Engine Cylinder Block

This series of castings including engine blocks, cylinder heads and main bodies are manufactured by combining well-established casting processes with advanced 3D sand-mold printing technology. They serve as core load-bearing and power components for internal-combustion engines, construction machinery, generator sets and other equipment. Made of high-quality cast iron and alloy cast iron, these parts feature dense and homogeneous microstructure, delivering high strength, high rigidity, wear resistance, thermal-fatigue resistance and excellent sealing performance for stable long-term operation under high-temperature, high-pressure and alternating-load working conditions.

As the main framework of an engine, the cylinder block adopts a well-optimized structural layout. Its oil passages, water galleries and air passages are integrally formed with high dimensional accuracy and tightly controlled geometric tolerances, effectively guaranteeing assembly precision and operational stability of the complete machine. The cylinder head is precisely matched with combustion chambers and valve-trains. With outstanding sealing and heat-dissipation performance, it minimizes gas, oil and water leakage and improves power output efficiency. Various main-body castings are custom-produced for different models covering a wide range of specifications to suit passenger vehicles, commercial vehicles, agricultural machinery, construction machinery and other application scenarios.

The whole workflow, from product design and sand-mold fabrication to melting-pouring and precision post-machining, is performed in strict compliance with industrial quality standards. Finished products boast smooth surfaces and are free from internal defects such as porosity, shrinkage porosity and slag inclusions. We support single-piece customization, prototype trial production and bulk supply. Equipped with rapid prototyping technology, lead-time can be greatly shortened. With reliable quality and consistent performance, our castings provide robust core-component support for diverse power equipment.
