Dear Pun
We received the defect samples today.
We found the problem is the lacquer of metallization is harder. The Scratch resistance degree close to "1H". The current lacquer is suitable for small print area when doing the metallization process.
However, the outer cap of G7570F is thin and the diameter is wide (big). When we assemble the inner cap into the outer cap, the lacquer of outer cap will be strained because of the surface tension when assembled. It looks like the scratch but it is rift for sure.
We come up with the solution which is using soft lacquer instead of current hard lacquer so the cap will not be cracked. However, the scratch resistance degree could not achieve to 1H but close to “HB”.
We are really sorry for the inconvenient cause to you. Could you let me know the quantity of rift cap please?
We will send you replacement as soon as possible.
With Best Reagrds’
