A method of manufacturing a foamed molded midsole by inserting a hollow box containing a foamable material in a mold

摘要

assignment;The method of manufacturing the foamed product by preliminarily forming the foaming foam by plate, cutting it according to the dimension, putting it into the mold again, applying heat and pressure, and cooling the foam to manufacture the midsole has been excessively consumed with lots of material loss (LOSS) Molding method of inion extrusion method Expansion of mold In the process of exposing expanded midsole to the atmosphere, the defective dimension ratio is high due to the shrinkage phenomenon. The equipment cost that prevents compressed air from flowing out to the outside is excessively spent, There are disadvantages that it should be used after modification.; Solution;By vertically stacking several sheets of foamable material inside a commonly used midsole mold, high pressure can be applied only by the normal press pressure, so that even if the material receives heat and pressure, the foaming force is suppressed and momentarily released And then expanded and expanded in the mold so as to be compressed and foamed while being cooled.
