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
