WPC profile production

Developed by Amut:

Easywood is an extrusion system for WPC processing.

The Easywood system is suitable for:

• Direct extrusion end products;
• Compounding (without pre-mixing) and further extrusion.

Easywood extrusion lines or compounding lines are equipped with a gravimetric dosing system for each type of raw material, and are equipped with plasticizing, mixing and extrusion groups, using a counter-rotating twin screw extruder as the main machine.

Benefits of a counter-rotating twin screw extruder when using mixtures with a high content of vegetable fibers (up to 80%):

• high pressure extrusion capability;
• low screw speed and high torque;
• the temperature of the melt is far from the temperature of the beginning of the decomposition of the plant component;
• feeding zone suitable for low specific gravity;
• efficient degassing system to remove volatiles;
• Specially designed mixing zone for optimal separation of components and additives.

The extrusion systemEasywood requires only partial drying of the fiber, reducing:

• energy consumption;
• dimensions of drying equipment.
