Flexible Rubber Bellows
Flexible Rubber Bellows also known as Rubber Expansion Bellows, Custom Rubber Bellows, Silicone Rubber Bellows or Expansion Joints, Convoluted Rubber Bellows, or Rubber Dust Boots,which are usually used as sealing elements, and dust covers & dust boots in automotive industry, refrigeration industry and other areas.
Flexible Rubber Bellows have good performance, and is usually made by compression molding, extrusion mould or liquid silicone rubber injection molding.
For silicone rubber bellows that used as connector or sleeve and do not have strict requirement on the size tolerance, and do not have special material requirement, compression molding is enough. While if the structure of the bellow is complicated, and compression molding can not achieve the design structure and can not demold, then will need to choose liquid silicone injection molding to produce.
Liquid Silicone Injection Molded Silicone Bellows are much expensive than compression molded Custom Rubber Bellows.
Custom Molded Rubber Bellows Manufacturing Process
Flexible Rubber Bellows Functions:
Absorption of vibration;
According to different working environment, special properties material can meet different demands:
Silicone Rubber Bellows' Advantages:
Wide Working Temperature Range: -40℉ / -40℃—248℉ / 120℃
Excellent Elongation: Up to 600%
Good Tensile Strength
Good Aging Resistance
Oil & Grease Resistance
Chemical Resistance: Acid and alkali can hardly destroy the neoprene material.
Weather Resistance: Excellent performance in anti-ozone and anti-weather.
Better flame resistance: Neoprene is the best flame-resistance material among general rubbers. Neoprene cannot combust spontaneously. It burns when contacting flame, but puts out by itself once isolating the flame.
Rubebr Bellows can be customized into different shapes & constructions:
Tapered Rubber Bellows; Square Rubber Bellows; Straight Expansion Joints
