Aluminum Extrusion tools typically include extrusion axis, piercing needle, squeeze gaskets, extrusion molding, extrusion tube, in addition to mold support, needle bearing and some other parts. Aluminum extrusion tool is designed not only to be considered from the point of view of product quality assurance, it is reasonable shape, but also in the design and selection of materials, you should also consider their life, whether it easy to use and maintain, as far as possible to improve the aluminum production efficiency and reduce the cost of aluminum products.
Principles aluminum extrusion tools and materials selection
1, at the working temperature, there is sufficient high temperature strength and hardness, high tempering resistance and heat resistance.
2, a sufficient toughness, low thermal expansion coefficient and good thermal conductivity.
3, in order to ensure uniformity of the mechanical properties of the tool the entire cross-section, have a good hardenability, good high temperature oxidation resistance.
4, good wear resistance and good thermal fatigue resistance, and good processing technology and low prices.
