  •   High speed and high capacity die
      The development requirements of the film blowing machine: high product quality, large capacity and low energy consumption. Our company has absorbed foreign advanced technology and independently developed high-speed and high-capacity die. The die mathematically calculates the relationship between the melt flow rate, the flow rate and the internal cavity pressure of the die, and the disturbance of the overall melt flow caused by the differential flow produced by co-extrusion of a plurality of different viscosity raw materials. By physical means, manufacturing changes, the pressure of the melt extrusion die is minimized, so that the functionality of a plurality of different viscosity raw materials in the melt is reduced, and the melt is uniformly extruded without difference flow to avoid melt fracture. The die structure is reasonable and compact, the flow channel distribution is precise and short, smooth, no dead angle accumulation, reducing the disturbance in the melt movement, adapting to the extrusion molding of various materials, and overcoming the multiple extrusion of different materials. The resulting abnormal flow, less crystal point, large output, low energy consumption, about 40% increase compared with the conventional head extrusion.
