麻烦翻成中文.
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.
经加工的铝铸件
一共有16个部件,有些将近1.7米长,有些重12千克.它们都需要做33BAR,63BAR或99BAR的压力测试.
这些铸件有着很好的耐力和非常高的质量标准.
他们(合作商)想寻找一个正规的经营铝制品的公司,这个公司必须已经有过从事砂铸造及很好的加工经验,并可以进行铸件完整性测试.
我所获得的其他信息有:这些金属是LM25规格的,加工完成后,进行热处理,达到LM25TF.如果需要的话,我可以提供热处理过程(详情).此外,它只需要33BAR的压力测试.
