Innovative Design

Negative Wall Angle Structure

Improvement of anti-bridging function because material compression decreased by negative wall angle design. It handles wide material applications.

Structure for High Screw Fill of Material

Improved of screw fill of material because agitator push material into screw part. Compare to our conventional equipment, it achieves accurate and constant mater ial flow.
