Temperature Parameters (In °C):
Your global partners in solid dosage systems
Optimizing Material Heating:
• Contact Heating is recommended
• Platen surface: Minimize friction
• Sealing temperature & pressure
• Cool as well as possible
Your global partners in solid dosage systems
• IN COLD FORMING:- Mechanical forming by PLUGS- Plug material – TEFLON
• Can cause formation of Pin-Holes or Material Tear
• Installing PIN HOLE DETECTORS for forming and lidding foils
