Federal-Mogul Corporation is establishing a joint venture to manufacture large-bore piston rings in Changsha, China, mainly for industrial-engine manufacturers there and in other Asian markets. The new JV, Federal-Mogul Zhengsheng (Changsha) Piston Ring Co. Ltd., will supply high-technology piston rings primarily for four-stroke industrial engines used in commercial shipping, railroad, energy and off-road industries.
In reciprocating engines (diesel, gasoline, or other), a piston ring is a split device inserted in a groove on a piston’s outer diameter, to seal the chamber, transfer heat, and regulate coolant consumption. Federal-Mogul notes that high-quality piston rings are critical to efficient operation of high-demand industrial engines with multi-year duty cycles. It engineers and supplies piston rings and other critical components to industrial engine manufacturers that include MAN, Wartsila, Doosan, Mitsubishi, Caterpillar, and MTU.
For large-bore engines, Federal-Mogul’s piston rings are produced in cast ductile iron or chromium steel, and coated with chromium, CKS, plasma coatings, physical vapor deposition (PVD), or twin layer coatings. It explained that material properties, coating performance, and ring design are customized to maximize service life and minimize maintenance.
The rings are marketed for distribution under its Goetze and Daros brands.
Michigan-based Federal-Mogul did not indicate the value of its investment, but it noted it would be its second large-bore ring plant in China, and would expand its current product range of 2-stroke and 4-stroke industrial rings. The company has multiple product lines for automotive, commercial vehicle, and industrial and heavy-duty engines (marine, rail, aerospace, power generation).
