    摘要: An extruding system includes a melting unit configured to convey a polymeric material, a mixing unit configured to mix the polymeric material with a blowing agent to form a mixture, an injection unit configured to inject the mixture, a first flow control element disposed between the melting unit and the mixing unit, and a second flow control element disposed between the mixing unit and the injection unit. A method of extruding includes conveying a polymeric material from a melting unit to a mixing unit, conveying a blowing agent into the mixing unit, mixing the polymeric material with the blowing agent to form a mixture, conveying the mixture from the mixing unit to an injection unit, and discharging the mixture from the injection unit, wherein flow of the polymeric material is controlled by a first flow control element, and flow of the mixture is controlled by a second flow control element.
