Syringe forming lines

Purpose-built equipment to manufacture customized syringes, integrating several techniques to ensure the highest container quality

Producing syringes with custom dimensions and shape

Syringes are complex products that require an extremely precise forming process: Stevanato Group syringe manufacturing lines include several specifications, which are normally optional, such as servomotors for controlling the most critical manufacturing phases (cone forming, total length) and flow meters for automatically regulating the burners.

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
6. NEEDLE ASSEMBLY	Our equipment is geared towards ensuring ease of use, low footprint, and energy saving

Siliconization

Siliconization is a critical parameter that influences the container performance: it 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 a lubricant that favors and improves the glideability of syringes.

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.

Needle assembly line siliconization

Optimizing control of the process and its reliability through precise automation, siliconization lines are designed to:

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

Features

Pre-heating with electrical heating System;

Independent delivery system for each spray nozzle;

Volumetric pumps for silicone dosing accuracy;

Silicone spray nozzle and air flows to uniformly spread the silicone along the internal surface of the glass product;

Baking lehr with electrical or gas heating system. The baking lehr can be installed on the siliconization line or be an independent unit, depending on the type of silicone used.
