Insulin Pen Assembly and Testing, Step by Step
How an insulin pen or pen injector is assembled by machine in three steps — barrel assembly, assembly and testing, and camera inspection with tray loading — with the standard machines we have supplied to Bangladesh.
What is insulin pen assembly? Insulin pen assembly is the process of putting an insulin pen together from its parts, testing it, and loading the good pens into trays. Our machines cover three steps: assembling the pen barrel, assembling and testing the pen on one machine, and final camera inspection with tray loading. We have supplied these machines to Bangladesh.
Key takeaways
- The pen line has three machines: the barrel assembly machine, the assembly and testing machine, and the inspection and tray loading line.
- All three standard models run on a chain conveyor, two pens per cycle: 50–60 pieces per minute for the barrel, 50 pieces per minute for assembly and testing, and 60 pieces per minute for inspection and tray loading.
- The assembly and testing machine checks torque in both directions, length, the dose window and its zero mark, and sorts out faulty pens.
- Cameras and sensors check the spring, the window, cracks, raised gate marks and the zero mark; a four-axis robot loads the good pens into trays.
- Every machine is set up for your own pen parts; send drawings or photos and your target output.

The three steps of pen assembly
1. Assemble the pen barrel. Pen barrels come from a hopper, are screwed and pressed together, and then the spring and the cap go on. The insulin pen barrel assembly machine runs on a chain conveyor, two pens per cycle, at 50–60 pieces per minute, with a check after each step and faulty pieces sorted out. The standard model measures 3100 × 1400 × 1800 mm.
2. Assemble the pen and test it. The machine assembles the pen, then tests torque in both directions, length, the dose window and its zero mark. A gripper head presses parts into the pens on the chain, vibratory bowls feed the parts, and faulty pens are sorted out. The standard model runs 50 pens per minute, two per cycle, and measures 5400 × 1600 × 1800 mm.
3. Inspect and load into trays. Cameras and sensors check each pen, and a four-axis robot loads the good pens into trays. The line checks the spring, the window, cracks and raised gate marks, and the zero mark in the window; faulty pens are sorted out. The standard model runs 60 pens per minute, two per cycle, with empty trays fed in and full trays taken out.
