PRODUCTION SHOW
Product Excellence
FDA Silicone Duckbill Valves Named for their distinctive bird-beak shape, our duckbill valves feature a simple yet highly effective one-way flow design. These valves open under forward pressure to allow fluid or gas passage, then seal tightly when pressure is released or reversed. This natural sealing mechanism eliminates the need for springs or moving parts, reducing maintenance requirements and extending service life.
Cross Slit Valves Our cross slit valves incorporate a precision-cut X-shaped opening that provides excellent flow control for both liquids and gases. The symmetrical slit design ensures consistent dispensing angles within ±15° while maintaining reliable sealing performance, even when inverted. These valves are particularly well-suited for squeeze dispensing applications where precise dosage control is critical.
Manufacturing Process & Quality Assurance
We utilize both LSR (Liquid Silicone Rubber) injection molding and compression molding to produce our silicone valves. LSR injection molding is ideal for high-volume production, delivering exceptional precision with tight tolerances and excellent surface finish. Our automated LSR molding lines can produce up to 10 million valves annually with consistent quality.
We source only premium-grade platinum-cured silicone rubber from trusted suppliers like Shin-Etsu and Dow Corning. All materials meet FDA 21 CFR Part 177.2600, LFGB, and USP Class VI standards, ensuring biocompatibility and safety for direct food and medical contact.
Our automated die-cutting systems ensure clean, precise slits with controlled dimensions. Each valve undergoes 100% visual inspection using CCD camera systems to verify slit geometry, placement, and overall quality before packaging.

FAQ:
Q: Are you manufacturer or trading company?
A: we are manufacturer.
Q: How to get the quickest quotation?
A: send e-mail with drawing directly.
Q: How to get quotation without drawing?
A: possible send sample, pictures or detail descriptions of products to us, we will return you drawing for confirm.
Q: I have an idea for a new product, but not sure if it can be manufactured. Can you help?A. Yes! We are always happy to work with potential customers to evaluate the technical feasibility of your idea or design and we can advise on materials, tooling and likely set-up costs.
Q: My custom products have already been developed on CAD. Can you use the drawings?
A. Yes! DWG, DXF, IGES, Solidworks and Rhino files can all be used to generate quotes, models and mould tools - this can save time and money in producing your parts.
Q: Can I test my idea/product before committing to mould tool manufacture?
A. Yes, we can use CAD drawings to make models for design and functional evaluations.
Q: What type of plastic material is best for my design/product?
A. Materials selection depends on the application of your design and the environment in which it will function. We will be happy to discuss the alternatives and suggest the best material.
Q: How about sample?
A: free sample is available for your quality evaluation, but you should pay the freight. Regarding customize products, sample and mould order will go first before mass production.
