The differences between CNC intercooler tanks and cast intercooler tanks

1.Manufacturing Process

Cast version: The casting process is employed. Metal materials are heated to a molten state and then poured into a pre-made mold. After cooling and solidification, the desired end cap shape is formed.

CNC version: Computer Numerical Control (CNC) technology is utilized. The process involves using a programmed machine tool to cut and shape the metal material.

2. Material Selection

Cast version: Typically, materials such as casting aluminum alloy are used. These materials have good casting properties that meet the requirements of the casting process, but their mechanical properties are relatively poor.

CNC version: High-strength aluminum alloys, such as 6061 aluminum alloy, are generally used. These materials have high strength and good corrosion resistance, which meet the requirements of CNC machining and also ensure the performance of the tank.

3. Performance Characteristics

Cast version: Due to the limitations of the manufacturing process, there may be internal defects such as gas porosity and sand inclusions. These defects can affect the strength and sealing performance of the tank. Additionally, the surface roughness of the cast tank is relatively high, which may create some resistance to the flow of coolant.

CNC version: The surface is smooth, which can reduce the resistance to coolant flow and improve cooling efficiency. The high precision of its internal structure can better meet the engine's requirements for coolant flow and pressure, thereby enhancing the performance of the engine.

4. Cost and Price

Cast version: The manufacturing cost is relatively low and it is suitable for mass production. Its price is usually more affordable, giving it a certain price advantage in the market.

CNC Intercooler End Cap: Due to its high machining accuracy, relatively lower production efficiency, and the need for high-precision CNC equipment, the manufacturing cost is higher.
