Perimeter gaskets for rectangular or shaped covers where corner geometry, retention and closure force govern the fit.
Frame gaskets serve a different task from a circular ring: the corners, narrow legs and cover hinges can make compression uneven. Show the full frame and the mating cover, including any localized changes in gap.
Explain whether the gasket sits in a groove, lies on a flat land or needs temporary retention during assembly. A molded section and a flat-profile frame are different design routes. The proposal should state which geometry is being evaluated.
A gasket illustration cannot prove an enclosure protection level. If a water, dust or leak requirement applies, define the complete assembly test, including closures and cable penetrations, and agree the acceptance criteria.
No. Identify whether the design calls for a flat-profile frame or a shaped molded section; the route is reviewed for the project.
An enclosure rating depends on the complete assembled product and its test conditions. It should not be inferred from a loose gasket.
These references explain general engineering or regulatory context. They are not Xinwei finished-product specifications, test results or compliance evidence.
SPECIFICATION REFERENCE
These are project discussion inputs. Compound, tolerances and validated performance require agreement for the specific part.
| Selection / definition | Reference and project conditions |
|---|---|
| Frame outline | Overall width/height, internal opening and radii in mm |
| Section | Flat thickness or molded cross-section in mm |
| Closure | Assembled gap range, fastener/latch locations and stops |
| Retention | Groove dimensions or approved temporary retention method |
| Joint policy | Allowed joint locations or continuous-only requirement |
| Validation | Cover fit, closure function and agreed ingress/leak conditions |
KNOWLEDGE & SELECTION
