Magnesium Die Casting

Magnesium die casting at Sinbo Precision delivers exceptionally lightweight components with outstanding strength-to-weight ratio through hot chamber die casting technology. Our magnesium casting process injects molten magnesium alloy into precision steel molds under high pressure, producing parts that are 75% lighter than steel and 33% lighter than aluminum while maintaining excellent mechanical properties. Magnesium's low density and high specific strength make it ideal for weight-critical applications in automotive, aerospace, and electronics industries.

Our magnesium alloy portfolio includes AZ91D for general purpose applications with excellent castability and good mechanical properties, AM60B for enhanced ductility and impact resistance, AM50A for optimal ductility and toughness, and AE42 for high temperature applications. Each alloy formulation is optimized for specific properties including tensile strength, elongation at break, creep resistance, and thermal stability. Our experienced team provides expert guidance on alloy selection to ensure your magnesium die cast parts meet your exact requirements.

Every magnesium die cast part undergoes meticulous quality control including dimensional inspection, visual examination, and mechanical testing when required. We offer comprehensive secondary operations including CNC machining, surface finishing, painting, and assembly to provide complete, ready-to-use components. With our China factory and efficient logistics, you can receive your magnesium die cast parts quickly, ready for immediate use in your products. Our engineering team provides design for die casting guidance to optimize your parts for manufacturability and cost efficiency.
