1. High output and low energy consumption.

2. Each gear in the hardened gearbox is heat-treated and finely ground, with an internal forced cooling system to ensure high efficiency, low noise and long service life.

3. Screw geometry parameters, reasonable design, for different raw materials, to do different products, the screw has different length-diameter ratio and structure, to meet the needs of different customers.

4. The heating section of the barrel is available in both grooved and smooth sections to meet the needs of different raw materials.

5. The screw and barrel are made of high performance alloy steel, which is resistant to wear and tear, corrosion and high strength.

6. The whole machine is compact and reasonable in design, convenient in operation and simple in maintenance.
