Pen injector preassembly demands 160-PPM precision: LVDT/vision systems, tolerance control, and GAMP 5 challenge testing ensure ISO 11608 compliance.

Force-displacement monitoring and LVDT verification may solve the cartridge press-fit challenge for greater than 99.5% yield.

GLP-1 / insulin demand is straining CDMO fill-finish capacity. This piece examines bottlenecks in automated pen injector assembly and strategies to optimize operations.
