Metal injection
molding services.
Evaluate MIM for small, complex metal parts in repeat production. Bring geometry, material, tooling and finishing into one project discussion.
A route for small, complex metal components.
Metal injection molding combines fine metal powder with a binder, molds that feedstock, removes the binder and sinters the component. Tooling, shrinkage control and secondary operations are part of the manufacturing assessment.
MIM is worth evaluating when complex small components are needed in repeat production. Partavon helps coordinate that evaluation against your geometry, material, quantity and required part condition.
Review the part before investing in tooling.
The first discussion should establish what the component must do and which features are critical. Wall transitions, unsupported features, parting lines and the sintering approach can influence the final manufacturing plan.
A quotation should separate the tooling investment from the recurring part cost and explain sampling, tooling revisions, inspection and any secondary machining. There is no universal break-even quantity that applies to every MIM part.
- Part geometry and critical interfaces
- Material grade and required finished condition
- Expected annual demand and order pattern
- Tooling, first samples and approval criteria
- Secondary machining, heat treatment or finishing
Material-specific requirements matter.
Stainless grades such as 316L and 17-4PH are common starting points for MIM discussions, but the material name alone does not define the finished component. Powder availability, process route, heat treatment and acceptance requirements still need confirmation.
If you specify 17-4PH, include the required condition and relevant properties. If you specify 316L, describe the corrosion environment and any finishing or test requirements. Material data and certificates must relate to the agreed project, not a generic website value.
From feasibility to approved production.
The project sequence is drawing review, tooling quotation, tool development, trial samples, agreed verification and production approval. The scope and timing of each stage should be confirmed before placing the order.
Where required, critical interfaces may need secondary machining. Make the distinction between as-sintered and finished dimensions clear on the drawing. A CNC-machined sample can help evaluate geometry, but it does not by itself validate MIM material or sintering performance.
| Project detail | What to include |
|---|---|
| CAD and drawing | Geometry, part weight if known, critical dimensions and revision |
| Material | Grade, condition, required performance and finishing |
| Demand | Initial order, annual forecast and expected order frequency |
| Verification | Sample approval criteria and required inspection documents |
| Commercial scope | Tool ownership, tooling changes, packaging and delivery |
Before the quotation.
Is there a fixed minimum order quantity?
The accepted quantity and economic case depend on tooling, geometry, material and production planning. Submit the first-order quantity and expected annual demand for a project-specific assessment.
Can MIM replace my CNC-machined part?
Sometimes. Review geometry, material performance, annual demand and secondary operations together. The comparison needs to include tooling and sample approval, not only the recurring unit price.
Will every feature be finished directly by molding?
Not necessarily. Critical bores, threads or mating interfaces can require secondary operations. Those operations should be identified in the manufacturing plan and quotation.
