PGC Engine Parts manufactures and exports precision-engineered cylinder liners and sleeves for automotive, commercial, agricultural, marine, industrial, and heavy-duty engine applications. Our products are designed to provide a reliable cylinder running surface with excellent resistance to wear, friction, thermal stress, combustion pressure, and continuous piston movement.
Manufactured from carefully selected grey cast iron and alloy cast iron, our cylinder liners and sleeves are produced using controlled casting, heat treatment, precision machining, honing, and finishing processes. Accurate bore geometry, wall thickness, concentricity, hardness, and surface finish are maintained to support proper piston and ring operation, effective heat transfer, and long-term dimensional stability.
PGC Engine Parts can manufacture products according to OEM specifications, customer drawings, samples, engine models, part numbers, and customized technical requirements.

Material Options
Grey Cast Iron
Grey cast iron is widely used for air-cooled cylinder blocks because of its good machinability, vibration-damping characteristics, wear resistance, thermal conductivity, and dimensional stability.
Alloy Cast Iron
Alloy cast iron can be selected for applications requiring enhanced hardness, strength, wear resistance, and thermal stability. Alloying elements such as chromium, nickel, molybdenum, copper, and vanadium may be incorporated depending on the required material properties.
Material selection can be specified according to OEM requirements, engine application, customer drawings, technical specifications, and applicable standards
Applicable Standards
Air-cooled cylinder blocks can be manufactured according to customer-specified material standards, including:
ASTM: A48 Class 30/35/40 and applicable grades
DIN: GG20, GG25, GG30 and applicable grades
JIS: FC250, FC300
IS: IS 210 – FG 220, FG 260, FG 300
EN: EN-GJL-250, EN-GJL-300
The appropriate material grade is selected based on the required chemical composition, mechanical properties, hardness, microstructure, and engine application.
Manufacturing & Quality
Our manufacturing process may include pattern making, casting, heat treatment, rough machining, CNC machining, boring, honing, grinding, and finishing operations. Cooling fins, cylinder bores, mounting holes, gasket surfaces, and other critical features are manufactured according to the required engineering specifications.
Quality inspection may include bore diameter, bore roundness, dimensional tolerances, wall thickness, cooling-fin dimensions, mounting dimensions, surface finish, hardness, material composition, microstructure, and overall dimensional conformity.
PGC Engine Parts also supports custom manufacturing based on OEM part numbers, technical drawings, physical samples, engine models, and specific material or machining requirements.
