Medical Valve Body with Tethered Cap
Clear valve body with side ports and a living-hinge tethered closure cap.

Medical Valve Body with Tethered Cap
Medical Valve Body with Tethered Cap is one of the parts molded on tooling built at our Dongguan shop. Clear valve body with side ports and a living-hinge tethered closure cap.
The DFM we issue for a part like this carries the gating pictures, the main mold layout with dimensions, the parting and insert split lines and the ejection concept, and it goes to you for comment before fabrication starts.
Cavity and core steel is machined on our own CNC and EDM equipment, inspected dimensionally after machining, and the electrodes are checked for dimension and surface finish before they are burnt.
Key Benefits
- One shop from design through trial, with no tool transfer between vendors
- Design review meeting before the design reaches you
- Reply to every enquiry inside 24 hours
- A written DFM before fabrication, so changes happen while they are still cheap
Problems It Solves
- Suppliers who cannot read a mold standard written in English
- Warpage found at assembly rather than in the cooling study
- Cavity finishes agreed after the steel was cut instead of before
Who It Is For
- Disposable device manufacturers
- Diagnostic and laboratory equipment makers
- Fluid handling and infusion set assemblers
- Device OEMs qualifying a second tooling source
Application Scenarios
- Connectors, caps and port fittings
- Filter chambers and strainer inserts
- Diagnostic cuvettes and optical windows
- Clear housings, cassettes and covers
How the Tool Behind Medical Valve Body with Tethered Cap Is Built
- Design
Full 3D mold design completed to one hundred percent and checked in a design review meeting.
- DFM and MoldFlow
A written DFM for your comment, and filling, packing, warpage and cooling analysis on mass production tools.
- Machining
CNC and EDM work with steel inspected dimensionally after machining and electrodes inspected before burning.
- Trial and inspection
Mold trial with trial report and sample dimension report, then final mold and packing inspection.

Customization
Mold standard, cavity count, gating strategy, surface finish and mold base supplier are all specified per project. Tell us what your own standard requires and it is folded into the DFM rather than handled as a change later.
Compared With a Prototype Tool
A production mold for Medical Valve Body with Tethered Cap is built to run for more than 1 million shots and is documented with a trial report and a sample dimension report. A rapid prototype mold answers a different question — is the design right — at a lower price and a faster lead time, and is not built for that life. If the design is still moving, the prototype stage is usually the cheaper route into the production tool.
Rapid Prototype MoldsUse Guide
- Send 3D part data in STEP, IGES, Parasolid, CATIA, SolidWorks
- State the resin or alloy, the annual volume and the mold standard
- Comment on the DFM before fabrication — that is the cheapest point to change anything
- Review the trial report and sample dimension report against your own drawing before release
- Keep the mold standard on file so spares stay available locally

Is a prototype tool worth it before the production mold?
It is when the design is not yet frozen. Rapid prototype mold making is one of our listed services, priced low and built for a fast lead time, and what the trial shows feeds the DFM for the production tool.
How long does a quotation take for Medical Valve Body with Tethered Cap?
We return a professional mold quotation within 2 working days. Send the 3D data, the resin and the expected annual volume and that is usually enough to quote without a second round of questions.
Can you supply replacement inserts for a tool already in production?
Precision components making with CNC and EDM machining is a service we sell on its own. Send the insert drawing or the 3D data and we will quote it as a component job.
Can you work to our own mold standard for Medical Valve Body with Tethered Cap?
Yes. Mold design follows your own standard where you have one, and otherwise a global standard such as DME / Meusburger / HASCO / Progressive / MISUMI. Naming the standard in the enquiry avoids re-specifying components later in the design.
