Today, we finished the samples-wrench or MIM spanner to a customer near our factory. 

This is a new sample, having irregularly outshape. The biggest difficulty is the thin wall only about 0.5mm for 4 sides. Also the surface requirment is very high, need polish by hand, then shinning chroming coating.

Here below please see picture.  Salt spray testing,adhesive force testing and high temperature testing are all included.

We have a strong telant team to follow this program.
