(Summary description) A, hardness and red hardness (thermal stability): Hardness is an important indicator of the mold. Under the mold to withstand the stress of the job role in maintaining the shape and size will not change quickly. Red means rigid mold under heat or high temperature, can stay organized and stable performance, with the ability of anti-softening.
B, wear: mold in their work to bear considerable stress and friction, requiring mold retains its shape and size unchanged, durable.
C, strength and toughness: Die bear the load and shock, vibration, and other complex stress at work. Requirements of the mold should have a sufficiently high strength and a certain toughness. High strength, easy to crack the mold; strength is too low, the mold easily collapse. Therefore, the required strength and toughness have a best fit, otherwise it will cause early failure of the mold.
D, but also consider the mold temperature strength, thermal fatigue, thermal resistance and abrasion resistance.
