Direct UV laser marking of tablets and capsules
 
Igor Murokh, Tri-Star Technologies, says:
 
This article describes the basic principles of UV laser marking and its applicability to solid oral dosage forms. It focuses on laser-surface interactions with emphasis on the role of titanium dioxide exposed to intensive UV laser pulses in the process of marking. Topics covered include experimental data and theory, advantages and limitations, and practical implementations.
 
In 2016, the global market for laser marking machines was estimated at $2.21 billion [1], yet only a handful of lasers are currently used for direct identification of pharmaceuticals. For decades, every major component required for direct laser marking of pharmaceuticals has been in place. Twenty years ago, approximately 22,000 laser marking machines were in use in various industries worldwide, some of which were using carbon dioxide (CO2) lasers to imprint lot numbers on the aluminum backing of pharmaceutical blister packs [2]. CO2 lasers were not suitable for marking individual tablets or capsules through the clear plastic of a blister pack, however, because CO2 radiation melts the plastic and destroys the package. Ultraviolet (UV) radiation, on the other hand, safely passes through a transparent blister and can be used to mark tablets or capsules pigmented with titanium dioxide (TiO2) [3].

Heat distribution and airflow channeling in the tablet coater
 
Q: How do heat distribution and airflow channeling affect a tablet coater's performance and coating quality?
 
 
Until recently, pharmaceutical manufacturers essentially had a choice between two airflow channeling systems for tablet coating: forced airflow channeled in the same direction as the spray mist to the tablet bed and forced airflow channeled through the tablet bed. In both systems, inlet air shoes supply the drying air to the drum and direct the airflow. The inlet air shoe is installed directly on the drum's exterior, and its position differentiates the two systems.

Multitip tooling—monoblocks, caps, and pin fixing
 
Q: What new multitip tooling options can we use to increase the productivity of our tableting process, and what changes would our existing press setup need to integrate them?
 
imageA: Steve Osborn, I Holland, says:
 
Multitip tooling (photo) provides the most efficient and cost-effective way to increase tableting productivity to meet a growing demand for increased output, offering many benefits over standard tooling.
 
Multitip tooling increases the number of tablets per cycle and reduces run time per output of tablets, which lowers maintenance per batch and reduces the press setup time for the quantity of tablets produced. It allows the number of tablets per turret rotation to be multiplied by the number of tips on the punches and can increase production in many cases by well over 200 percent.
