Hello Doris Wu, Thank you for confirming. I have updated the material on the order to black ABS. The customer accepts the change to have the parts split into pieces then glued together; please proceed. Thank you for working diligently to make the production of these parts possible; I appreciate the feedback and information you provide. Best regards,
Automotive Engineer
Hi Doris Wu, I appreciate the efforts. If we can get just 50 pieces out that will help the customer until the remaining parts are delivered so their inventory does not run out. Let me know what is possible as your team begins to return. Thank you.
Procurement Manager
Dear Doris Wu, the parts were successfully received by our customer yesterday. There were no damages, all in good quality. He gave very big praise to the packaging master. He has never received such well-packed sheet metal parts. Thank you for a great job!
