Conical twin screw barrels
are a type of screw barrel used in plastic extrusion machinery. They consist of two conical screws that rotate within a barrel and are used to melt and mix plastic resins as they are pushed through the barrel and out through a die. The conical shape of the screws helps to prevent material from getting stuck or accumulating in the barrel, allowing for a more efficient and consistent extrusion process. Conical twin screw barrels
can be used in a variety of applications, including the production of film, pipes, profiles, and sheets. They are also used in the manufacture of various products, such as food packaging, automotive parts, and medical devices.
Conical twin screw barrels have several advantages over other types of screw barrels, including:
1.Improved mixing and plasticizing: The conical design provides more efficient mixing and plasticizing of the material, resulting in improved processing and end-product quality.
2.Enhanced self-wiping: The conical shape allows for better self-wiping of the barrel, reducing material buildup and promoting longer barrel life.
3.Greater output capacity: Conical twin screw barrels typically have a larger output capacity than other screw designs, allowing for increased production rates.
4.Better material utilization: The conical design ensures that the material is utilized more effectively, reducing waste and increasing efficiency.
5.Enhanced process control: The conical twin screw design provides improved process control, allowing for finer control over processing parameters, resulting in improved product quality.
