Stevanato Group glass converting lines come as a turnkey package, including the forming unit and other process equipment, or as stand-alone modules. Completely automatic washing equipment to remove particles from the glass and reduce cosmetic defects is also available. Click on the modules below to learn more.

1. TUBE LOADERS Continuous-feeding glass tube loader: high reliability with limited human intervention
2. DIMENSIONAL AND COSMETIC CONTROLS  100% inline controls to ensure the highest quality standards
3. AFTERFORMING LINE  Gentle handling to the annealing oven, granting unaltered cosmetic quality and mechanical features
4. ANNEALING OVENS  Devised to guarantee an optimal thermal profile: highly performing and completely safe for the operators
5. AUTOMATIC PACKING MACHINES  The system picks the containers and automatically places them inside trays or blisters


Siliconization is a critical operation that influences container performance: distribution must be
optimized and monitored to ensure a safe and effective administration to the patient and to
guarantee drug quality.

Silicone, in the form of emulsions and/or oil, is primarily used as a lubricant. When applied to vials, its hydrophobic properties ensure a high restitution rate down to the last drop of product.

Moreover, the silicone layer minimizes the interactions between the product and the glass container, and prevents certain products from sticking to the internal surface, making the glass appear perfectly transparent.

Optimizing control of the process through precise automation, our siliconization lines are designed to:

  • Increase gliding performance between the glass and internal components (e.g. rubber parts)
  • Improve the flow of liquid solutions inside the container, reducing “dead volume” concerns
  • Reduce the interactions between the pharmaceutical product and glass container
  • Process the most common sprayed materials: silicon emulsion or silicon oil
