Application of hot melt extrusion technology in pharmaceutical solid dispersions

I. Technical Principles and Advantages for hot melt extrusion Hot melt extrusion (HME) technology utilizes thermodynamic and kinetic principles to transport, shear, melt, and mix active pharmaceutical ingredients (APIs), polymer carriers, and functional excipients within a heated barrel using intermeshing screws. This forms a uniform and continuous melt, which is then extruded through a die

Desktop Extruder For Blown Film, Wire and Granulation

When desktop extruders are mentioned, many people immediately think of “3D printing filament machines.” However, by changing the die head and auxiliary equipment, the same desktop extruder can produce cast films, blown films, sheets, granulation, and even melt spinning. This is the concept of a “desktop polymer processing platform” advocated by Hartek. I. Universal Main
