Functional interface
Define what passes through, fits into or locates against the insert, and whether there is relative motion.
NON-THREADED INSERTS
Bushings, Sleeves & Non-Threaded Inserts
Add a defined metal bore, locating surface or spacing feature to a plastic component with a custom bushing or sleeve.
HOW IT WORKS
Understand the installation and function.
Non-threaded inserts can provide a metal interface for location, spacing or reinforcement. A bushing is not automatically a compression limiter or a bearing: its intended function determines the design.
Where to start
Custom plastic assemblies that need controlled bores, stand-off geometry or a durable mating interface. Share the complete assembly so the role of the insert is clear.
APPLICATION REVIEW
What we review with you.
Geometry and datums
Supply bore, outside profile, length, shoulder and the surfaces used for positioning.
Retention
Identify molded-in or post-mold assembly and the features needed to resist movement.
Material and finish
Define material specification, contact conditions, corrosion exposure and surface requirements.
CUSTOM OPTIONS
Define the features your assembly needs.
Plain, flanged, stepped and grooved sleeves, locating bushings and combined features can be reviewed. Critical fits are manufactured to an agreed drawing.
| Requirement | Useful RFQ information |
|---|---|
| Thread / bore | Standard, pitch or bore fit; usable engagement and mating hardware |
| Envelope | Body dimensions, shoulder, flange, location and surrounding clearance |
| Material / finish | Specified grade, surface treatment and service environment |
| Volume / timing | Sample quantity, order quantity, repeat demand and required delivery |
| Acceptance | Drawing revision, critical dimensions, sample checks and documents |
COMMON QUESTIONS
Before you send your RFQ.
Can you work from an existing sleeve?
Yes. Send clear photos and key dimensions first. A physical sample and mating-part information may be needed to establish a production drawing.
Can these be supplied with internal threads?
If the design requires a threaded interface, we can review that as a threaded or multi-feature insert rather than treating the bore as a plain sleeve.
YOUR NEXT STEP
Discuss your bushings, sleeves & non-threaded inserts.
A drawing, a sample photo or a clear description is a good place to start.
