TECHNICAL FIELD

[0001] The utility model relates to extrusion die technical field, concretely is a die extrusion end material removal structure. BACKGROUND

[0002] Die buildup, also known as die drool or die deposit, is related to the stress at the die exit. The resin moving along the inner surface of the die is relatively slow, and then suddenly accelerated when flowing out of the die. This sudden acceleration causes stress in the melt, and under the action of stress, the low molecular weight polymer part and other components in the melt will separate from the polymer melt and deposit on the die exit; it causes many problems, from surface defects visible on the extrudate to process disorder, and even product scrap.
