Engineering Case Notes

Engineering examples for manufacturing-route selection

Illustrative engineering note, not a documented customer production case. No achieved cost, yield or delivery result is claimed.

These illustrative engineering reviews compare MIM, powder metallurgy, CNC and hybrid routes using geometry, material, tolerances, volume and validation requirements.

Process Evaluation

Three examples, three different manufacturing questions

The point is not that MIM or PM always wins. Each example starts with a different bottleneck and shows what must be checked before changing the route.

17-4PH Lock Cam: CNC → MIM Evaluation

When complex profile, repeat volume and selective critical dimensions may justify moulding most features and finishing only what matters.

Decision Logic

When a conversion is worth modelling

Strong candidate

Repeat production, complex geometry, high machining content and a limited number of truly critical dimensions.

Worth modelling

The part has a mix of mouldable/sinterable features and a few surfaces that can be finished after sintering.

Poor candidate

Prototype or low volume, frequent design changes, large geometry, or a drawing dominated by tight tolerances everywhere.

We will compare process fit first. If machining remains the better route, we will say so.
