OEM Aluminum Investment Casting Services with Pressurized Die Mold Making

OEM aluminum investment casting services integrated with pressurized die mold making represent the pinnacle of precision manufacturing for complex aluminum components. This advanced manufacturing approach combines the dimensional accuracy of investment casting with the efficiency of pressurized die technology, delivering superior aluminum parts with exceptional surface finish and mechanical properties for demanding industrial applications.

Material Excellence and Performance Characteristics

Our services utilize premium aluminum alloys including A356, A357, and 356-T6, specifically engineered for investment casting applications. These materials deliver outstanding performance characteristics:

• A356-T6: Tensile strength 234-262 MPa, yield strength 164-193 MPa, elongation 3-5%

• 356-T6: Tensile strength 255 MPa minimum, yield strength 207 MPa, Brinell hardness 75

• Excellent corrosion resistance with natural oxide layer formation

• Thermal conductivity: 120-160 W/m·K for efficient heat dissipation

• Low density (2.68 g/cm³) providing significant weight reduction advantages

The controlled silicon content (6.5-7.5%) in these alloys ensures optimal fluidity during the pressurized casting process while maintaining excellent mechanical properties after T6 heat treatment.
