usually a metallic "can". The can is vibrated ...
