1, due to the butterfly spring elasticity did not hub tight, so that the spindle shaking and lead to ring die cracking, this situation is generally more common and the solution is relatively simple and common, the general solution is to increase or replace the butterfly spring.
　　2, due to unsuitable safety pins, safety pins caused by excessive load caused by cracking ring die, the solution in this case should be used to correspond to the company's supporting the provision of safety pins.
　　3, due to the effect of the iron removal device becomes worse so that the ring die work like surface of metal objects indentation, resulting in ring die cracking, so we must promptly check and clean up the iron removal equipment.
　　4, when the equipment is shut down for a period of time without using, not wash the mould, ring die die hole particles become hard, the next time out of the material is difficult to squeeze the pressure is too large and lead to cracking of the ring die, at this time we must immediately fill the non-corrosive oily material.
　　5, due to loading and unloading ring die with hard steel tools directly hammering ring die and lead to ring die cracking. If you have to install the ring mould with force, you should use a wooden hammer to minimize the damage to the equipment.
　　6,Feeding too much or replace the small aperture ring die to adjust the feeder in time, granulation as unbalanced production, resulting in increased load on the ring die, resulting in ring die cracking. At this time should be adjusted to feed the motor speed, adjust the change chin controller or electromagnetic controller.
　　7, the die cover hole wear becomes large and end face deformation, screw tie loose, resulting in ring die end face screw hole at the tear, this time you need to replace the die cover.
