Aluminum Casting
High integrity aluminum die casting, sand casting, and permanent mold casting engineered for lightweight strength, high thermal conductivity, and complex thin walled structural parts.
Choosing the Right Aluminum Casting Process for Your Part
Aluminum casting covers several distinct processes, high pressure die casting for thin walled, high volume parts, low pressure die casting for structural components under cyclic load, permanent mold casting for parts requiring T6 heat treatment, and sand casting for large or low volume structural shapes, each suited to a different combination of geometry, volume, and mechanical performance.

Why Choose Cast Aluminum for Structural and Thermal Parts
Ultra Lightweight Structural Strength
Reduces overall assembly weight by up to 65% compared to cast iron while maintaining exceptional structural rigidity and load rating.
Superior Thermal and Electrical Dissipation
High thermal conductivity up to 160 W/mK provides rapid heat dissipation for EV motor enclosures, battery trays, and LED heat sinks.
Complex Thin Walled Geometries
Casts intricate wall sections down to 1.2mm with internal strengthening ribs, minimizing weight without compromising load rating.
Excellent Surface Finishing and Anodizing
Highly responsive to Type II/III hard anodizing, alodine chromate conversion, powder coating, and durable electrophoretic deposition finishing.
Aluminum Alloy Classification for Casting
Materials
A356/AlSi7Mg (High Strength Structural Alloy)
Primary permanent mold and sand casting alloy optimized for T6 heat treatment, delivering high elongation, impact toughness, and structural strength.
A380/ADC12 (High Fluidity Die Casting Alloys)
Premier high pressure die casting alloys offering excellent castability, dimensional stability, and tight tolerance for electronic housings.
AlSi10Mg and Custom Thermal Alloys
Formulated for superior thermal management, ideal for high wattage power electronics enclosures, heat exchangers, and cooling plates.
Forming Methods
High Pressure Die Casting (HPDC)
Automated high speed production method ideal for thin walled, high volume aluminum components with smooth surface finish.
Low Pressure Die Casting (LPDC)

Permanent Mold (Gravity) Casting
Produces dense, pore free aluminum castings highly responsive to T6 solution and age heat treatment for structural robotics.
Green Sand and Resin Sand Casting
Cost effective method for prototyping and large scale structural aluminum castings requiring minimal tooling investment.
Aluminum Casting Production Workflow
Four controlled stages ensuring gas degassing, T6 heat treatment, and precision CNC finishing.
Mold Flow Thermal Simulation and Alloy Selection
CAD models undergo thermal mold flow analysis to optimize gating systems. Spectrometrically verified aluminum ingots are prepped for melting.
Die Tooling and Ceramic Mold Prep
Hardened steel dies (H13) or ceramic sand molds are pressed and preheated to exact thermal equilibrium.
Melt Degassing and Automated Injection
Molten aluminum is degassed with argon rotary impellers to remove hydrogen, followed by automated high pressure or gravity pouring.
T6 Heat Treatment and CNC Finishing
Castings undergo T6 solution heat treatment and artificial aging, shot blasting, 5 axis CNC post machining, and anodizing.
Industrial Applications
