Injection blow molding is one of three manufacturing processes used to form hollow plastic into viable finished products. In the injection blow molding process, a manufacturer produces a large quantity of hollow bottles, jars, and a host of other narrow and wide-mounted products. In this case, polymer gets injected onto a core pin, which then rotates to a blow molding station. There, the mold gets inflated and cooled.
The majority of the bottles that are produced are on high speed blow molders. Some of the most common bottles are for juices, carbonated soft drinks, water, energy drinks, dressings, sauces, oils, cleaners and many more. In order to ensure the quality of these products leak testing is performed to check that each bottle will seal and holds pressure.
Although stretch blow molding produces a variety of products, it is best known for the production of PET bottles used for juices, sports drinks, water, and similar products. First introduced in the early part of the 1970s thanks to advanced materials and techniques, it is now what manufactures prefer among the different types of blow molding for making bottles for carbonated beverages.
As part of producing plastic bottles and containers, manufacturers use tests, such as leak testing, to ensure the quality of the bottles surpass the quality parameters. By leak testing bottles, manufacturing companies guarantee a high-quality product that is detected for seal, leaks, necks and capacity to holds pressure. These bottle are tested with precison and continuos motion leak testing to various types of container specifications and quality parameters.
