## Content

**Intro:** A MIM supplier can only give a useful feasibility answer and tooling price if the request describes the part, the critical features and the volumes. This template collects that information in one document and asks the questions that surface risk early.

**Sections:**

#### How to use it

**Body:** Fill in the part summary, volumes, tolerances and secondary operations, then list the critical-to-quality features with their tolerances and measurement methods. Attach the 3D model and drawing. Use the supplier questions as the structure for the response, so every bidder answers the same things and you can compare quotes. Export to Word to add your terms and conditions, or to PDF to send as-is.

**Bullets:**

- Give a realistic annual volume, since it drives cavity count and tool cost.
- State the real minimum density and property requirements.
- List critical features separately from general tolerances.

#### Why these fields

**Body:** Mass, envelope and wall thickness decide feasibility: MIM suits small, complex parts, often under 100 g, with walls above about 0.5 mm. Volume determines multi-cavity tooling and whether MIM beats machining or casting. Material and density define sintering conditions and properties. General tolerance sets expectations for as-sintered capability, with sizing or machining reserved for critical features. Secondary operations and documentation drive cost and lead time beyond the molded part.

#### Reading the quotes

**Body:** Compare tooling price, cavities, expected tool life in shots, piece price at each volume tier, minimum order quantity and lead time to first article. Ask what the quote assumes about shrinkage correction, because iterative tool corrections are a real cost. Look at supplier answers on gate location and witness marks, since cosmetic and datum surfaces are often compromised by gate and ejector placement. A cheaper piece price with a looser capability statement can cost more after secondary operations.

#### Common mistakes

**Body:** Sending only a 2D drawing without the model slows feasibility review. Over-tolerancing every dimension forces machining that cancels MIM's cost advantage. Omitting volume tiers hides how piece price falls with scale. Another mistake is not stating datum surfaces and cosmetic faces, leaving gate and ejector placement to chance. Finally, request first-article measurement of shrinkage-sensitive dimensions and agree on tool correction rounds before placing the tool order.

**Cta:** If you manage supplier quotes, tooling and first-article approvals across many parts, we can structure that workflow inside your ERP and quality system.

**Faq:**

#### What parts are good candidates for MIM?

**Answer:** Small, geometrically complex metal parts in higher volumes, typically a few grams to under 100 g, where machining would be slow and casting cannot hold the detail. Volumes of tens of thousands per year and above justify the tool.

#### How much does MIM tooling cost?

**Answer:** It ranges widely with complexity, cavities and mold steel, from a few thousand dollars for a simple single cavity to well beyond that for multi-cavity or side-action tools. Treat any number as an estimate and request itemized supplier quotes.

#### What tolerance should I ask for?

**Answer:** A planning figure is about +/-0.3 to 0.5 percent of the dimension as-sintered. Apply tighter values only to a few critical features and agree on how they will be achieved, such as sizing or machining.

#### Do I need a prototype before tooling?

**Answer:** Often yes. Prototypes can be machined, 3D printed or made from a soft prototype tool. Remember that printed or machined prototypes do not show the shrinkage, density and gate effects of true MIM, so confirm with a first-article run.
