Buyer Questions

A faster way to assess process fit

Clear answers for engineering and procurement teams comparing MIM, powder metallurgy and CNC suppliers.

When is MIM a good fit?

MIM is suited to small, complex metal parts that need repeatable geometry and production volumes that justify tooling. SINTS reviews geometry, material, annual volume and critical tolerances before recommending a route.

What should be included in an RFQ?

Send a 2D drawing or 3D CAD file with material, annual volume, application, critical dimensions, finish, inspection requirements and target timing whenever available.

Can SINTS support quality documentation?

Yes. Buyers can request first-article samples, dimensional reports, material confirmation, PPAP-style documentation and production packaging review according to project requirements.
