Precision aluminum alloy casting

Aluminum alloy casting, with precision CNC machining, powder coating or anodizing finishing

Aluminium Cast refers to the process of pouring molten aluminium into a mold and allowing it to cool and solidify into the desired shape. This method is widely used in various industries due to aluminium's unique properties, such as its lightweight, corrosion resistance, and strength-to-weight ratio. The applications of aluminium castings include automotive parts, aerospace components, and construction materials, among others

Applications of Aluminium Cast
Automotive Industry: Used for engine parts, body panels, and structural elements, aluminium castings help in reducing the overall weight of the vehicle and improving fuel efficiency.
Aerospace Industry: Employed in the production of turbine blades, compressor disks, and other high-precision components that require lightweight and strong materials.
Construction Industry: Used in the creation of beams, columns, and decorative elements such as statues and fountains, benefiting from aluminium's durability and aesthetic appeal.

1.Temperature control
Pouring temperature:
Silicon aluminum alloy (such as ADC12): simple structural components at 610-630 ° C, complex components at 644-680 ° C 12.
Alloys with poor fluidity require an increase in temperature (e.g. A380 alloy can reach 720 ° C).
Mold temperature:
Aluminum alloy molds are recommended to be heated between 200-280 ° C, with higher temperatures required for thin-walled/complex parts.
2.Injection parameters
Injection speed:
Slow stage 0.1-0.5m/s (exhaust), fast stage 2-6m/s (filling) 45.
Thin walled components require a speed of ≥ 4m/s, while thick walled components can reduce the speed by 5.
Pressure ratio:
Thin walled components have a pressure range of 80-120MPa, while thick walled components can reduce pressure but require an increase of 5% in boost pressure.
3.Time parameter
Filling time: 0.01-0.1 seconds, extended by 3 seconds when the alloy temperature is high or the mold heat dissipation is fast.
Pressure holding time: ≥ 2 seconds, with an extension of 0.5 seconds for every 1mm increase in thick walled components.
4.Material and Composition Standards
ADC12 (Japanese standard, silicon content 10.5-12%), A380 (American standard, good fluidity) 7.
Domestic Y102/Y112 are suitable for different strength requirements.
Composition requirements:
Aluminum content ≥ 90%, silicon 7-12%, copper/magnesium adjusted by grade 8.

Casting and die-casting are metal forming processes that use molten metal injection. While casting offers broader production scope for large-scale, complex metal components with average dimensional accuracy, die-casting employs high-pressure injection through precision molds. This method excels in mass-producing parts featuring thin walls, intricate geometries, smooth surfaces, and exact dimensions – though it requires significantly higher mold costs due to its high-efficiency nature.

Casting is mainly used to produce large and complex structural parts with high requirements for strength and durability, but relatively loose dimensional accuracy, such as heavy machinery, automobile industry, infrastructure.
Die casting focuses on the production of thin wall, complex shape, precision size and smooth surface small and medium-sized parts, suitable for mass production, typical fields include automotive industry, 3C electronics, daily hardware.
