High product quality, large capacity and low energy consumption. Our company has independently developed high-speed and high-capacity die heads by introducing and absorbing foreign advanced technology. The relationship between the melt flow rate, flow rate and the pressure in the die cavity, as well as the disturbance of the whole melt flow caused by the differential flow produced by the coextrusion of raw materials with different viscosities, were calculated mathematically.
The changes in physical means and manufacturing can minimize the pressure when the melt extrudes the die, reduce the functionality of various raw materials with different viscosities in the melt, and the melt can be extruded uniformly with undifferentiated flow to avoid melt damage. The die head has a reasonable and compact structure, accurate, short and smooth flow channel distribution, no dead corner accumulation, reduces the disturbance in the melt movement, is suitable for extrusion molding of various materials, and overcomes the flow anomalies caused by the common extrusion of a variety of materials with different viscosities. With few crystal points, the output is large, and energy consumption is low. Compared with the conventional die head, the extrusion amount is increased by about 40%.
