With regard to production specifications, LESUN not only offers standard twin screw extruder parts made by general extruder screw manufacturer, but also provides special-purpose extruder parts design and manufacturing service according to your requirements.

Conveying Screw Element

The main function of the feed screw design is to help the material forward in the cylinder, and it will determine the conveying speed according to the size of the lead. The larger the lead, the faster the conveying speed. Conversely, the smaller the lead, the slower the conveying speed. Conveying extrusion screw design can be divided into kneading elements and non-kneading elements. kneading and non-kneading can be selected according to the shape of the material.

Kneading Screw Elements

The main function of the compound screw element is mixing, which is used for the distribution and dispersion of the materials. The strength and weakness of the dispersion and distribution effect are determined according to the thickness of each disk. Meantime, the larger the angle, the stronger the shear. Conversely, the smaller the angle, the weak the shear.

Mixing Screw Element

The german twin screws element included TME, SME, ZME, CME, SFT, eccentric elements, multi-head elements, extruder feed screw and most teeth elements serve to enhance dispersion.

Screw Barrel

The extruder screw manufacturer and feed screw manufacturers, Lexun, provides different screw barrel types, including open barrel, closed barrel, open side barrel and liquid barrel for your needs.

Screw Shaft

The shaft spline type is divided into single-key , rectangular spline and involute spline.

Materials can be selected from China, Germany and Japan made.

The standards for splines has Chinese standard, German DIN5480 (or DIN5482) and Japanese standard.

Currently the maximum length of the shaft we can supplied up to 9 meters.
