The Research And Application Of The Palletizing Die Plate

The Palletizing Die Plate is a key part of all extruder. Since it is used in high temperature, high pressure and great friction conditions, problems such as spallation, uneven wear, etc. would easily occur thus causing the off-spec. products, which means that the die plate need to be replaced with a new one. This is a big financial burden for pur factory because it is very costly to import the die plates every time. To save money, or to say to cut down the production cost, this paper suggests to have the die plate made in China.To solve the problems with the existing die plate while aiming to fabricate in China the die plates that will have the same performance as the imported ones, a cooperative study has been done between our factory and Liaoning Chemical Machinery Factorv by analyzing and measuring the body, the holes, heater, strand Of the die plate, etc.This. paper has analyzed the main structural features of the die plate used for PE extruder, described its working mechanism and thus suggested to have it made in China based on good mastery of its structure.
