Shear Controlled Orientation in Injection Molding of PLLA

5 Shear Controlled Orientation in Injection Molding of PLLA 

A technique based on injection molding, as it is a versatile, efficient and highly reproducible process, and capable of fast production of complex geometric shapes with tight dimensional tolerances has been studied. The mechanical property of PLLA can be optimized up to a certain level through manipulation of thermomechanical environment of conventional injection molding. Non-conventional injection molding processes like shear controlled orientation in
