The company is set to deliver its advanced Mechanical Face Seal portfolio to key markets across North America, Europe, and Asia-Pacific, addressing critical sealing challenges in construction, mining, agriculture, and renewable energy sectors.
As global infrastructure projects expand and mining operations push the limits of heavy machinery, the demand for high-end, reliable sealing components has reached an all-time high. At the forefront of this industrial demand is Huangshi Rviton Machinery Co., Ltd., a premier Chinese manufacturer specializing in the research, development, and production of heavy-duty mechanical face seals. Known globally as a pioneer in the industry, the company’s signature product line, the duo cone seal, is increasingly becoming the preferred choice for original equipment manufacturers (OEMs) and aftermarket distributors worldwide.
The global heavy equipment industry is undergoing a significant shift as construction, mining, and agricultural sectors demand longer operational lifespans and reduced maintenance downtime. At the forefront of this industrial evolution is Huangshi Rviton Machinery Co., Ltd. (professionally known as RVTON), a premier manufacturer specializing in the research, development, and production of heavy-duty duo cone seal technology.
(1) Precision casting type
This type of sealing ring is mostly made of high-chromium molybdenum alloy cast iron and is precision cast using paraffin shell molds. The hardness of the blank is (40-50) hrc, and the surface hardness of the finished product can reach (65-72) hrc. The roughness of the working surface is R, which ranges from 0.2 to 0.4um. Normally, the R value is 0.1. um, the service life can reach 4000~6000 hours. There are many manufacturing processes for this material, and many manufacturers use this method.
(2) Mechanical die-casting mold
This type of floating seal ring is made of alloy cast iron and is die-cast. The finished metallographic structure is relatively fine. However, the cost is slightly higher. The roughness R value of the working surface is 0.2-0.4um. The R value of the bright band is 0.09~0.15um. The service life is About 4000~6000h.
(3) Powder metallurgy hot satin type
This kind of sealing ring is mostly made of powder metallurgy through high-temperature hot forging. The working surface roughness R value is generally 0.4um, the finished product surface hardness (40~62) hrc, and the service life is about 2000~4000 hours.
(4) Thermal spray type.
The base body of the sealing ring is ordinary cast iron. It is thermally sprayed with 0.05~0.20mm high chromium molybdenum powder on the working surface and then grinded. The surface hardness reaches (55~65) hrc, and the service life can reach 4000~6000 hours. This type of process saves rare metals, but it is subject to equipment constraints, low productivity and high cost.
