Nodular Cast Iron Crankshaft Casting for Automotive Diesel Gasoline Engine

Made of high-grade ductile iron (QT600-3/QT700-2), with excellent tensile strength and fatigue resistance, withstands long-term high-speed cyclic load of engine operation.

Produced by a mature sand casting process with stress relief annealing treatment, eliminates internal casting stress, ensures stable structure, and prevents deformation during long-term use.

Integral one-piece casting structure, without welding seams, effectively avoids fracture risk under high loads and guarantees reliable engine power output.

Precise crank throw and counterweight design, good basic dynamic balance performance, reduces engine vibration during operation, and improve running smoothness.

Standard delivery in the as-cast blank state, with optional CNC precision machining and dynamic balance treatment, is available to meet finished product assembly requirements.

Strict full-process quality control and non-destructive testing for key stress positions eliminate casting defects such as pores and cracks, ensuring stable batch quality.

Strong customization capability, produces crankshafts of different cylinder numbers, sizes, and materials strictly according to customer drawings, and adapts to various engine models.

Wide application range, widely used as the core power transmission component for automotive engines, diesel engines, gasoline engines, and other internal combustion engines.
