Conical twin-screw extruder is a counter-rotating extrusion machine; the shape of the screw is conical, from the feeding zone to forming zone, the screw and barrel are becoming smaller, and the pressure will become bigger, so we can add a high percentage of calcium carbonate into the extrusion products. Conical twin-screw extruder is designed to make PVC pipes, PVC profiles, WPC profiles, PVC pellets, SPC floor; it was invented in China and also produced in China. The speed of the conical twin-screw extruder is from 30-45rpm. It belongs to slow speed extruder.
Conical twin-screw extruder consists of a different structure compared to parallel twin-screw extruder (another type of twin-screw extruder). Compared with parallel twin-screw extruder and single-screw extruder , this efficiency makes the conical twin-screw extruder with higher reliability and superior extruder. Adding to its efficiency is the ability of the conical twin-screw extruder to reduce production costs. By simply adding more calcium carbonate when producing PCV profiles, PVC floors and pipes, the overall production cost can be reduced. This makes it easier for businesses and production industries to manufacture and produce plastic products by following a budget-friendly process using conical twin-screw extruders.
Advantages of conical twin screw extruder:
Although the conical twin screw extruder is a cost-effective machine in the market, it also has various advantages of use. These advantages make the conical twin-screw extruder a more reliable and suitable extruder choice for various plants. It also has an efficient exhaust. This exhaust ensures that every conical twin-screw extruder produces an excellent surface finish. This enhances the appearance and efficient performance of products made with this machine.
Finally, its nickel-based alloy bimetallic oval liner provides another distinct advantage of conical twin-screw extruders. This liner is used to increase the overall life of the conical twin screw extruder, making it a longer lasting machine for any manufacturing industry.
