Syringe And Catheter Components
Disposable Syringe Components
Molded barrels, plungers, flanges and colour coded syringe parts for single use delivery devices.
Product Overview
What This Component Is
Molded barrels, plungers, flanges and colour coded syringe parts for single use delivery devices. The plunger to barrel fit determines both the seal and the feel of the device, and it is set in the tool.
Key Benefits
- Barrel and plunger cavities held in the same plant so the fit is tuned once
- Colour coding molded to your standard across the family
- Automated molding workshop sized for delivery device volumes
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
- Injection device makers
- Dosing product brands
- Contract manufacturers of single use devices
Problems It Solves
- Plunger seal that drags or leaks depending on the lot
- Flange geometry that breaks under thumb pressure
- Colour coded families produced across several molders with no shared reference
Application Scenarios
- Single use injection devices
- Oral and enteral dosing syringes
- Instrument fluid dosing
Technical Features
How It Is Engineered
- Barrel bore and plunger diameter toleranced as a pair
- Flange rib sections reviewed for strength without sink marks
- Graduation and colour handled in the tool rather than after
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
| Buying barrel and plunger separately | Seal and feel are properties of the pair. Two suppliers produce two tolerance stacks and a device that feels different lot to lot. |
|---|---|
| Stock syringe components | Stock parts fix your graduations, your colour coding and your flange shape. Tooling lets the device be yours. |
Use Guide
How To Handle It
- Qualify plunger force after conditioning, not straight off the machine
- Test flange strength with a gloved hand and real thumb pressure
- Keep the colour reference in your incoming inspection record
Questions Buyers Ask
Questions About Disposable Syringe Components
Do you have experience with delivery device molds?
Our high precision mold room is mainly responsible for medical and plug in molds with accuracy controlled at 0.002 mm, which is the class of work syringe tooling sits in.
Can you mold the whole syringe family?
Yes, and holding the whole family is how the colour standard and the fit stay consistent.
Do you assemble or sterilise?
We mold and clean room pack. Assembly, sterilisation and device release stay with your registered manufacturer.
