发明名称 EXTRUSION HEAD, PRIMARILY, FOR EXTRUSION OF CELLULAR POLYCARBONATE SHEETS
摘要 FIELD: process engineering.SUBSTANCE: extrusion head, a mandrel, integrated with mandrel holder, is made of stainless steel and represents the internal part of split spinneret integrated with cellular plastic production line. Invention ensures the mandrel forming part shape by making the chamfers over the entire length of the mandrel forming part at the points of two top angles of mandrel forming part for construction of hexagonal figure. Said chamber represents an equilateral right triangle in cross-section.EFFECT: higher total load bearing capacity and light translucence.2 cl, 15 dwg
