This guide provides a best-practices approach to troubleshooting capsule-filling problems when handling a sticky product formulation.
A sticky formulation is one of the most common causes of issues during capsule filling. A capsule filler requires tight tolerances between the machine’s tooling components, including the dosing disks, tamping pins, and sealing plate, as well as between the capsules and the segments’ bores, which hold the capsules during filling. Friction between the formulation and these tooling components during high-speed operation can cause a sticky formulation to cake and glaze onto the tooling surfaces, restricting the components’ movement and leading to inconsistent capsule weights, capsule splits, non-separation, and even machine crashes.
