I started jewelry business in Indonesia. Recently, my production
rate is about 400 pieces a day. It is impossible for me to polish
them one by one. Therefore, I need help for:
How to get homogeneous color outside and inside the ring
(specially inside the prong).
Good mass finishing system.
The best and the cheapest chemical coloring.
This time, I=92ve used the following finishing system:
Vibrator (with stainless steel shot).
Thank for all answers you may have. Best Regards Peter.
