Preventing Tablet Capping

Q: How do we determine the cause of tablet capping during production and prevent it from occurring? A: Robert Sedlock, Natoli Engineering, says:  The term capping in tablet manufacturing refers to a tablet failure, a break across the horizontal plane, that you find when performing a breaking force or friability test. Many factors can contribute to… Read More

Tablet Press & Tooling Maintenance

Q: What’s the proper way to maintain my tablet presses and tooling? A: Stephen Natoli says: Many factors can reduce the life expectancy of tooling and tablet presses, such as abrasive or corrosive formulations, press or turret wear, improper tooling setup on the press, and mishandling of tooling by technicians. Creating and following a tooling… Read More

Reducing Costly Scale-up Problems

Rushing A Product to Market Can Yield Some Expensive and Painful Lessons When scaling a new drug formulation from development into manufacturing, there is often a reality check regarding process scale-up and formulation performance at production levels. Problems with capping/lamination and sticking/picking are often first realized when a formulation is introduced to a level of… Read More

An Essential Part of the Tableting Process: Clean Tooling

The number one reason for tablet press failure is lack of tooling cleanliness. Dirty tooling may cause binding, which can damage tooling and tablet presses. Keeping tools clean can decrease premature tool wear and allow lubrication to be more effective as well as reduce the possibility of product cross-contamination. Additionally, clean tooling is critical to… Read More

Maximizing Your Tooling ROI

Tablet compression tooling is a considerable investment for your company. Quality tooling and a proper maintenance routine are critical for efficiently producing high-quality tablets. Polishing is one of the most inexpensive ways to maintain tablet quality, reduce production-related costs, and decrease tablet-press downtime. Punches and dies experience wear during tablet production, this can lead to tooling… Read More

Which Tablet Compression Training Is Right for You?

In the October 22, 2018, issue of Solid Dose Digest, a reader asked, “I need tablet compression training. How do I decide which course is right for me?” Natoli Scientific Director Jonathan Gaik answered: Tablet compression is complicated, and most who work in the industry learn on the job, but a growing number of options… Read More

Which Coating Can Help Solve Your Tableting Issues?

Sticking and picking are ubiquitous problems in tablet manufacturing and generally arise from either formulation or tablet design inadequacies. Sticking occurs when formulation granules stick to the face of the punch cup. Formulation sticking in the letters and characters of punch embossing is typically referred to as picking. Both result in tablet defects and lower… Read More
