These methods include: injection molding, blow molding, thermoforming, transfer molding, reaction injection molding, compression molding, and extrusion. Extrusion is a metal working process that produces continuous lengths of uniform, non-uniform cross-sectional area from a metal billet, solid or hollow, by causing the billet to flow under high pressure through a restricted opening called die which is so shaped as to impart the required form to the product. to produce solid dispersions of the active pharmaceutical ingredient (API) in the polymer matrix. The plastic granules pass through a pipe with a rotating screw, which forces the granules forward into a heated barrel, where the melting occurs. Characteristic of the process is that plastic deformation takes place under high hydrostatic. Extrusion Process The extrusion process converts a solid plastic feedstock material into a molten viscous fluid, and then to a finished solid or flexible film product for practical use. EXTRUSION ; Continuous Process ; In principle, the plastic raw material is plasticated by means of a screw plastication unit and the molten material is continuously pumped out through a standard orifice (die) in order to take the shape and then the shape is set by cooling/sizing system. Wire or rod drawing: similar to extrusion, except that the workpiece is pulled through the die opening to take the cross-section.
