Glass & Packaging Products


To form a vase or a bottle, a series of moulds and fitments are being used, the glass is preformed in the blank moulds, by compressed air(1a) in order to be transferred in the blow moulds where it takes its final form.

A train of equipments is used to form the finish.

All the moulds are manufactured from cast iron and are expendable.

To produce a shape of a bottle for a 8 section machine double gob, the following fitments are required:

  • 22 blow moulds+bottom plates,
  • 30 blank moudls+bufles.

One machine 8 section double gob, produces about 150.000 pieces in 24 hours. Each time a production of a bottle is completed, the line of moulds that were used is being carried to the engine room to be sandblasted (cleaned), repaired and repolished, in order to be ready for the next production.
