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 important for everyone.
In 1867 , Frederick Siemens introduced a technical innovation to accelerate the industrial production of glass bottles and jars.(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.(an engineering masterpiece) .
This machine process was suction and impact method to produce glass bottles. The glass piece was sucked into a metal mold and was cut automatically.
In 1952, two engineers named Ingle and Smith patented the IS machine. In this machine, the Press & Press method was used to produce glass bottles .This method is still used today.
First, the molten gob is blown into a mold and the body is shaped .Then it is transferred to the next mold for final shaping and its ring is also made 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 andconserve energy resources.
