Ultra high mixing MD-UB screw
Click an image to enlarge it.
Extremely high-level uniform melting is obtained for PP, PE, and PS by using optimal shearing and partitioning actions of a multi dam that has a polygon cross-sectional shape. As a result, stable molding of large, thin walled molded parts is possible.
