Pump Housing Appearance Defect Inspection

Surface defects like porosity or machining flaws can cause pump housings to crack under pressure, leading to failures, seal issues, and higher costs—so visual inspection prevents defects from reaching later stages and protects reliability and reputation.

Project Overview:

  • Product: Pump Housing (Size: 60×60×70mm)
  • Project Goal: save labor costs and enhance product quality through AI-driven inspection. Remote update modules are needed for future projects.
  • Defect Types: Scratches, pits, material loss, incomplete machining, peeling, color variations, porosity, dents, etc.

Solution:

Housings travel on a servo-driven conveyor beneath four 4 inspection stations, where Cortex Edge instantly analyzes high-contrast images to spot sub-millimeter flaws and route good parts to the pallet carousel while diverting rejects for rework.

Vision System Components:

  • AI Central: CorteX Central *1
  • Imaging System: OptiX *4
  • Inspection Cell: CorteX Edge *1

UnitX Case Study

Results:
  • The system delivers fully automated inspections with False Acceptance Rate (FA) =0 for critical defects and an overall False Acceptance Rate (FA)≤0.5% for all other defects.
  • False Rejection Rate (FR) ≤5%
  • Cycle Time: 5s/each
