Customized Neoprene Nitrile EDPM Silicone Rubber Bellows
Rubber Bellows are used as a cover or expansion joint to protect device or machines, which are made by rubber compression molding, rubber injection mold or extrusion tool.
Rubber Bellows are designed as a cover mainly protect against dust, water, oil, grease, acids, bleaches, spatter or other environment elements.

Different Silicone Rubber Bellows durometer demands, surface demands, parting lines demands or rubber flashing demands have different production difficulty and production cost. Epecially for mold-making technology demands, compression mold steel choice, mold maintain when mass production etc.
Custom Rubber Expansion Bellows Requirements:
1. Offer 2D, 3D design drawings or samples, and also tell us your sizes telorance demands.
2. Bellows Materials Demands: Rubber, Silicone, EPDM, Nitrile, etc, or tell us operating environments, functions etc.
3. Durometer Demands (Hardness Shore A):
4.. Silicone Bellows Surface Demand
5. Working Environmment Demands
6.Silicon Bellows Flashing Demands etc.
How far apart should expansion joints be?
10 feet
The suggested distance between expansion joints is 10 feet. They should be placed at least this close together to ensure that the concrete slabs do not crack or break. Of course, this distance can be less if the slab that you are working on is not very large.
How do you cover expansion gaps?
There are a range of ways to cover the expansion gaps in your timber floor -- take a look at these ideas:
Use baseboards. Baseboards are one of the most common and simplest ways to cover your expansion gaps. ...
Embrace transition strips. ...
Rout the bottom of door frames. ...
Allow expansion with other materials
How long should Wall be before expansion joint?
within 6 months
Typically, most expansion occurs within 6 months, but as the process is irreversible, this movement needs to be accommodated by using movement joint fillers, or expansion joint foams. Thermal expansion can cause the bricks/walls to creep and warp, especially during dry cold weather.
