      Choose right compression of die spring or will distortion and reduce service life.   Can’t have gap between upper plate and die spring or will distortion and rupture. When free length of die spring is 4 times to outer diameter ,please use guide rod shield to protect service life. Can't use it for anything except compression . Please use it on the mould. When the lower plate parallelism is not well, high stress will happen and cause transformation and rupture . It must be have some preloading when put die spring on the mould . preventing mould Bear impact load and cause fatigue damage.        Our equipment     Our certificate        Our customers
