VERTICAL EXTRUDER
FOR PHARMA AND HIGH TECH
The RONDOL patented “All-in-One” vertical twin screw extruder further enhances the proven performance of the Hot melt Extrusion (HME) technology for producing the next generation drugs, devices and materials, such as :
- Drug Formulation & Manufacturing
- Materials Science Research
- Compounding Solutions
- Personal Care & Cosmetics
- High temperature polymer parts
- Molecular Dispersion
- Bio Availability
- Production related development (fibers & filaments, films & sheets, rods & strand, tubes)
- 3D printed medical devices
From horizontal classic to vertical “All-in-One” :
- Longer barrel for smoother mixing of fragile active principles (API).
- Precise monitoring of process temperature for APIs with narrow range from melting to degradation.
- New design for external parts to avoid contamination between lots.
- New design for internal parts to make change over “easy” in between lots.
- Vertical format to decrease capital intensity (machine footprint divided by 5).
- Optimized configuration for 3D with strong and stable pressure at the die.
- Full range of plug and play downstream accessories
- Last mods post COVID-19 trials: new easy feed hopper, autonomous cooling for each zone.
