When is MIM a good fit?
MIM may fit small, complex 3D metal parts when geometry consolidation and repeat volume justify tooling. Material, distortion risk, critical datums and secondary finishing still need drawing-level review.
SINTS helps OEM engineering and sourcing teams review geometry, material, annual volume, critical interfaces and finishing needs before deciding whether MIM, powder metallurgy, gear manufacturing, machining or a hybrid route is the better fit.
SINTS has manufactured powder-based metal components since 1995. Today the manufacturing platform combines PM, MIM, gear-related production, secondary machining support, tooling, inspection and project-specific finishing — with the route selected from the drawing rather than from a sales template.
The Zhongshan and Jiangxi production bases provide about 45,000 m² of combined manufacturing area. For new programs, the engineering discussion starts with part function, geometry, material, critical datums, load or wear conditions, annual demand and the surfaces that may need secondary control.
The product library now separates what the part does from where it is used. Start with the functional family, then use the application guides to add load, wear, environment and assembly context.

PM and MIM are core manufacturing routes, with gear, machining, tooling, inspection and project-specific secondary operations considered when the drawing requires them.
The Zhongshan powder-metallurgy manufacturing scope is IATF 16949:2016 certified. FAI, PPAP and other documentation are defined according to the customer program.
Zhongshan and Jiangxi provide complementary manufacturing capacity. The exact production site and supporting operations are confirmed during project review.

Send a 2D drawing or 3D CAD file with material, annual volume, application, critical dimensions, finish, inspection requirements and target timing whenever available.
Yes. Dimensional reports, material confirmation, FAI, PPAP and other quality documentation can be planned when required by the drawing or customer program.
Each stage is defined by the drawing, tooling route and customer approval requirements rather than by a universal lead-time promise.
