Shear-controlled orientation in injection

Shear Controlled Orientation in Injection Moulding (SCORIM)... 

Shear controlled orientation in injection moulding (SCORIM) is based on the progressive application of macroscopic shears at the melt-solid interface during solidification in the moulding of a polymer matrix. 

Application of shear-controlled orientation in injection molding of isotactic polypropylene... 

The conventional injection molding of polypropylene is introduced in the related chapter. This chapter extends the subject of injection molding of polypropylene with the addition of shear-controlled orientation in injection molding (SCORIM), which has proved to be an excellent way of managing the morphology and hence the physical properties of polypropylene [1, 2].
