True or False: In plastic molding processes, the screw can be divided into a feeding section, a homogenization section, and a compression section; the homogenization section is the last part of the screw and is also known as the metering section or extrusion section. ?√?
In plastic molding processes, the screw can be divided into a feeding section, a homogenization section, and a compression section. The homogenization section is the last part of the screw; it is also known as the metering section or extrusion section. Wrong
Error. The screw is divided into a feeding section, a compression section, and a homogenization section; the homogenization section is also known as the metering section, but it is not involved in extrusion.
In plastic molding processes, the screw can be divided into a feeding section, a homogenization section, and a compression section. The homogenization section is the last part of the screw; it is also known as the metering section or extrusion section. (Incorrect) The function of the homogenization section is to further homogenize the plasticization of the melt, and to ensure that the material flow exits evenly from the nozzle channel at a constant volume and pressure.
