introduction：1.Raceway sound Raceway sound is due to bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]When rotating, the rolling element rolls in the raceway and generates a smooth and continuous noise，It attracts attention only when its sound pressure level or tone is extremely high。In fact, the sound energy stimulated by raceway sound is limited，As in normal circumstances，Of high quality6

introduction： Some molds are in a state of repeated heating and cooling during work，The surface of the cavity is strained、Pressure changes the role of stress，Causes surface cracking and spalling，Increase friction，Retarding plastic deformation，Reduced dimensional accuracy，Resulting in mold failure。Hot and cold fatigue is one of the main failure forms of hot working die，This kind of mold should have high resistance to cold and heat fatigue。 6．Corrosion resistance Some molds such as plastic molds are at work，Due to the presence of chlorine in plastics、fluorine，Decompose and precipitate after being heatedHCI、HFEqually aggressive gas，Erosion of the mold cavity
