Industrial Equipment — Precision Filtration Components
The requirement
Food-grade 316L filter cups with uniform 0.2 mm apertures, mirror-polished internal surface and repeatable flow rate across production lots.
Our solution
Flat aperture etching before deep drawing, annealing between operations, electropolishing and passivation, 100% visual plus sampled flow testing.
The outcome
- Flow-rate variation within ±3% between lots
- Residue-free surface validated for cleaning cycles
- Stable 2-week replenishment cycle established
