Molded Moving Components Flexible Expension Joint Rubber Bellows for Pipe/Piping
Rubber Bellows is used as a cover or expansion joint to protect device or machines, which is made by rubber compression molding, rubber injection mold or extrusion tool.
Rubber Bellows is designed as a cover mainly protect against dust, water, oil, grease, acids, bleaches, spatter or other environment elements.
Rubber Bellows-Materials Ddoption
Rubber Bellows-Some Typical Applications:
Expansion joints
Rod & Ball screw covers
Piping penetration seals
Fan duct connections
Compressor and engine intake and exhaust manifold connections
Custom Rubber Bellows Requirements:
1. Offer 2D, 3D design drawings or samples, and also tell us your sizes telorance demands.
2. Rubber Bellows Materials Demands: Rubber, Silicone, EPDM, Nitrile, etc, or tell us operating environments, functions etc.
3. Durometer Demands (Hardness Shore A):
4.. Rubber Bellows Surface Demand
5. Working Environmment Demands
6. Rubber Bellows Flashing Demands etc.
(Note: Different 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.)
