Aluminium Alloy CNC Machining Product
Material: Aluminium Alloy Process: Die Casting + CNC Machining Weight: 4.62 kg Application: Truck Spare Parts
China CNC machining of Aluminium alloy with one stop solution from casting, heat treatment, surface treatment and precision machining.
Description
Aluminium alloy is usually cast by gravity casting (die mold), low pressure casting and high pressure die casting. The CNC machining is also needed if the fine finish and high precision accuracy are needed.
