耐蝕性有些模具如塑料模在工作時,由于塑料中存在氯、氟等元素,受熱后分解析出HCI、HF等強侵蝕性氣體,侵蝕模具型腔表面,加大其表面粗糙度,加劇磨損失效。Corrosion resistance of some moulds, such as plastic moulds, when working, due to the presence of chlorine, fluorine and other elements in the plastic, HCI, HF and other strong corrosive gases are decomposed after heating, which erode the surface of the mould cavity, increase its surface roughness and aggravate wear failure.
高溫性能當模具的工作溫度較高進,會使硬度和強度下降,導致模具早期磨損或產生塑性變形而失效。因此,模具材料應具有較高的抗回火穩定性,以保證模具在工作溫度下,具有較高的硬度和強度。When the working temperature of the die is higher, the hardness and strength will decrease, leading to early wear or plastic deformation of the die and failure. Therefore, the die material should have high temper resistance stability to ensure that the die has high hardness and strength at working temperature.
耐冷熱疲勞性能有些模具在工作過程中處于反復加熱和冷卻的狀態,使型腔表面受拉、壓力變應力的作用,引起表面龜裂和剝落,增大摩擦力,阻礙塑性變形,降低了尺寸精度,從而導致模具失效。The cold and thermal fatigue resistance of some dies is in the state of repeated heating and cooling in the working process, which makes the surface of the cavity subject to tension and pressure variable stress, causes surface cracking and peeling, increases friction, hinders plastic deformation and reduces dimensional accuracy, thus leading to die failure.
