Extruder Part Twin Screw Compounding Extruder Screw Element in Screw Barrel

Threaded elements
It is divided into forward conveying threaded elements and reverse type. The main difference is that the direction of action of the forward threaded element is the same as the extrusion direction, while the reverse threaded element is opposite. The reverse action can hinder the forward conveying of materials and its main function is to prolong the residence time of materials in the barrel, thereby improving the filling degree and material pressure.

Conveying elements:
It is divided into forward conveying threaded elements and reverse type.

Cutting elements:

Mainly refers to pinch blocks, which provide high cutting force and have the ability to distribute and disperse
the mixture. They are always used in pairs or in series. The pinch blocks have a certain angle and commonly used parameters are 30°, 45°, 60°, and 90°. Different parameters have different functions and effects.

1.Better temperature stability,
2.Excellent corrosion resistance,
3.Abrasion resistance
4. Well performance in low energy consumption and injection molding
5. good heat resistance.
6. High hardness, HRC up to 65.
7. self-cleaning performance

3. All components are finished by CNC grinding after heating, the shape error is controlled within ±0.015, the distance between the kneading block and the thickness tolerance is controlled within ±0.03, the length tolerance is controlled within ±0.01, and the surface roughness of the shape All ≤ ra0.8, completely eliminating the influence of heat treatment deformation on component quality.
