[China Aluminum Network] The design and material selection of aluminum extrusion tools should refer to the following principles: Aluminum alloy extrusion tools generally include extrusion shafts, piercing pins, extrusion gaskets, extrusion dies, and extrusion cylinders. There are mold support, needle support and other components. The design of aluminum extrusion tools should not only be considered from the perspective of ensuring product quality, but also be reasonable in shape. When designing and selecting materials, it is also necessary to consider the service life, ease of use and maintenance, etc., and try to improve aluminum materials. Productivity, reduce aluminum product costs.
Aluminum extrusion tool material selection principle 1, at the working temperature, there is sufficient high temperature strength and hardness, high resistance to tempering and heat resistance.
2, there is enough toughness, low thermal expansion coefficient and good thermal conductivity.
3, in order to ensure the uniform mechanical properties of the entire section of the tool, to have good hardenability, good high temperature oxidation resistance.
4, good wear resistance and good thermal fatigue resistance, and has a good processing technology and low prices.
