Pressure fluctuation is caused by plastic extrusion granulation quality is one of the most important factors of instability, pressure fluctuations and the use of extrusion temperature, cooling, continuous operation is closely related to such factors as the length of time.

When an exception occurs, immediate removal of the exclusion, you must reorganize production should decisively stop, will prevent the increase in waste, can prevent the occurrence of accidents.
