High precision aluminium casting machining

Advantages of Aluminium Casting Machining Service

1.High Precision and Dimensional Stability

Our aluminium casting machining service ensures high precision with tolerances as tight as ±0.005 in (±0.127 mm). The investment casting process used allows for minimal shrinkage and warping, maintaining dimensional stability throughout the machining process.

2.Excellent Surface Finish

The surface finish of our aluminium castings typically ranges from 125–250 µin (3.2–6.3 μm Ra) without the need for additional machining. This reduces the need for secondary finishing operations, saving time and cost.

3.Complex Geometries and Thin Walls

We can produce complex geometries and thin walls with intricate details. This is particularly beneficial for lightweight and high-performance components.

High Precision Aluminium Casting Machining Process

1.Pattern Creation

Wax or polymer patterns are created using injection molding or 3D printing. These patterns are then assembled into a wax tree for simultaneous casting.

2.Shell Building and Dewaxing

The wax patterns are coated with a ceramic slurry and fine refractory sand to build a heat-resistant ceramic shell. The wax is then melted out in an autoclave or furnace.

3.Metal Casting and Finishing

Molten aluminium is poured into the preheated ceramic mold. After cooling, the ceramic shell is removed, and the castings are cut from the tree. Post-processing includes grinding, machining, and surface finishing.

Applications of Aluminium Casting Machining Service

1.Automotive Industry

Ideal for turbocharger housings, transmission parts, and engine components that require high precision and lightweight materials.

2.Aerospace and Defense

Suitable for manufacturing lightweight components such as turbine blades and engine parts.

3.Industrial and Energy Sectors

Used for pump housings, valve bodies, and hydraulic components where durability and precision are crucial.
