Mould Temperature and Heat Flux Measurements and the Control of Heat Transfer During the Production of Glass Containers

Techniques that have been used to measure mould temperatures and heat flow during the production of press-ware and containers are described. Results are presented, which illustrate the effect of changes in important forming variables, such as the temperature of the mould, the pressing pressure and mould lubricants, on the heat transfer. The implication of these results for the control of the heat transfer during the production of glass containers on the IS machine is discussed briefly.

The Glass Container Industry

While many small enterprises are engaged in the production of glass containers, the six largest companies account for an estimated 75% of total output. With research requirements increasing, technological changes rapid, and strong regional and even national distribution organizations required to service the major customers, the larger companies appear to be in the best position to take advantage of the new markets that are developing for glass containers. In the non-returnable bottle, increased requirements for greater strength, lower weight, new designs and colors give the larger firms a decided advantage. The need for sizable investments in new plants and distribution facilities to supply customers at widely dispersed locations also give the major companies an edge. Glass containers encounter keen competition from cans, plastics and other packaging materials. However, cost advantages and the unique characteristics of glass have enabled the industry to surpass the growth of the economy as a whole. Since the turn of the century, glass container sales have increased at an average annual rate of about 5%. During the 1950-1965 period, domestic shipments of glass containers increased 86%, rising from 105 million gross to 196 million gross. Annual per capita consumption during this 15-year period rose from 100 to 146.
