Enhancing performance: precision siliconization

Once the vial is formed, the internal surface treatment becomes essential for drug delivery. We offer integrated siliconization lines designed to optimize container performance and ensure the highest drug stability.

Key benefits of our automated siliconization:

Superior gliding: increases performance between the glass and internal components, such as rubber stoppers
Reduced dead volume: improves the flow of liquid solutions, ensuring accurate dosing and reducing pharmaceutical waste
Enhanced stability: significantly limits the chemical interaction between the pharmaceutical product and the glass surface
Process versatility: engineered to handle the most common materials, including both silicone emulsions and silicone oils

High-efficiency electrical pre-heating ensures thermal consistency.
Independent delivery systems for each spray nozzle ensure maximum process stability.
High-accuracy volumetric pumps deliver exact and waste-free silicone dosing.
Optimized nozzles and airflows ensure uniform silicone distribution across all internal surfaces.
Flexible annealing lehrs offer electrical or gas heating as an inline or stand-alone unit
