Summary

  • Customer Need / Challenge

    As autoinjectors become essential tools for delivering weekly medications, especially in fast-growing therapeutic areas like weight-management drugs. Manufacturers must ensure that each device performs safely, consistently, and comfortably for the patient.

  • Interface Solution

    Interface’s ideal solution is by integrating the SMTM Micro S-Type Load Cell into an automated autoinjector test machine, equipped with a precision linear actuator. The SMTM offers the accuracy, sensitivity, and small size factor required for capturing the force profile of an autoinjector. The measurements can be captured using the 9330 Battery Powered High Speed Data Logging Indicator through an SD card, or laptop directly.

  • Results

    The SMTM Micro S-Type Load Cell provided more stable measurements and better insight into force and movement behavior, engineers can confidently verify compliance with medical standards and deliver safer, more consistent autoinjectors to market.

Materials


  • SMTM Micro S-Type Load Cell

  • 9330 Battery Powered High Speed Data Logging Indicator with optional SD card

  • Autoinjector test machine

  • Customer Laptop

How it Works


  1. The autoinjector is mounted securely in a test fixture. A linear actuator presses the internal plunger at a controlled, consistent speed.

  2. The SMTM Micro S-Type Load Cell is placed in line with the actuator to measure all forces during the injection cycle. When connected to the 9330 Battery Powered High Speed Data Logging Indicator, force results can be captured using an SD card, then displayed on another PC or laptop.

  3. Engineers review the synchronized data to confirm the autoinjector delivers smooth operation, accurate dosing, and reliable performance.
