Glass and glass products are one of the most important industries in the world. The diversity of glass products, the exclusiveness of some of these products, and their numerous and ever-increasing demand have made this industry vital for everyone.
In 1867 , Frederick Siemens introduced a technical innovation to accelerate the industrial production of glass bottles and jars: the continuous tank furnace. These tank furnaces are still used today.
Also, in 1903 an American named Michael Jay invented an automatic glass bottle production machine, considered an engineering masterpiece.
This machine utilized a suction and impact method to produce glass bottles. A piece of glass was drawn into a metal mold and cut automatically.
In 1925, two engineers named Ingle and Smith patented the IS machine, which used the Press Blow method to produce glass bottles. This method is still employed today.
First, the molten gob is blown into a mold to shape the body. Then it is transferred to a second mold for final shaping, with the ring formed by blowing again.
In the second half of the 20th century, we have often seen the introduction of electrical control devices that increase production volume.
New process to produce lighter glasses, Narrow Neck Press & Blow ( NNPB), help preserve the environment and conserve energy resources.
