In some production enterprises in the extrusion die is very common, it is also known as extrusion dies, extrusion head or die. In the process, usually the polymer powder or granular form to the extruder barrel, under the action of the screw or plunger, the polymer along the spiral groove or cylinder is moved forward and gradually melt and become sticky fluid, and then by the barrel provided at the end portion of the die, the die is formed with a shape similar to the mold of a continuous body, and finally by cooling and sizing, can be molded into the desired shaped articles, such as various plastic pipe rod, sheet , steel doors, films, and other decorative baseboard. There are some manufacturers shut down after adding material to remove the entire place is about to die stand, without being fragmented demolition cleanup. Stop feeding although some cleaning effect, low density is not easy to paste, but the entire die easily remove heat at high temperature longer will inevitably break down corrosion runner. And down in the flow path of the material is cooled back to cause some thin shrink small gauge bars, deformed strut, and precipitates fouling and other streaming tract alone is clearly not afford the downtime, so after the shutdown should promptly die slice disassembly cleaning, Demolition should pay attention to the use of brass rods inserted into the wedge groove even forced to remove from the mold, not use wedge iron rods, unilateral force to pry or hammer, so as not to damage the die face split and locating pins, salvage runner beak clamp to live within the available means of compressed air and blow out deadlift.
