OEM Aluminum Casting Services for RC Model Plane Sand and Gravity Casting Techniques

As a specialized OEM manufacturer, we provide precision aluminum casting services specifically engineered for RC model aircraft applications. Our expertise in both sand casting and gravity casting techniques enables us to deliver lightweight, high-strength components that meet the exacting requirements of radio control aviation enthusiasts and manufacturers worldwide.

Material Excellence and Performance Characteristics

We utilize specialized aluminum alloys chosen for their optimal strength-to-weight ratios and casting performance. Our A356-T6 aluminum alloy offers exceptional mechanical properties with tensile strength of 234 MPa and yield strength of 193 MPa after heat treatment, providing the perfect balance between weight savings and structural integrity. For applications requiring superior fluidity and pressure tightness, we employ A413 aluminum alloy with excellent castability and minimal shrinkage characteristics. These materials demonstrate:

• Outstanding strength-to-weight ratios for enhanced flight performance

• Excellent corrosion resistance ensuring long-term durability

• Superior machinability for precision post-casting modifications

• Good thermal conductivity for efficient heat dissipation

• Consistent dimensional stability across temperature variations

Advanced Casting Manufacturing Process
