About Us
Manufacturer of custom silicone and plastic tumbler accessories with tooling, molding, assembly and OEM/ODM support.
Custom Silicone & Plastic Components for the Drinkware Industry
Kunshan Fuhongying Electronic Materials Co., Ltd. was founded in 2018 and focuses on custom silicone product development, liquid silicone rubber solutions and supporting manufacturing services. For SiliconeTumblerAccessories.com, our manufacturing scope is organized specifically around tumbler, water bottle and thermal drinkware components.
We work with drinkware brands, product developers, importers, distributors and OEM/ODM programs that need customized parts rather than only standard retail accessories. Projects may start with an existing drawing, a 3D model, a physical sample, a target cup size or an early product concept.
What We Manufacture
Our scope covers silicone tumbler boots, silicone cup sleeves, grip bands, sealing rings, gaskets, straw toppers, straw caps, spill stoppers and other flexible drinkware accessories. For projects that also require rigid components, we can support plastic injection molded lids, handles, inserts and selected multi-material assemblies.
This combined approach is useful for customers developing complete lid systems, silicone-to-plastic interfaces, overmolded parts or accessory sets that contain several materials and require coordinated tooling, color matching and assembly.
Engineering and Project Support
- Drawing and manufacturability review for PDF, STEP and CAD files
- Material, hardness and structure recommendations
- Mold design and tooling development
- Prototype and sample production
- Silicone compression molding and LSR processing
- Plastic injection molding and selected overmolding projects
- Logo, texture, color and packaging customization
- Dimensional, visual and functional inspection
- Assembly and production coordination
Why Buyers Work With Us
For custom tumbler accessories, fit and consistency matter as much as appearance. A boot that is too loose can slip; a seal with the wrong compression can leak; a lid interface with uncontrolled dimensions can create assembly problems. We therefore focus on clear specifications, realistic tolerances, repeatable tooling and documented inspection points before mass production.
Our goal is to help customers move efficiently from requirement review to a production-ready part, with communication covering material selection, mold development, sampling, corrections, quality checks and shipment planning.
