The need for less material and optimisation of transport has also meant that the two companies have retained large sums of money in their accounts.

To get a better understanding of how lightening of preforms can result in advantages for companies, we give several examples, already dealt with in the article вЂњ PET lightweighting: how to safeguard the strength of bottlesвЂќ, which relate to three international brands: San Pellegrino, Coca-Cola, Nokia.Д«y lightweighting its bottles, San Pellegrino has achieved a saving of approximately 850,000 pounds of PET per year and Coca-Cola Company has saved 650 tons. The main factors that cause cost savings and increased gains are: Packaging is one of the main protagonists in all these points and, therefore, the production of PET preforms must be carried out using technologies that guarantee advantages both for companies and for the end consumers of food and beverages.ДЄs well as the advantages for the eco-system already mentioned, it is necessary to stress the economic benefits deriving from new technology applied to the production of PET preforms. It is necessary to market products that show customers the companyвЂ™s commitment to safeguarding the climate, while still maintaining quality and communication standards. Have the lowest possible impact on the environmentД¬ombining ecological sensitivity with the efficiency of industrial processes is what makes the difference today.Give positive sensations for consumers (appearance, consistency, safety).Give a saving in resources during production.This new approach, which is of benefit to companies in the Food & Beverage sector and to all those using PET packaging, would be ineffective if it does not produce containers with characteristics that will satisfy consumers.ДЄs early as the preform design phase it is necessary to take into account the elements that will make the PET container suitable for the company that will be using it. Less use of raw materials and more streamlined logistics are elements that also result in lower expenses, bringing a boost to the company budget. Switching to lighter, smaller packaging means using less PET and this gives a saving in materials, obviously, but also a saving in harmful emissions due to a reduction in the number of transport vehicles in circulation and less voluminous finished products. PET lightening is certainly a considerable step forwards in this regard, and also gives advantages for companies in terms of lower costs and increased earnings. TECHNICAL STUDY: ' How to select PET preform injection moulds'Д¬ompanies in the food sector are increasingly turning towards eco-sustainable practices and, as a result, they are looking for bottling solutions with a lower environmental impact. The technical characteristics of the machines and moulds used to create the preforms are very important, as they determine fundamental aspects such as:ДЄlso, given the level of customisation required by companies in the beverages sector, customisation of the preforms to obtain made-to-measure packaging is increasingly of central importance. The preforms are used both by companies involved in the creation of packaging for third party companies, and by industries that carry out all phases of production in house, from creation of these PET articles to bottling of the end product. In practice, what comes out of the machine is a test-tube shaped object with a threaded, finished neck that is then transformed into a customised container used to distinguish a specific brand. It is normally manufactured using a mould on an injection system, which is subsequently blown into a container for edible or non-edible liquids (water, soft drinks, milk, alcohol, oils, detergents, personal care) on a blowmoulding system. Four or above stages precise temperature PID control for barrel.The preform is an article made of Polyethylene Terephthalate, commonly known as PET.As you will run dozen tons of PET material and heated it up to 190 degree from your in-house temperature. Nano-heating band is also an important part.A support construction is in need to avoid the barrel is getting bended after years running. A longer screw and barrel is need due bigger L/D ratio and adding longer mixing element.Bigger hole of injection nozzle for PET material injection.As most PET bottles require high transparency, high color uniformity, high gloss surface. The mixing element is more complex and very very important.Raw materials will become discolored or opaque due to excessive shear heat. Low shear, low compression ratio screw is a most collection.The Diamer of the Screw is big as the shoot weight is very big comparing to other materials.
