Liquid Rubber Bellows


Liqud Rubber Bellows, also called as Liquid Silicone Bellows, LSR Silicone Bellows, Silicone rubber bellows, Custom Silicone Bellows, which are designed to protect against dust, oil,grease,water, acids, bleaches, spatter and other environment element to keep equipment performance in medical device, automotive, pumping, industrial usage etc.

Silicone Rubber Bellow is normally made by silicone compression molding in solid silicone and rubber material according to different working environment. Custom Rubber bellow has different working function: as connector, protector, hose and sleeve.


LSR Silicone bellows choose liquid silicone as material mainly because:

 

1.Product Structure:

For some special and complicated designs, can only make by liquid injection molding. The holes are small, and by compression molding, the bellow can not demolded easily and there will be rubber flashing in the hole. And for the silicone rubber bellows have high size and design tolerance requirement, Liquid Silicone Injection Molding is a better choice.

2. Material Advantages:

  • High Safety: Liquid Silicone Rubber material 100% food grade silicone, clean, plasticizer-free, tasteless, and can resist oxidation and bacteria growth. For Silicone Rubber Bellows that need to contact food and human contact equipment, Liquid Rubber Bellows are the best choice.

  • Wide Hardness Range: Liquid Silicone Rubber can achieve the lowest hardness 5 ShoreA, and highest 80A, which is a good property that compression molded rubber bellows can not achieve, for higher hardness, it's very difficult to demold; and for low hardness, the parting line will broken easily.

  • Durable: Liquid Silicone Bellow has better elongation, higher tear and tensile strength, and excellent flexibility.

  • Wide Temperature Resistant: LSR Silicone Bellows have large temperature range ( –60°C to +180°C.), can withstand extreme high and low temperatures. For silicone bellows that work in machine environment, liquid silicone is a better choice.

3. Production Efficiency

  • Liquid Silicone Bellows by Liquid Injection Molding can demold automatically and with no or less rubber flashings, which can save human labor to deal with the rubber flashing manually.

  • Shorter Cycle time, do not need to place material by hand like compression molding, and the curing time is also shorter.

Compression Molded Silicone Rubber Bellows' Advantages:

Custom Silicone Bellows by Compression molding is cost economic compared to LSR injection molding.

With the development of industry, the tolerance of rubber bellow can achieve at 0.02-0.1mm by using good mold steel material, good located pins, and good mold-making equipment.



Compression molding is availabe for different kinds of silicone rubber materials according to different working environment.  The most common materials include silicone bellows, natural rubber bellows, and EPDM bellows, NBR bellows. Please check different properity for different material bellows:
