  • What are the auxiliary devices of the twin screw extruder?

    The Conical twin screw barrel is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability, etc., it has been widely used in extruded produc...

  • What is the difference between Huahong analysis screw and lead screw?

    The screw is composed of a feeding section, a compression section and a metering section. The outer surface of the screw is a cylinder with a spiral groove or a cone with a conical spiral groove. Screws are used in plastic molding equipment, such as ...

  • Interpretation of twin screw extruder-barrel

    We know that conventionally speaking, the twin-screw barrel is connected by building blocks, and the connection method is flanged. The L/D (length-to-diameter ratio) of each barrel is 4:1, so the model is L/D=40:1. It is a 10-section barrel. Back to ...

  • What is the function of the screw and barrel of the injection molding machine?

    When the screw rod rotates and pushes the extruded material to move forward du, the external heating of the barrel conducts heat to the material dao, plus the gradual reduction of the volume of the screw thread groove, 1653 makes the material squeeze...

  • What are the characteristics of the barrel structure of the twin screw extruder?
