Hot Melt Extrusion in the Pharmaceutical and Food Industries

 · Single-screw extruders (SSEs) are predominantly used to melt and process polymers into continuous shapes. Twin-screw extruders. These are more advanced devices containing twin-screw systems with co-rotating or counter-rotating screws. Twin-screw extruders (TSEs) are used to melt polymers and mix them with other substances such as APIs and pigments.

The working principle of the injection molding machine is

The working principle of the injection molding machine is similar to that of the syringe for injection. It is to inject the plasticized molten state (ie, the viscous flow state) into the closed cavity by the thrust of the screw (or plunger). The process of obtaining the product after curing and setting.
