Although the concept of blow molding was considered to have been proposed by the Egyptians between 1700 and 1600 BC, it was reported that this process was first used by Syrians at some point in the first century BC. This is a technique for making a glass bulb at the end of a blow tube that is shaped into the desired hollow shape.
However, American T. Armstrong was considered to have a patent for plastic blow molding technology other than glass in 1851. It was in 1938 that the pioneering experiments and work of two inventors, Enoch Fergren and William Kopick, developed the final industrial application. At the same time, in the mid-1930s, the British company ICI (Imperial Chemical Industries) first developed low density polyethylene (LDPE), which was later commercialized in 1939 and perfected for extrusion in 1945. .
These developments have revolutionized the use of Pet Preform Mould (glass and synthetic based) as packaging materials, which today have become filtered/distilled water, carbonated beverages, milk, edible and non-edible oils, cosmetics, pharmaceuticals (solids and liquids). Form) and a common medium for many other consumer products. This packaging is based on a mechanized (automatic) blow molding machine using PET preforming technology. The fact that the number of soft drink plastic containers in the United States has grown from zero to 10 billion in 22 years (1977-1999) can be assessed by the fact that it has grown! !
In China, some entrepreneurs have achieved remarkable results by designing and developing unique blow molding system models. These ranges include PET stretch blow molding, extrusion blow molding, reheat stretch blow molding (RSBM), and injection stretch blow molding (ISMM) machines. These machines have different bottling capabilities depending on the needs of the end user.
Strict quality control, high standards, competitive prices and delivery, and prompt after-sales service make China Pet Bottle manufacturers more advantageous than their counterparts and competitors around the world. With the global acceptance of PET molding technology as the ideal bottling model, China's molding industry will reach new heights in the next few years.
