Silicone Control Valve Production Flow

At the very beginning, we choose the high precision LSR injection molding, the tolerance will be much tighter than compression molding, which is why we can guarantee to our customers that there is no leakage after 7 days/ 24 hours inverted leak proof testing. Our production line is very flexible, no matter is small order at prototyping stage, or large order at peak seasons needs, we can adjust our punching line to meet the production schedule.

Why Choose Yejia Silicone

For over 13 years, we focus on manufacturing optical grade, medical grade and food grade custom liquid and solid silicone molding products, for customized silicone check valves, we'd recommend to start with prototype mold to validate at first, the prototype mold lead time is usually around 7-10 working days. After validation, we'll move forward to mass production mold, it takes 15 to 25 working days, depends on the product structure.
