Blowing MachinesThe manufacture of a product in large quantities, in one shape, and with other identical properties, such as bottles, permits more detailed observation of individual production phases than is possible for other hollow glass ware.

Properties of Glasshape whether formed by hand or by machine. Viscosity and heat transfer are the most important properties involved. Surface tension also plays a significant part in free forming. To a limited extent, expansivity is of concern. This is particularly so in the fabrication of hollow ware where sharp loca

Heat Transmission and Heat Transfer in Formingrol of the rapidly rising viscosity will permit successful production of glass objects of a desired shape at maximum efficiency. This tight coupling of forming and cooling clearly implies the great importance of heat transmission and heat transfer in glass fabrication.

Flow of Glassical glasses used in the manufacture of hollow and flat glass softening (10. poise) starts around 700 °C. With rising temperature the viscosity of glass decreases continuously. A viscosity range from 10. to 10. corresponds to a temperature range from 700 to 1400 °C; that is the viscosity changes ove

Characteristics of Mold Materialsials are exposed to hot, viscous glass in the forming process. Next in importance are requirements on wear, corrosion, working and polishing behavior. Operational conditions (wall strength, external cooling, lubrication, timing etc.) put the stress on one or the other property, while some difference
