- Inspection
- Engagement and retention in the specified assembly
Product Overview
SLS polymer parts may be used to evaluate selected mechanical functions, including assembly movement, fit and retention.
Their suitability depends on the specific material, géométrie, printing conditions and test requirements.
A successful test on one material or finishing condition should not automatically be applied to another.
Key Features
- Consider an illustrative SLS-printed cover containing a flexible clip.
- During installation, the clip deflects as it passes a mating catch.
- It must then recover sufficiently to engage the catch and provide the specified retention.
- The result depends on clip geometry, material response and the mating surface condition.
Manufacturing Considerations
- Before a functional trial, define the relevant polymer grade, mating geometry, installed position and finished contact surfaces.
- Where repeated opening and closing are required, establish the cycle count and acceptance criteria.
- Load, temperature and other operating conditions may also be relevant to the intended application.
- The evaluation may indicate a need to adjust clip geometry, clearance or material selection.
- Design revisions should be approved before additional samples are manufactured.
- Functional testing arrangements are confirmed according to the project scope.
Contrôle de qualité & Inspection
- The trial should verify whether the assembled cover meets the specified engagement and retention requirements.
- If the sample uses an alternative material, conclusions should be limited to the tested configuration.
- Material-sensitive results should not be described as evidence of production performance without appropriate justification.
Specifications to Confirm
| Trial material | Identify the grade or material properties that the trial depends on. |
|---|---|
| Géométrie d'assemblage | Specify the mating component and installed position. |
| Contact condition | Record the finished state of contact surfaces. |
| Cycle and retention criteria | Agree on the opening and closing cycles and the required engagement and retention. |
Assembly Considerations
Installation direction
Show how the clip approaches and passes the mating catch.
Engagement
Check that the clip recovers and seats against the specified mating part.
Retention
Check the assembled cover after the agreed cycles under the specified conditions.
