Product Description
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.
Rubber Bellows Main Structions and Shapes
Straight Convolution Rubber Bellows Spiral Convolution Rubber Bellows
Concentric Rubber Bellows Tapered Rubber Bellows
Metal+Rubber Overmold Bellows Rubber Bellows with Clamping, Hole & Lock
Rubber Bellows Materials adoption
Rubber Bellows Design Guide
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
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.
