I am looking for a list of companies/institutions that have Hot
Isostatic Pressing (HIP) capabilities in China, with own equipment
installed and running in this country.

I expect a list of at least 15-20 companies/institutions (in an MS
Excel spreadsheet) with their name, HIP equipment installed (small vs.
large HIP vessels), product lines that use HIP capacity, industries
served, address, web address, and any observations you'd find
noteworthy, ideally any information regarding their size (revenues,
number of employees, production capacity).

For reference, an example of a Chinese company with HIP capacity is
AT&M http://www.atmcn.com/English/Home/

To learn about HIP, refer to the website of a major Western player in
this area http://hip.bodycote.com/
