Customized Wear Resistance EPDM Rubber Expansion Joint Covers
Rubber Expansion Joint Covers 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 Expansion Joint Covers are designed as a cover mainly to protect against dust, water, oil, grease ,acids, bleaches, spatter or other environment elements.
Rubber Expansion Joint Covers-Main Structions and Shapes
Rubber Expansion Joint Covers-Materials Ddoption
Rubber Expansion Joint Covers-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 Expansion Joint Covers 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.
(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)
