CB Automation approach to high-quality pen injector production

Case Study

Injectable drug delivery systems are driving rapid growth in pharmaceutical manufacturing. As drug delivery OEMs and CMOs compete to bring pen injector to market, they face intricate engineering and stringent quality demands. CB Automation delivery automation-partners with device manufacturers to deliver turnkey pen injector assembly and in process testing lines. Its solutions combine compact footprints with end-to-end quality assurance, ensuring you stay ahead in a dynamic market.

Challenge: maximizing flexibility in pen injector production

A leading global drug delivery specialist needed to assemble two distinct pen injector models, each with different part counts and checks, on a single production line. The requirements were clear:

  • One line, two models: rapid changeovers between pen injector components without expanded floor space
  • Cost optimized design: balance capital expenditure against automation performance
  • Uncompromised quality: 100% inline inspection and process validation to satisfy regulatory and patient safety standards

Solution: semi-automated pen injector assembly platform

CB Automation engineered a pen injector assembly line that harnesses human skill alongside automatic precision:

  1. Linear Chassis Layout
    A free pallet conveyor runs the full length of the line, minimizing footprint while maintaining efficient part flow for pen injector assembly.
  2. Ergonomic Manual Loading Stations
    Operators load components into workpiece at stations equipped with safety barriers and process validation sensors, eliminating loading errors during pen injector assembly.
  3. Automated Stations
    Automated groups perform force fitting, torque coupling, and high-resolution vision inspections. In process force, torque, and vision controls verify every pen injector assembly step, delivering consistent quality at scale.

This blend of manual dexterity and automation precision enables swift tooling swaps; no extra tooling areas required and reduces capital costs compared to fully automatic systems for pen injector assembly.

Key benefits of CB Automation pen injector assembly solution

  • Space Efficiency: compact linear design consolidates all pen injector assembly and testing functions, freeing valuable cleanroom area.
  • Cost Savings: semiautomated approach lowers CAPEX, while inline quality checks cut OPEX by reducing rework.
  • Guaranteed Quality: continuous force, torque, and vision inspections ensure every pen injector sub-assembly meets exacting specifications for pen injectors.
  • Scalable Throughput: min. output capacity to enable small batches production to get authority approval and test market interest.
  • Full Traceability: comprehensive data logging tracks each pen injector component from origin to final assembly for audit-ready compliance.
