The rise of the lower punch in a rotary tablet press is usually caused by excessive filling material, which overloads the die cavity and prevents the lower punch from returning smoothly under the machine's rated power – often leading to jamming or even a machine stall. The simplest remedy is to reduce the fill depth or adjust the powder scraper position accordingly.
This equipment is widely used to compress granular materials into round or shaped tablets in high‑volume production. The fit precision between the lower punch, upper punch, and die directly affects operational stability. If punch movement abnormalities persist, besides adjusting the fill, worn tooling or improper clearance may also be the root cause.
We can provide precision custom‑made and replacement services for lower punches and other key tooling components for rotary tablet presses, based on your machine model and punch drawings, ensuring dimensional accuracy and smooth motion to help reduce unplanned downtime. Hansheng Automation supports made‑to‑order manufacturing per customer prints, with flexible response for single‑piece or small‑batch requirements, making your equipment more reliable.
