Liquid Silicone Diaphragm

Silicone Diaphragm Seal, also known as Liquid Silicone Diaphragm, LSR Diaphragm Seal, Rubber Membrane, Diaphragm Sheet, Membrane Valve, which is flexible silicone rubber sheet that placed in a certain device works as a sealing to provent unwanted transimission of substances, which usually works at low pressure flow control application to control liquid, gase etc.

Liquid Silicone Diaphragm


Liquid Silicone Diaphragm, also known as Silicone Diaphragm, LSR Diaphragm Seal, Rubber Membrane, Diaphragm Sheet, Membrane Valve, which is flexible silicone rubber sheet that placed in a certain device works as a sealing to prevent unwanted transimission of substances, which usually works at low pressure flow control application to control liquid, air etc.

Liquid Silicone Diaphragm is made of high purity, clean and tranparent food grade & medical grade liquid silicone by liquid injection molding or silicone trasnfer mold. While for some rubber Diaphragm seal that do not have high material safety requirement or dimension tolerance demands, compression molding is enough for production.

Liquid Silicone Diaphragm's Molded Methods Comparasion: Liquid Injection Molded, Silicone Transfer Molded and Silicone Rubber Compression Molded:

  • Precision

LSR Injection Molding >Silicone transfer injection molding > Rubber Compression Molding

Liquid Silicone Injection Molded Diaphragm Seal, the amount of material is controlled by needle valve and go througn the sprue to each cavity, the material amount is precise so the dimension is preciser and can achieve strict tolerance and with no rubber flashing.

liquid silicone diaphragm

Liquid Silicone Diaphragm  by Silicone Transfer Injection Molding, the raw material is solid and put into the pot, with high pressure and temperature, the material will transfer into liquid and then transfer to cavities.

Transfer Injection Moulding for rubber diaphragm seals

Silicone Diaphragm Seals by Compression Molding, the raw material is placed into cavities directly after weight by workers, so the dimension precision is the lowest.


  • Material Waste

Silicone Transfer Injection Molding > Rubber Compression Molding >LSR Injection Molding

Silicone Transfer Injection Molding is the most material waste molding method, large amount of flashing will occur on the pot after curing, sometimes the waster material's weight is much more than product itself.

Silicone Rubber Diaphragm works in different areas, which can work as pressure gauge, pressure transmitter, sanitary, medical devices (like diaphragm valve in ventilator), and breast pump diaphragm etc. In different working areas, we can choose different material with unique properties. Common rubber material includes: Nitrile, EPDM, Fluorocarbon, Neopreme, Flrosilicone Rubber(FVMO) and silicone.
