Leak Proof Flow Control Silicone Valves

Silicone valve is an elastomeric valve, also known as silicone valve seal, silicone rubber valve, silicone non return valve, silicone check valve, silicone control valve, silicone slit valve and silicone dispensing valve, made of silicone materials and processed by silicone molding, either compression molding or liquid injection molding. A silicone valve is designed to better control flow fluids at preset forces and vacuums. It opens and closes at a certain pressure, usually, to be used to dispense liquids, powders or gases.

Silicone Valves Production Processes

For many customized silicone valves, since the opening pressure and flow rate will be different, so the requirements for wall thickness, radian, slit cuts are different. Silicone valves can be processed by compression molding or LSR injection molding, depending on product structure and quantity demanded. Also, the punching tools are unique for each design. As the top manufacturer of leak proof silicone valves, our factory has achieved the automatic punching for silicone valves.

Normally, the production processes for silicone valves are as below.

  • Step 1: Materials Preparing: silicone materials can be divided into solid silicone and liquid silicone

  • Step 2: Silicone Molding: processed by vacuum compression molding machine or LSR injection molding machine

  • Step 3: Deflashing: to remove the extra burrs

  • Step 4: Slit Punching: the slit cuts to be done by manual/ automatic punching machine

  • Step 5: Shape Punching: punch the silicone valve to single piece

  • Step 6: Dust Free Packaging: use an air gun to remove the dust and dots from products and pack into bags and cartons

  • Step 7: Shipping: check with customers to confirm the most suitable transportation method
