1. Power saving. Can save 30% power WITH a similar product in the market. It means saving 30% on electric charges for factory owners.

2. More productive. Because our screw diameter is smaller.

3. Machine with converters, protect the whole machine. When there is a low electrical current start-up machine, it protects the gearbox and protects the screw.

4. Using more wearable material for the barrel and screw. Longer life for barrels and screws
