I have great news to share!
We recently visited both Western Digital and MMi. We had an amicable meeting with the SQE team and also Khun Jirakul and Mr Fernando. They have confirmed with us how the chemical approval process works.
MMi works closely with Western Digital and has given ACP the flexibility to use whichever chemicals on the line so as that the quality of the final product meets the requirements. The only item that cannot change is the ecoat Nippon paint.
Our technical staff Non has recently been testing our cleaner and has shown good results at your facility. My understanding is that ACP still has Okuno stock left.
I request that we work together on testing the aluminium etching and chrome-free passivation at your facility. Our chrome-free passivation has polymer components in therefore there is no residue after the passivation. This means water rinse can be skipped and go immediately into baking and e-coat.
We are confident our epunion series will be able to match the requirements and our pricing is much more competitive and can assist ACP with savings to its bottom line.
