Hebei Shida Seal Group is a leading supplier of high-quality molded rubber bellows and dust boots in China.
Molded rubber bellows and dust boots are flexible seals that protect mechanical structures from the environment while permitting a range of motion. They are used in industrial, transportation, and many other applications as a protective covering against dust, water, oil, grease, chemicals, and environmental elements such as mud, splatter, and snow. Rubber bellows can also reduce noise, resist shock and vibration, and withstand sunlight and ozone while remaining flexible at changing temperatures.

Molded Rubber Bellows – Methods of Molding:
- Compression molding — The most basic form of molding, compression molding is exactly what it sounds like: pressing two sides of a mold together and forming rubber parts through it. Before compression molding begins, a “pre-form” in the basic shape of the final product are made. These pre-forms have extra rubber, ensuring that the cavity is filled entirely and there are no flaws in the end part.
- Rubber injection molding — This involves rapidly injecting an exact amount of rubber into a closed, heated mold. Pressure keeps the mold closed. There are some economic advantages to this type of molding, particularly a shorter molding cycle, lower unit cost, and little scrap or waste.
Molded rubber bellows are available in several rubber materials including:
- Ethylene-Propylene (EPDM, EP)
- Nitrile Rubber (NBR)
- Natural Rubber (NR)
- Silicone Rubber (VMQ)
