Component Specifications

Definition
The Insertion Plunger is a critical component within stoppering stations of automated filling lines, designed to precisely insert rubber or synthetic stoppers into vials, bottles, or containers. It operates through controlled vertical motion, applying consistent force to seat stoppers securely while maintaining sterility and preventing product contamination in aseptic environments.
Working Principle
The plunger operates on pneumatic or servo-driven linear actuation principles. During the stoppering cycle, it descends with controlled force to compress and insert the stopper into the container neck, then retracts cleanly. Position sensors and force feedback mechanisms ensure proper insertion depth and prevent damage to containers or stoppers.
Materials
Typically manufactured from 316L stainless steel for pharmaceutical applications or food-grade materials like PTFE-coated aluminum for beverage industries. Surface finishes range from Ra 0.4μm for pharmaceutical to 0.8μm for general use, with optional hard coatings like DLC for wear resistance.
Technical Parameters
  • Speed 60-120 cycles/min
  • Diameter 8-25mm
  • Stroke Length 50-150mm
  • Surface Finish Ra 0.4-0.8μm
  • Operating Force 50-200N
  • Temperature Range -10°C to 80°C
Standards
ISO 2852, ISO 15378, DIN 11864
