Problems encountered by customers
- A customer of an industrial manufacturer in Pakistan pointed out that hand-polished belts resulted in uneven surfaces on the slender stainless steel tubes and nozzle tips, leaving visible longitudinal scratches (Ra > 0.08 μm).
- Rough inner bore surfaces led to residue buildup within the dental impression filling machine and inconsistent flow rates.
- Rounded edges on critical sealing surfaces caused leaks and frequent recalibrations, resulting in a scrap rate as high as 18%.
Weshining’s solution
- Achieved a flawless, isotropic finish of ≤0.02 μm Ra on both external complex profiles and internal bores – eliminating residue adhesion and ensuring stable flow.
- Reduced polishing time from 50 min to 7 min per part – 86% faster.
- Zero edge rounding on sealing surfaces; 100% first-pass quality, saving the lab CAD $3,500/month in scrap and rework costs.
