Conveying Screw Elements

The main role of the conveying element is to efficiently and stably push the material in the barrel with positive displacement. The size of the lead determines the conveying speed. The larger the lead, the faster the conveying speed. Conversely, the smaller the pitch, the slower the conveying speed (pitch range 0.5D-2D). The conveying elements can be divided into self-wiping elements and non-self-wiping elements. Suitable elements can be selected according to different process conditions.

Kneading Screw Elements

The main function of the kneading elements are plasticizing and mixing (dispersion and distribution). The effect of dispersion and distribution is realized according to the thickness of each kneading disc and offset angle.

Mixing Screw Elements

The mixing screw elements is mainly includes TME, SME and ZME, which are mainly used in distribution.

Screw Barrel

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

Screw Shaft

The screw 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.

Alloy liner

The alloy liner is usually a cylindrical structure that is tightly installed inside the barrel of the screw extruder. It is generally made of alloy materials with high hardness and wear resistance, and common alloys include nickel based alloys, cobalt based alloys, etc. These alloys are formed through special casting or processing techniques, and their inner walls have a very smooth surface, ensuring smooth passage of materials during extrusion.
