Canadian extruder manufacturer Deltaplast has branched our from its traditional single-screw designs with the introduction of a parallel twin-screw model. The 75-mm, counter-rotating extruder is directed at the PVC pipe and profile market.
Marcus Koch of Deltaplast Machinery Ltd. (Concord, ON) explains that the company originally served the pipe and profile market with single-screw extruders, but has found more demand recently for the twin-screw design.
"Many PVC extruders have switched to using powder and dry blends, and twin-screw machines are considered better for those types of materials when you’re aiming for high throughput," he says.
According to Koch, most of the larger, global extruder manufacturers offer a conical twin-screw design in the 75-mm size for this market in North America. In Europe, parallel designs are more readily available.
