The working principle of a stoppering machine is a vital aspect of pharmaceutical manufacturing, ensuring the quality and sterility of the final product. Stoppering machines, designed specifically for pharmaceutical applications, follow a systematic process to seal containers such as vials or bottles with precision and consistency.

The first step involves feeding empty containers into the machine’s conveyor or feed system. These containers can vary in size and material, depending on the specific pharmaceutical product being manufactured. Simultaneously, the machine loads stoppers or closures into a separate hopper or feeding mechanism. These stoppers are typically made of materials like rubber or plastic and come in various sizes and shapes to match the containers. To ensure accurate stoppering, the machine aligns the containers and stoppers perfectly. This alignment is crucial to avoid misalignment, which could lead to leakage or product contamination.
