machined aluminium castings.
There are 16 parts,some nearly 1.7m long,some 12kg in weight and they need pressure testing to 33,63 or 99 bar.
There are very fine tolerances,and very high quality standards.
They want to find a company who works with Aluminium regulary,already does sand castings and fine machining,and can test for integrity in the castings.
Other information I have been given is that the metal is LM25 and then after casting and before machining it,is heat treated to make it into LM25TF.I have the heat treatment process if needed.
Also it only needs pressure testing to 33 bar.
