PharmaSpray helps reduce the amount of dry lubricant in the compression blend while applying an optimized amount of lubricant to the upper punch face, die wall and lower punch face.
Standard features include upper and lower punch compaction force measurement, ejection force measurement, and upper punch displacement.
Natoli's turrets feature the following: steel die tables; eyed upper punch guides; lower punch retainers (except B2 and DS3) and 3-piece die lock screw with stainless threaded ends.
Upper punch sockets are keyed for versatility to accommodate all shapes and sizes.
Upper punch sockets are keyed for versatility to accommodate all shapes and sizes, The design isolates the upper compression area from the lower cabinet and the machine is protected in a rigid stainless steel enclosure.
The principal functions of the Galenic operating package include: 5-channel display curves of the main compression force, pre-compression force, ejection force, upper punch stiffness, and lower punch stiffness; force-displacement diagram of main compression force and pre-compression force; calculation of mechanical work; punch station selection; display at full rotation; zoom function for x and y displays; measurement storage on hard disc; data export and import via media storage or network; data evaluation on separate PC; printing and directory functions; consistent use of existing technical equipment and integration facilities; the latest standard engineering, hardware and software components.
At every precompression, the upper punch hits the upper roller and is initially pushed downwards into the die.
The upper punch will push the upper precompression roller assembly up and continue its way under the roller.
Features include harmonic cam profile; pre-compression; three wheel mechanical feeder; easily adjustable compression zone, loadcell and pressure indicator; precise, smooth punch rail; compression force buffer system; direct turret drive; upper punch track cover; fast changeovers; keywayed upper punch sockets; touch screen controls; fully enclosed and quiet operation - plus an array of options.
Turrets feature the following: steel die tables, keyed upper punch guides, lower punch retainers (except B2 and DS3), 3-piece die lock screw with stainless threaded ends.
main pressure, pre-pressure, ejection force and upper punch tightness, can be processed, stored and analyzed.
We also like the matching feature which automatically matches an upper punch with a lower punch by its working length.
