Hi,
I preparing the drawing for a magnesium die casting enclosure of a medical hand held device. I know that the part will be made overseas and I would like to specify a set of standards to be followed to ensure a good quality of the product and to have some control over the chemicals and operations applied to the part. My intention is to have some notes as following:
1. Enclosure material: AZ91D
2. Cast treatment: machining, deburring, grinding, bead blasting
3. Cleaning (alkaline)
4. Activation (acid pickling)
5. Conversion coating (chrome free)
6. Finish painted (not decided yet what type of paint)
7. All processes to be RoHS complient.
Please let me know what standards should be specifed for these operations or if you work for a die casting company what notes you would like to see in the drawing.
I appreciate any feedback from you.
Thank you,
Dan Pop
