Automatic high-precision metering and feeding for multiple materials, ensuring accurate formulation control.
Automatic material weighing to ensure consistent and stable product quality.
The barrel is equipped with integral tungsten carbide alloy liners, extending service life and reducing maintenance costs.
Screw elements made of powder metallurgy (PM), featuring high wear resistance and mechanical strength to ensure long-term stable operation.
The side feeding design allows glass fibers to be introduced into the main material flow in a controlled and sectional manner, preventing fiber agglomeration and improving dispersion uniformity in the matrix.
Low-shear feeding helps preserve fiber length (especially long fibers of 6–25 mm), reduces fiber damage, and enhances final product density through efficient high-vacuum degassing.
The buffer hopper is equipped with an agitator to prevent material bridging and improve feeding efficiency.
Equipped with small bag and big bag feeding stations, quick-opening strand die head, cooling water tank, air knife, gantry pelletizer, lifting conveyor, finished product homogenization silo, and automatic bagging system to improve overall production efficiency.
