What's the typical lead time for prototypes vs. production orders?

Prototype samples typically ship within 7–15 days depending on complexity. Production batches run 15–25 days after design lock. We coordinate lead-time planning during the RFQ phase so your project schedule is confirmed before PO release.

What quality certifications do you hold?

Our facility operates under ISO 9001 quality management. Products meet CE and RoHS/REACH compliance. For automotive programs we support PPAP documentation, and for medical applications we align with ISO 13485 process requirements.

How do you handle engineering changes during a project?

We use revision-controlled change flow with documented impact review on validation, quality, and delivery. Each change is tracked with before/after records so your team maintains full traceability across program gates.

What's included in your sample and pilot validation package?

Sample shipments include dimensional inspection reports, magnetic test records (gauss mapping or pull-force data), and material certification. For pilot builds we add process capability data (Cpk) and golden sample boundary documentation.

Can you share references or case studies from similar applications?

Yes. We can discuss application-relevant experience across sensor, motor, holding, and latch assembly programs. Contact our engineering team at inquiry@magnetassembly.com with your application context for a targeted discussion.
