Cast iron is an iron-carbon alloy renowned for its excellent castability, wear resistance, and vibration damping. It is widely used to produce engine flywheels, exhaust manifolds, pistons, and machinery bases. Common types include gray iron, known for damping and machinability, and ductile iron, such as Ductile Iron 450, which offers higher strength and toughness. The process involves precision sand casting, melting, pouring, controlled cooling, machining, and surface treatment. High-quality cast iron parts deliver durability, thermal stability, and cost-effectiveness, making them essential across commercial vehicles, construction equipment, and industrial machinery. Choosing a reliable foundry ensures consistent quality, accurate dimensions, and long service life.

The marine exhaust manifold is an essential high-temperature component for marine diesel engines, working under severe conditions of high temperature, vibration and salty humid marine atmosphere. Our manifolds are cast from Si‑Mo ductile iron featuring excellent thermal fatigue and oxidation resistance. We offer two tooling solutions: one‑time tooling for sample orders and permanent tooling for mass production. Each casting goes through stress-relief heat treatment, CNC machining and strict air tightness inspection. Customization is available according to samples, 2D drawings or 3D CAD files. We support small-batch sample orders with preferential prices for larger follow-up orders, providing dependable replacement spare parts for ship engines.

About aftermarket exhaust manifolds for Mitsubishi Fuso trucks. Made of ductile cast iron, they offer excellent heat and crack resistance. Optimized runners cut exhaust backpressure to preserve engine power. Manufactured to OEM standards with leak testing, the manifolds fit directly without modification. They are a cost-effective replacement for Fuso Canter and Super Great models, with custom casting available for global buyers.
