.... The high pressures used in such processes as injection molding can both reduce some of the effects of shrinkage, by packing out the mold, and cause distortion of the product, by increasing internal stresses. With glass-fiber-reinforced materials, shrinkage of the resin away from the surface during molding...

...) fiber/filament, and (d) profile Typical Materials and Their Properties Materials to be used in extrusion are typically thermoplastics with high viscosities (low melt index) and high melt strengths. The typical melt flow index (MFI) for extruded thermoplastics ranges from <1 to ~10 g/10 min...
