aluminium extrusion is a process that involves to exert a certain pressure to push the hot, softened aluminium material at high temperature to squeeze through die continuously. Afterwards the workpieces are cooled down, harden and then be cut in required size. The process is usually used to produce heat sinks of various size and components of telecom equipment cavities.
mostly applicable to produce aluminium products or components with fix cross sectional profiles.
- capable of producing large components of complicate cross-sectional profile.
- the surface of the component is fine and smooth.
- the cost is relatively low comparing to the machining processes by removing material.
