Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Diameter Range	D1mm - D100mm	Covers micro-sensors to heavy lifting

RFQ Checklist

Diameter and Thickness (D x T)
Grade (e.g., N35, N52)
Magnetization direction (axial/diametrical)

Risk Controls

Coating peel on edges: Specify tumbling and chamfering before plating

Buyer Decision Pack for Internal Approval

Most delays on neodymium disc magnets sourcing happen when engineering and procurement approve different assumptions. Use this section as a shared decision pack so RFQ, sample validation, and release criteria stay synchronized.

Decision Layer	Required Evidence	Approval Output
Technical Fit	Geometry and tolerance feasibility against assembly stack	Confirm drawing baseline and frozen revision code.
Validation Plan	Sample quantity, test method, and measurable pass/fail gate	Approve pilot scope and escalation path for deviations.
Commercial Release	Lead-time assumption, lot size, and destination terms	Lock PO terms only after technical/quality alignment.

Practical Notes for Repeat Orders

Keep a revision log for every engineering change and mark whether it changes function, coating, packaging, or only dimensional tolerance.
Ask suppliers to include outgoing inspection points directly in the quote stage so compliance expectations are visible early.
For forecast-driven programs, align quarterly demand visibility with buffer strategy before MP rollout to reduce expedite risk.
Archive sample pass evidence together with the approved RFQ sheet to speed up future model migration and reorders.

Operational Readiness Checklist Before PO Cadence

Teams usually avoid repeat-order surprises when they lock a single operational checklist before the first recurring PO cycle. This checklist should combine engineering constraints, quality evidence, and logistics assumptions in one version-controlled file.

Checkpoint	Minimum Evidence	Why Buyers Care
Drawing + Revision Lock	Active revision code tied to accepted sample report	Prevents quote and production from diverging silently.
Acceptance Rule Freeze	Measurable pass/fail limits for critical dimensions and magnetic output	Keeps sample and MP decisions consistent across teams.
Process Stability	Pilot-lot consistency records and deviation handling path	Reduces launch risk caused by single-lot bias.
Logistics Baseline	Packaging method, labeling fields, and shipping assumptions	Improves receiving predictability and import readiness.
Change-Control Ownership	Named contacts, notice window, and effective-lot rules	Avoids untracked process drift during repeat supply.
