In heavy-duty diesel engine applications, the flywheel serves as the critical link between engine power and drivetrain load. Our Solid Tooth Cast Flywheel, manufactured using high-quality grey cast iron, represents a pinnacle of reliability and performance for commercial vehicles, industrial machinery, and agricultural equipment. This product embodies our commitment to delivering casting services that meet the most demanding operational requirements.
Premium Material Selection: Grey Cast Iron GG25/GG30
We utilize high-grade grey cast iron (typically GG25 or GG30 specification) for its exceptional functional properties in diesel engine applications. This material provides outstanding compressive strength and superior vibration-damping capabilities - crucial for smoothing out power pulses from diesel combustion cycles. The flake graphite microstructure naturally provides lubricity while offering excellent wear resistance against starter motor engagement. Its thermal stability maintains dimensional integrity under fluctuating operating temperatures, preventing warpage that could compromise clutch performance.
Advanced Manufacturing Process
Our production begins with precision pattern making for accurate tooth geometry and mounting specifications. Using resin sand molding technology, we create stable molds that produce castings with excellent surface finish and dimensional consistency. The integrated solid tooth design is cast as a single piece, eliminating potential failure points from welded ring gear installations. Post-casting, each flywheel undergoes precision machining on CNC equipment to ensure perfect flatness of the friction surface, accurate pilot bore dimensions, and true running faces. The final dynamic balancing process brings each unit to within strict tolerance limits, ensuring vibration-free operation across the entire operational RPM range.
Performance Characteristics and Applications
These flywheels deliver reliable performance through:
High thermal capacity resisting heat checking
