We have tried lower loading and slower rotation, but output drops. What else has worked?
- Barrel speed and reversal cycle
- Use of a hexagonal or octagonal barrel
- Cathode contact design
- Pre-treatment that reduces friction
We would like to solve this without changing the customer’s thread specification.
