Stevanato Group has been developing glass-forming technology since 1971 when its subsidiary Spami was established. Spami was founded to design and produce high-speed, high-precision machinery for the production and control of tubular glass containers.

Thanks to its consolidated experience as a glass forming machine manufacturer, Spami designs its cartridge lines with an emphasis on all forming phases: glass tube feeding, the glass forming process, transport, annealing, and packing.

On-going technological improvements and the synergistic cooperation with Ompi – specialized in primary packaging for pharmaceutical glass – have enabled Spami to continuously improve its technological offer. In turn, this has led to accurate in-house equipment design, with constant monitoring of critical parameters capable of influencing forming precision.
Currently, Stevanato Group has the technology of reference for insulin pen cartridge production worldwide.

Stevanato Group cartridges forming lines are designed and built to ensure optimal mechanical durability, thanks to carefully selected raw materials for their construction and an extremely accurate assembly process.
Thanks to this optimized construction process, the lines have a reduced rate of obsolescence and their lifetime can exceed 25 years.

All the machines operate with the greatest mechanical precision and feature easy-to-use HMIs ensuring seamless high-speed production, fewer rejects, mechanical resistance in order to obtain compliant cartridges in terms of cosmetic and dimensional standards.

The range includes containers from 1 ml to 5 ml, including a special dual-chamber configuration – an innovative delivery method for liquid and lyophilized drugs that need to be mixed just before application.
