Mainstream: Micro-alloyed ductile iron (52%), alloy steel (31%), tensile strength ≥ 900 MPa.

High-end: Powder metallurgy, carburizing and quenching steel (27%), suitable for hybrid and high-load conditions.

Surface Treatment: Laser quenching, PVD/DLC coating, friction coefficient reduced to below 0.02, lifespan increased by 5 times.

Prestressed camshaft: Steel pipe + cam plate, weight reduction by 30% - 40%, assembly rate for passenger cars exceeds 65%; Kebirite in Ningbo and others have achieved domestic substitution, with equipment cost being 1/10 of the imported version.

Hollow camshaft: Penetration in commercial vehicles accelerates, with built-in oil circuit cooling and lubrication, reducing fuel consumption by 0.3 - 0.5 liters per 100 kilometers.

VVT / Integrated module: Compatible with hybrid and high thermal efficiency (≥ 42%) engines, with precision requirements of Ra ≤ 0.4 μm and dynamic balance ≤ 5 g·cm.

Precision process: Hydraulic bulging cycle is 15 seconds per piece, connection torque ≥ 120 N·m; CNC grinding machine + online inspection, one-time qualification rate ≥ 98%.

Digital twin: R&D cycle is shortened by 40%, trial production cost is reduced by 25%, and it is compatible with multi-variety flexible production.
