The quick way to produce safe insulin pens

Insulin Pen

Diabetes is on the rise globally: around 10 million people become ill with it each year. There is an associated high demand for insulin pens for self-medication. These pens need to be safe and user-friendly so that they pose no risk to patients when used. An automated assembly system guarantees high quality.

Many people with diabetes use an insulin pen for their insulin therapy. The device is the size of a normal pen and makes it easy to accurately dispense the required units of insulin. The insulin pens must be of a high quality. They must not break when used by the patient, which would put the patient at risk.

High-quality insulin pens thanks to automated system

The requirements can be fulfilled with an automated system. The system produces up to 300 pens per minute, keeping the stresses and pressure constant, as the glass in the syringes must never be broken by irregular pressure. The servo press kit from Festo makes this possible. The kit performs three joining and pressing steps: inserting the cartridge, needle and spring, plus the glass and plastic covers. As part of this, it joins together the individual components of the syringe, always maintaining the exact amount of pressure and stresses required, thus guaranteeing the quality of each individual syringe.

Rapid format changes

Depending on the size of the insulin pen being produced, a different pressure may be needed to press together the component parts. The servo presses can be flexibly adjusted to different dimensions. They consist of pre-programmed software, a control system and standard electric drives and can therefore be quickly and easily integrated into the system and adjusted. This enables rapid format changes. The precisely adjustable pressing and joining forces ensure consistently excellent quality and low rejection rates – including for the different sizes.

The degree of automation for the system can also be adjusted. The system can be expanded with automatic feeds and stations to increase performance. This enables custom solutions to be provided for many different applications.

The degree of automation for the automatic assembly machines can be scaled as needed and can also be adjusted retrospectively.
