When compounding within high throughput ranges, the seamless interaction of all process stages, while minimizing sources of error, is a decisive key to success. One important contribution to such high throughput rates is our ASC Automatic Strand Conveying System that automatically transports the extruded strands from their discharge from the die head to the pelletizer. In its largest size, the ASC 700, it successfully accomplishes the task in systems used for manufacturing polyamide compounds at throughputs of up to 6000 kg/h.
The SK92 die head that we optimized especially for processing in this high throughput range generates 100 strands in a single row, and 160 strands in a double row. Its intelligent heating/cooling concept creates a very homogeneous temperature distribution across the entire width of the die head. Furthermore, the optimized flow geometry enables uniform melt discharge with only minimal pressure loss.
