Words from Satisfied Customers

“Fonyo used resin sand molding technology to replace traditional clay sand, reducing the surface roughness of the casting to Ra12.5μm, and almost no sand holes were visible after painting.”
John DoeProcurement Manager
“Cutting their cast iron parts reduced burrs by 70% and doubled the life of the castings”
Emily DavisEngineering Director
“Their ductile iron castings undergo three inoculation treatments, the graphite balls are highly round, and no obvious pores or slag inclusions can be seen on the cross-section.”
Michael JohnsonOperations Manager
“The cast iron parts of the outlet valves are free of rust after 1200 hours of salt spray test. The secret is the addition of 0.8% nickel and special shot blasting process.”
