die-casting is injection molding casting by metal oil pressure, the pressure
can up to 3000 tons.||Pour

CNC and other secondary is expensive, but it also has perfect effect.||Comparison
with extrusion collocation CNC, die-casting is more cheap, but die-casting only
fit with high-fluidity of alloy.||Belong
hi-difficulty but cost more cheap engineering method.|
Surface finish usually directly affects the texture of the finished product, the degree of detail has a considerable difference.
The higher purity of the aluminum material, the better the cooling effect of the finished product, especially in the electronic parts of the temperature has a precise control.
The extrusion with CNC and other secondary processing are most expensive of, but the accuracy and precision are perfect, product assembly completely closely, good quality is the need to pay the cost of pursuing.
Aluminum ingot → Aluminum extrusion → CNC machining → sand blasting → anodize .
