Magnetic Particle Inspection for Ferromagnetic Fasteners
MPI can help identify surface and near-surface discontinuities in suitable ferromagnetic parts. It is one inspection method, not a substitute for material, dimensional and mechanical checks.
When to specify MPI
- Define the part material, inspection area and acceptance criteria.
- State the sampling plan or lot coverage in the purchase order.
- Confirm the report format and reference standard before production.
For sourcing
Share drawings, grade, lot size, applicable standard and inspection requirements. The inspection scope should be agreed before order confirmation.
