Custom Cast Iron Cylinder Body Casting Services

The cylinder body serves as the foundational heart of any piston-based machinery, where dimensional stability, thermal management, and long-term durability are non-negotiable. Our Custom Cast Iron Cylinder Body Casting Services specialize in producing these critical components with uncompromising quality. We engineer cylinder bodies that deliver superior performance for hydraulic and pneumatic systems, compressors, and industrial engines, ensuring reliable operation under sustained pressure and mechanical stress.

Engineered Cast Iron Alloys for Demanding Applications
We select specific grades of cast iron to match the operational demands of your cylinder body:

• Gray Cast Iron (Grade 250/300): The industry standard for its excellent damping capacity and low cost, effectively absorbing vibrations from piston movement. Its self-lubricating graphite flakes provide good wear resistance, ideal for general industrial applications.

• Ductile Iron (Grade 400-18/500-7): Offers a superior combination of high tensile strength, impact resistance, and toughness. Its spheroidal graphite structure makes it the material of choice for high-pressure hydraulic cylinders and applications subject to shock loads, providing a safety margin against fracture.

• Compacted Graphite Iron (CGI): An advanced material that provides a perfect balance between the damping of gray iron and the strength/ductility of ductile iron. It is increasingly specified for high-performance engine blocks and cylinder liners.

Precision-Controlled Sand Casting Process
Our manufacturing relies on advanced sand casting techniques to ensure the integrity and accuracy of complex cylinder bodies.

• Furan No-Bake Sand Molding: This state-of-the-art molding process uses chemically-bonded sand to create molds with exceptional dimensional stability and a superior surface finish. It is ideal for producing the precise bores, ports, and internal passages of a cylinder body.

• Process Simulation: We utilize casting simulation software to predict and prevent potential defects like shrinkage porosity, ensuring a sound and dense microstructure, especially in critical wall sections.

• Chill Technology: For applications requiring a hard, wear-resistant bore surface, we strategically implement metal chills in the mold. This accelerates cooling to create a refined, pearlitic microstructure at the bore, enhancing durability without additional machining.

Integrated Machining and Quality Assurance
As a one-stop service, we deliver fully finished components. Our in-house CNC machining centers perform precision boring, honing, and facing of critical surfaces, including the main bore, end ports, and mounting features. Each cylinder body undergoes rigorous pressure testing to validate its integrity at operating pressures, guaranteeing leak-free performance.

Proven Applications Across Industries
Our custom-cast cylinder bodies are essential in:

• Industrial Hydraulics: Presses, plastic injection molding machines, and machine tool actuators.

• Pneumatic Systems: High-cycle automation equipment and air compressors.

• Power Generation: Cylinder bodies for gas and diesel engines.

• Marine and Offshore: Steering gear and winch actuators.
