PET is an acronym for polyethylene terephthalate – a synthetic resin of thermoplastic polymer. Although the progression in science of polymer was evident from the mid 18th century, the basic material of PET was patented for the first time around a century later in the year 1941. During Word War-2, it became a material of commercial applications right from fabrics to packaging. It was the year 1971 when the first PET bottle was patented.
Interestingly, around the globe, it is referred as a material carrying more popular local brand names, for example, Terylene in the United Kingdom, Lavsan in the once-upon-a- time USSR and polyester in the United States. PET, as a material, has always been in use in the textile industry, but in the contemporary times, it is hugely being used in the bottling industry around the globe. Consequently, the makers of PET blow moulding and hot runner systems have elevated to the occasion. Read more
With the worldwide acceptance of PET (polyethylene terephthalate) as am apt medium for packaging filtered or mineral water, assorted beverages, syrups and sauces, edible oils, cosmetics, items of personal care, detergents etc. the manufacturers of these desire that their products should lure the consumers. Such hopes could become fruitful when the bottles or jars in which they are packed have better shelf life. And this is achieved when high quality preform moulds are used for the PET containers.
There are several factors which denote and determine the quality of the moulds, irrespective of their weight, neck size, range of cavitations and the ultimate applications. To cite an instance, reputed manufacturers like the Delhi NCR based Ashish Tools lay utmost stress on these aspects in the design and manufacture of PET preform hot runner moulds: Read more
Presently, the modes of packaging thousands of edible and non-edible items are based on PET (polyethylene terephthalate) technology in which plastic injection molds give the shape and size of the desired container, be it the bottle or a jar. This is enabled by the hot runner systems that happen to be complex of heated components regulating the injection of the material in the cavities.
The concept of hot runner systems was initially developed during early 60s but gained popularity three decades later. One of the reasons for such delayed implication was the notion about PET containers not being environment friendly until scientists proved that PET is a recyclable material. Above all, the users realised that the hot runner systems are very cost effective and economical in the long run. Read more
In 2014, a leading global market research agency published its findings of a study conducted on the prospects for the Indian PET Preform trade and industry. It projected a highly optimistic market outlook till 2018. During this survey, it was noted that packaging sector is the largest application sector for the plastic industry, representing almost 60 percent of the total plastics demand. The forecast on consumption of plastics in this segment indicated a mammoth figure of 10 million tonnes by the year 2020.
Indeed, these signs have spelt a boon for the manufacturers of Injection Moulding Machine that is extensively used in PET bottling and allied products. Many of the companies engaged in this industry have created a global impact too. To cite an instance, the Delhi NCR-based Ashish Tools has geared up to meet the challenges of the future. Keeping in view these aspects, it has already setup a unit where mould Base are mould Inserts are assembled in dust proof environment. The range of machinery at this plant includes latest CNC systems from reputed international brands like DMG, Mori Seiki & BFW.
