Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses.
Casting is a method of pouring liquid metal into a mold cavity and waiting for it to cool and solidify to obtain a casting with a certain shape and performance.
The process mainly includes: making a casting mold (including patterns, cores, etc.), injecting liquid metal into the casting mold, cooling and solidifying the liquid metal in the casting mold, and finally taking out the casting and cleaning and other subsequent processing.
Casting has the following advantages:
1. Wide applicability: It can form parts of almost any shape, especially for parts with complex shapes and complex inner cavities.
2. High material utilization rate: For some materials that are difficult to process by other methods, casting can make better use of materials.
3. Relatively low cost: good economics in mass production.
Common casting methods include sand casting, metal mold casting, pressure casting, centrifugal casting, etc. Different casting methods are suitable for different occasions and requirements. Casting plays an extremely important role in many industrial fields such as machinery manufacturing, transportation, aerospace and so on.
