Hongjie supplies automotive rubber seals for door, trunk, hood, and window sealing from a factory-direct library of 3,500+ existing tools — matching an OEM drawing against that library before cutting new steel, which shortens the quote-to-sample path.
Hongjie has manufactured sealing components since 2001 from an 11,000 m² Shenzhen facility with roughly 150 staff, IATF 16949:2016-certified. Automotive rubber seals for door and trunk applications draw on the existing tooling library first; a new custom mold is only cut when no match exists.
Profiles designed to seal doors and trunk openings against water, dust, noise and air leakage during repeated opening and closing.
Includes glass-run channels, flocked-lip window profiles and sunroof drain seals. These components are typically extruded and cut to the required length.
Used around body-panel gaps, cowl areas and other exterior joints to reduce water ingress, vibration and wind noise
Sealing profiles for engine-bay and underbody applications, where resistance to heat, oil, moisture, dirt and road exposure is required.
±0.02–0.10mm on molded critical dimensions; ±0.10–0.25mm on extruded profiles
40–80 Shore A
smooth, flocked, textured
functional prototypes in 3–5 business days; MOQ and tooling lead time confirmed at quote
3,500+ existing tools, 50M+ precision-inspected parts delivered annually to global Tier-1 suppliers, and export to 45+ countries back every automotive seal program.
