IV Catheter Components
Molded hubs, wings and housings for intravenous catheters, shown here coming off the production line.
Product Overview
What This Component Is
Molded hubs, wings and housings for intravenous catheters, shown here coming off the production line. Concentricity between the hub and the needle is the whole engineering problem, and it is decided by core alignment in the tool.
Key Benefits
- Core alignment designed for hub concentricity rather than for easy molding
- Colour coded by gauge to your standard across the family
- Molded and packed in the ISO 8 clean room
Molded on tooling we cut ourselves in Shenzhen. Certification covers the site doing the work: ISO 9001:2015 and ISO 13485:2016.
Who It Is For
- Catheter manufacturers
- Infusion device brands
- Contract assemblers of vascular access products
Problems It Solves
- Concentricity failures that only appear after needle assembly
- Wings that flex differently between lots and change the taping feel
- Gauge colour coding drifting between production sites
Application Scenarios
- Peripheral IV catheter assemblies
- Safety catheter housings
- Infusion access devices
Technical Features
How It Is Engineered
- Hub core alignment held through the tool rather than corrected at assembly
- Wing flexibility reviewed against the resin your device file specifies
- Colour reference held against the tool record for repeat orders
Materials
- Medical grade resin selected against your specification rather than substituted by us
- Customer nominated grades accepted where a device master record already fixes the material
- Colourants and additives confirmed in writing before the first sampling run

Figures above are plant and tooling capabilities recorded on our own site. Part level tolerances are confirmed against your drawing at mold flow review rather than quoted as a blanket number.
Manufacturing Process
- Mold design review
- Steel machining and EDM
- Mold trial and cavity sampling
- Clean room or conventional molding
- In process dimensional check
- Clean room packing
Quality Control
- Cavity by cavity dimensional sampling before a tool is released
- In process checks during the molding run rather than only at the end
- ERP system records the lot, tool and machine behind every shipment
Customization Options
- Cavitation sized to your annual forecast instead of a fixed standard tool
- Colour and resin grade to your specification
- Clean room packing format and labelling agreed before the first shipment
Comparison
Compared With Other Routes
| General purpose molders | Hub concentricity is a tooling problem. A molder without a tool room can only send the tool away and wait when it drifts. |
|---|---|
| Splitting hub and wing suppliers | The parts are assembled together and felt together by a clinician. One plant keeps the feel consistent. |
Use Guide
How To Handle It
- Qualify concentricity after needle assembly, not on the hub alone
- Confirm gauge colour against your published standard at incoming inspection
- Keep components bagged until the assembly station
Questions Buyers Ask
Questions About IV Catheter Components
Can you hold hub concentricity?
It comes from core alignment in the tool, which our own tool room designs and maintains. We verify it on sampled parts with your needle where possible.
Do you mold in a clean room?
Yes, ISO 8, and parts are packed inside the same controlled area.
Can you support a gauge colour coding standard?
Yes, when the standard is supplied. The reference is recorded against the tool so repeat orders match the original.
