Molded Corrugated Sleeves with Protective Bellows Boots and Flanged Circular Collar

When wall thickness at the bellows corrugation root is thinner than specified, the boot tears at the first corrugation under repeated flex cycles; corrugation root wall thickness and outer flange OD together determine whether the boot survives the full design cycle life in an automotive driveshaft or steering rack application. Changzhou Deying Molding (Changzhou, Jiangsu, established 2010) injection-moulds these rubber protective bellows boots with flanged circular collar and corrugated sleeve, with corrugation wall thickness, flange OD, and overall length confirmed using your drawing as reference at sample and verified in batch sampling. IATF16949 and ISO 9001 certification at Deying's 4,000 m² of workshop space Changzhou facility governs quality records for automotive driveline, battery module, and energy storage protective bellows applications.
