Links & levers
Pivoting or translating parts that transfer force between actuator, spring, jaw, latch or valve elements.
Links, levers, pawls, cams, forks, latches and retainers are best evaluated from load path, pivot/contact surfaces, fatigue, wear, geometry and repeat-volume economics before choosing MIM, PM or machining.
This family covers links, levers, pawls, cams, forks, latches, retainers and compact locking elements. The same component logic can appear in robotics, fastening tools, pruning equipment, valves or beverage hardware, so the page focuses on load path and interfaces rather than one end market.
Pivoting or translating parts that transfer force between actuator, spring, jaw, latch or valve elements.
Compact locking or indexing parts where tooth/contact geometry, fatigue and wear determine durability.
Profiled parts that convert motion or generate force, often with critical contact surfaces that may need heat treatment or finishing.
Feature-rich components with holes, bosses, pockets, hooks or cross-features that can make MIM attractive at repeat volume.
| Geometry / function | First route to evaluate | Why / watchout |
|---|---|---|
| Small 3D link / lever / latch | MIM — often a strong candidate | Integrated bosses, holes, hooks and thickness changes can replace several machining operations; fatigue and pivot/contact surfaces still need validation. |
| Cam / wedge with critical contact face | MIM + selective finishing, or CNC | Near-net geometry may be useful, but profile accuracy, hardness, surface condition and contact stress decide the final chain. |
| Press-friendly simple structural mechanism part | PM | Conventional PM can be efficient when features align with compaction direction and density/load targets are compatible. |
| Flat thin pawl / spring-like plate | Stamping / laser / machining | Simple sheet geometry usually should not be forced into MIM. |
| Low-volume or frequently revised mechanism | CNC / turning / fabrication | Tooling economics and design-change risk can outweigh near-net-shape savings. |
Mechanism DFM starts from the failure mode: bending, fatigue, impact, sliding wear, edge wear, pivot fretting or locking retention. Process choice follows the functional risk, not the part name.
SINTS component examples show linkage, toothed and integrated 3D geometries. Their suitability is reviewed against the drawing and operating requirements.

Forked ends, cross-features and near-net 3D form.
SINTS MIM referenceDefine pin fit, bearing length, wear surfaces and which bores require machining, reaming or other secondary control.
Cam, wedge, latch and pawl surfaces may need hardness or finishing beyond the primary MIM/PM geometry.
Cycle count, peak load and shock events should be shared early so material and heat-treatment choices are not made from geometry alone.
Springs, pins, bearings, housings and mating parts define tolerance stack and functional clearances.
