Aluminum profile extrusion die performance requirements

【China Aluminum Industry Network】 A, hardness and red hardness (heat stability): Hardness is an important indicator of the mold. Under the effect of stress during operation, the mold will not change rapidly in shape and size. Red hardness means that the mold works under heat or high temperature, can maintain the stability of the organization and performance, and has the ability to resist softening.

B. Abrasion Resistance: The die must bear considerable compressive stress and friction during work. The die must be able to maintain its shape and size, and be durable.

C. Strength and Toughness: The molds are subjected to loads during work, as well as complex stresses such as impact and vibration. It is required that the mold should have a sufficiently high strength and a certain toughness. The strength is too high, the mold is easy to crack; the strength is too low, the mold is easy to collapse. Therefore, there is a better match between strength and toughness, otherwise it will cause early failure of the mold.

D. Also consider the high temperature strength, thermal fatigue, thermal conductivity, and wear resistance of the mold.
