Vials Forming Lines - Stevanato Group
search img


Vial forming from glass tubes is a manufacturing process laden with numerous challenges, due to the stringent needs of the pharmaceutical packaging industry.

Thanks to its consolidated experience as a glass forming machine manufacturer, Spami – a Stevanato Group brand – designs its vial lines with an emphasis on all forming phases: glass tube feeding, the glass forming process (heating, neck and shoulder forming, cutting, bottom forming), transport, annealing and packing.

On-going technological improvements and the synergistic cooperation with Ompi – a sister division specialised in primary packaging of 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.

As a result, Spami lines are able to produce containers that satisfy the needs of the most demanding pharmaceutical companies in terms of mechanical resistance, cosmetic and dimensional requirements and, consequently, high reliability during the filling, capping and crimping phases, and other operations.

Stevanato Group vial 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.

Since all the machines operate with the highest mechanical precision and feature easy-to-use HMIs, they ensure seamless high-speed production, fewer rejects, mechanical resistance, and vials conforming to cosmetic and dimensional standards, making them the best solution to preserve drug integrity.

Vial forming lines come in a variety of specifications that vary depending on the production requirements. By maintaining close ties with the customer throughout every step of the process, the Stevanato Group is able to design and manufacture fully custom-made, purpose-built equipment capable of producing vials with entirely custom dimensions and shape.


Vial forming line capable of increasing production, reducing maintenance, improving efficiency and simplifying cleaning activities



The 3BS30 is a high-speed forming machine, ideal for the production of large batches. It has 30 upper chucks for neck forming and 20 lower chucks for bottom forming (10 on each side).

It processes glass tubes up to a diameter of 40 mm, producing 2 vials with each index movement at a maximum mechanical speed of 45 index movements (90 pcs/minute).


  • Tube size: STD Ø 31 mm (available up to Ø 40 mm)
  • Vials per cycle: 2
  • Max mechanical speed: 45 index movements/minute

Space requirements

  • Dimensions: 3.2 x 2.2 m
  • Weight: 8,100 kg


3BS30 EV

The 3BS30 EV is a state-of-the-art vial forming machine equipped with servo motors to control the most critical operations of the forming process.

With its 12 bottom forming stations, enhanced process stability and ease of use, it can work at a maximum mechanical speed of 54 index movements (theoretical speed of 108 pcs/minute).


  • Tube size: STD Ø 34 mm (available up to Ø 40 mm)
  • Vials per cycle: 2
  • Max mechanical speed: 54 index movements/minute - 12 lower chucks

Technical data

  • Dimensions: 3.2 x 2.2 m
  • Weight: 8,100 kg


BZ16 and BZ EV

The BZ16 is a highly flexible machine, ideal for the production of small-medium batches of standard and non-standard vials. It has 16 upper chucks for neck forming and 10 lower chucks for bottom forming. It produces one vial for each index cycle.

BZ EV is the high-speed version of the machine equipped with servomotors, it can operate at up to 60 index movements/minute.


  • Tube size: up to Ø 50 mm;
  • Vials per cycle: 1;
  • Max mechanical speed: 40 index movements.


Weight: 4,500 kg


Double BZ

The BZ is a new concept of vial forming line, composed of 2 single-exit forming machines combined in a single line.


  • Increased efficiency in terms of speed;
  • Increased flexibility: it combines the high speed deriving from the 2 machines with the flexibility of the BZ 16;
  • It is able to produce large amounts of vials at high speed;
  • Allows for performing job change/maintenance activities on one machine, while the other is still running



The H3S is the latest development in vial forming machines, managing a 50% increase in output (theoretical speed of 180 pcs/minute) coupled with a significant reduction in the changeover time.

Thanks to its 3 exits, it is the most highly performing vertical vial forming line available on the market. The servomotors that drive each one of the 30 lower chucks ensure greater control of the process.



The HS Line is the brand new vial forming line that embodies a great technological leap for forming machines:

  • 50% increase in production within the same small footprint of the former equipment (180 pcs per minute)
  • No-glass-to-glass automatic tube loader from pallet
  • Reduced format changeover time (2 to 3 hours depending on the format)
  • Reduced product contamination and easier cleaning
  • Simplified maintenance
  • Non-contact inspection systems
  • New-generation handling system (low-maintenance robot)
