Squeeze Casting vs Aluminum Extrusion

Squeeze Casted

There are several distinct benefits of Squeeze Casting over Aluminum Extrusion:

Material Properties

Squeeze casting enables the production of components with superior mechanical properties compared to aluminum extrusion. The application of pressure during solidification in squeeze casting reduces porosity and enhances material density, resulting in parts with improved strength, ductility, and fatigue resistance.

Complexity and Design Flexibility

Squeeze casting allows for the production of intricate and complex-shaped components with thinner walls and finer details compared to aluminum extrusion. This versatility in design enables manufacturers to create parts with more sophisticated geometries and functionalities, expanding the range of potential applications.

Dimensional Accuracy and Tight Tolerances

Squeeze casting offers greater dimensional accuracy and tighter tolerances than aluminum extrusion. The precise control over the casting process, including pressure application and cooling rates, ensures consistent part dimensions and minimal variability, making it ideal for applications where tight tolerances are critical.

Surface Finish

Squeeze casting typically yields components with smoother surface finishes compared to aluminum extrusion. The combination of pressure application and rapid solidification results in parts with minimal surface defects and improved surface aesthetics, reducing the need for additional finishing operations.

Material Efficiency and Waste Reduction

Squeeze casting minimizes material waste compared to aluminum extrusion. The near-net shape capability of squeeze casting allows for the production of parts with minimal machining or material removal, leading to higher material utilization rates and reduced scrap generation.


While squeeze casting may involve higher initial tooling and setup costs than aluminum extrusion, it can offer long-term cost savings through improved material efficiency, reduced machining requirements, and enhanced part performance. The ability to produce high-quality, near-net shape components with fewer secondary operations can contribute to overall cost-effectiveness over the product lifecycle.

In Summation

While both squeeze casting and aluminum extrusion are valuable manufacturing processes for producing aluminum components, squeeze casting offers distinct advantages in terms of material properties, design flexibility, dimensional accuracy, surface finish, material efficiency, and cost-effectiveness, making it a preferred choice for certain applications requiring high-performance and precision-engineered parts.
