Material & Construction
Made from 356-T6 aluminum, the housing provides a strong balance of rigidity and corrosion resistance. The gravity-cast structure offers solid base geometry, while precision machining refines all sealing surfaces, bolt locations, and mating geometries.
This approach results in a gravity cast aluminum housing with enhanced accuracy and long-term durability.
Machining & Quality Control
After casting, the entire part is processed through controlled CNC machining, allowing:
Clean, accurate flange surfaces
Tight tolerance across bolt circles
True concentricity of internal diameters
Improved repeatability for assembly fit
This makes the housing suitable for demanding applications where precision aluminum components are required.
Applications
The component is commonly used in:
Pump housings
Compressor assemblies
Valve bodies
Industrial pneumatic systems
Structural frames and mechanical support units
Its combination of pressure resistance, controlled wall thickness, and refined machined structure makes it ideal for both heavy-duty and general industrial use.
FAQ
-CNC Machined Aluminum Casting Housing
Q: What material is this housing made from?
A: The part is produced from Aluminum Alloy 356-T6, certified per QQ-A-601. This alloy offers excellent castability, stable mechanical strength, and reliable performance after heat treatment.
Q: What casting process is used for this component?
A: The housing is manufactured through a gravity casting process, followed by CNC machining to achieve accurate sealing surfaces, bolt patterns, and dimensional tolerances.
