Shailesh International pioneered the development, manufacturing and application of cost-effective, high-performance valve seat inserts. Our products have become the preferred choice for marine, diesel and gasoline engines.
Alloy selection includes traditional wear resistant to unique proprietary materials designed to match the specific application of the valve seat insert needed. Our wide range of valve seat inserts are made from nickel, chrome, cobalt and iron based alloys that display superior wear and heat resistant properties. The design of the surface and angles of valve seat insert depends on engine criteria like engine application, fuel type, combustion temperature and pressure, seating velocity, material selection and seating stress.
We have complete in-house capabilities for development, metallurgy, casting, tooling and testing. The casting, which is the most important and typical factor in the manufacturing of the valve seat inserts, is done on latest high frequency induction melting furnace. These are individually and centrifugally casted, as the case may be, under the strict supervision of qualified metallurgists.
