Overview
The White Label 13.5 mm One-Way Squeeze Bottle Valve is engineered for high-performance ketchup and thick-sauce dispensing where drip-free, single-squeeze dosing is required. Manufactured using silicone compression molding, the valve is made from platinum-cured, food-grade silicone and designed for robust sealing, consistent flow control, and long service life. Fully OEM-capable, we offer custom diameters, slit geometry, hardness tuning, color matching, and private-label packaging.

Core Benefits
- Drip-free dispensing — engineered cross-slit geometry and optimized hardness deliver reliable single-squeeze dosing with no residual drips.
- Food-safe materials — platinum-cured silicone meets FDA/LFGB food-contact requirements for condiment use.
- Customizable flow — slit profile and Shore A hardness tuned to match product viscosity and target dispense force.
- Durable & repeatable — compression-molded parts provide consistent dimensions and long operational life across production runs.
Manufacturing & Process Notes
- Tooling — precision cavities are produced using CNC machining, mirror-finish EDM, and slow-speed wire EDM to achieve tight tolerances and smooth demolding surfaces.
- Molding — silicone compression molding with controlled cure profiles and vacuum de-airing produces consistent, low-flash parts ideal for elastic sealing features.
- Post-process — automated trimming, visual/vision inspection, and optional silicone passivation or surface treatment done before packing.
- Customization — Pantone color matching, logo emboss/deboss, and secondary overmolding/assembly services are available.
Quality Assurance & Test Capabilities
All valves are manufactured under an ISO 9001 quality system with multi-stage inspection: incoming raw material verification, in-process monitoring, and final QA.
Typical equipment & tests include:
- CMM for dimensional verification
- Shore A durometers
- Tensile/elongation testers
- Inverted leak/seal integrity testers (24–168 hrs)
- 3D optical projectors and vision systems for geometric/visual inspection
- Thermal cycling chambers for temperature stability
Third-party LFGB/FDA material testing is available upon request.
OEM Services & Capacity
We provide end-to-end OEM support — DFM, rapid prototyping, mold design and build, color & hardness formulation, tool trial runs, and scalable production.
Capacity highlights:
- Daily automated lines support high-volume output
