Q2：Under what circumstances does the tablet pressing machine need to increase the cost?
A：Normally we divide tablet press machine into different series, ZP-Series, ZPT-Series, GZP-Series and non-standard FZP-Series.
ZP-Series is our standard tablet press machine which can do Max. 25mm diameter.
ZPT-Series is our improved type tablet press machine which comes with automatic lubrication system and all features the same to high speed tablet press machine, just with slower rotation speed than high speed tablet press machine.
GZP-Series is our high speed tablet press machine which can do Max. 110rpm/min with Max. 25mm diameter.
FZP-Series is our non-standard tablet press machine which can be customized according to client requirement, especially when you have bigger tablet size which exceed our 25mm diameter.
Q3：The difference between the European standard B punch and the European standard D punch in the tablet pressing machine.
A：European standard: IPT
D-type punch refers to the diameter of the punch rod: 25.35mm, the middle mold: 38.1mm,
B-type punch refers to the punch diameter: 19mm, the middle mold: 30.16mm,
BB type punch refers to the punch diameter: 19mm, the middle mold: 24mm,
Therefore, after confirming the die type, the tablet diameter is determined.
In other words, after confirming the maximum sheet diameter, the type of die can be confirmed.
Q4：How many sets of molds can be changed at most for a tablet press machine?
A：Change as much as you want within the size range.
Q5：What is the Customization mold requirements?
