For product designer, silicone one way valve is a very good sealing product for sports bottles and squeeze bottles, because it not only has great sealing effect, but also can control the fluid flow. But how to make the silicone to be flexible and tough at the same time? Overmolding process will be a great solution for those products, this kind of technics can keep the product shape not deformed while not effect the flexibility of silicone raw material. If you're looking for custom silicone overmolded products, welcome to contact us.
