Our Segmented Step-Vulcanization Technology enables the production of extra-large and custom-diameter O-rings without the need for oversized molds or large-tonnage hydraulic presses.
The O-ring is formed, positioned, and hot-vulcanized section by section using compact, precision tooling. Each section is permanently bonded through controlled vulcanization, creating a continuous, high-strength sealing loop with consistent dimensions and accurately positioned holes.
This technology significantly reduces tooling and equipment costs while providing a reliable solution for large storage tank flanges, pressure vessels, industrial doors, rail transit, wind power, heavy machinery, and marine applications.
Are you burdened by the sky-high costs of giant molds and massive hydraulic presses for extra-large O-rings, or frequent joint failures caused by traditional cold-gluing? Our advanced Segmented/Step-Vulcanization Technology breaks through these traditional manufacturing limits, offering a high-strength, high-cost-performance revolutionary solution.
Technical Highlight: Small Mold, Massive O-Rings
As shown in the production images, this innovative process completely eliminates the need for massive, full-circle single-piece molds and giant machinery:
This process is engineered for custom-sized, heavy-duty, and high-reliability sealing in demanding industrial environments:
