Silicone Bellow Molding also called as  Automotive Rubber Bellows Molding, Rubber Expansion Joint Molding, Silicone Suction Bellows Molding, Rubber Dust Cover Molding, Bellows Suction Cup Molding, Liquid Silicone Bellow Molding, Rubber Expansion Bellows Molding and  Flexible & Inflatable Rubber Expansion Bellows molding, which are mainly designed to produce silicone bellows that can 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 Bellows normally work as a connector, protector, boots, hose and sleeve,etc. Silicone Suction Bellows also works to suck up the lable and stick it on the fruit through the customized holes by suction.

Silicone Bellow Molding includes Liquid Silicone Rubber Injection Molding for bellows and Solid Silicone Compression Molding for Rubber Bellow. Silicone Bellows made by silicone compression molding in solid silicone and rubber material according to different working environment. And for the holes, can demold directly or die cutting after the bellow is molded. While the holes are difficult to demold by compression molding, and rubber flashings left in the holes and can not debur easily. So to choose liquid silicone injection molding for production is a better choice.

Silicone bellows choose liquid silicone injection molding:

 

1.Complicated 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. High Production Efficiency

  • Silicone Bellow 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:
