![]() There are certain factors crucial for the process selection these include tool prices, overall capital expenditure and the number of available performs, etc. Whereas, the remaining 15-20% were manufactured where either process is an option. com), out of which nearly 80% were utilized for beverages and commonly manufactured using the two-stage technology. In this regard, it is important to know that the world consumed over 580 billion plastic bottles in 2021(Statista. Generally, blow molding processes are characterized by a number of stages involved in the process (i.e., single-stage and double-stage, etc.) the choice is usually based on the type of product/application. The "cold preform method" derives its name from the requirement to chill preform prior to actually reheating and stretching.įigure 3: PET Two-Stage Automatic Blow Molding Machine How Two-Stage Molding is better than One-Stage When they arrive, they are unscrambled, reheated with infrared light, and conditioned before molding. The preform will typically include the bottle's neck including and its threads also, it can be transferred to a third - party vendor before being inflated out using second machine. In the first machine, the plastic is injected into a totally cooled preform before being delivered to the second device. The injection molding method and stretch blow molding machine are examples of these. Two machines are utilized in the two-stage injection extension blow molding procedure. The raw material is injected from the hopper into the injection screw the plate spins preform to the blow/stretch blow terminal with its own heat, and with no heating up for blowing the product then rotates to the release station and drops down it is completely automated circulation working method. There are three stations on the machines: injection way to strengthen, stretch or blow, and product. You will certainly not be disappointed.Figure 1: Working of One-Stage Pet Molding Machine If you are a PET producer and you are looking for a modern machine, we recommend you buy the SMF machine. SMF is a recommended distributor of modern machines. The semi-finished product is heated and then formed into the desired shape. PET bottles are made from ‘PET preforms’ using modern blow moulding machines. Interestingly, all machines are made in Poland and sold in as many as 80 countries! SMF’s innovative two-stage blow moulding machines make it possible to significantly speed up the production of PET bottles, while maintaining high product. If you are looking for the right blowing machine for your business, we suggest you purchase modern equipment for PET bottle production from SMF. As soon as the bottle receives its final shape, it is automatically transferred to the filling machine using air conveyors. Their work speeds up the production process. Two-stage blow moulding machines are certainly worth a try. What kind of blow moulding machines are worth buying? Therefore, it is a good idea to fit your factory with modern blow moulding machines that will be able to create the most innovative PET bottle shapes. A decent blow moulding furnace can produce between 2,000 and 30,000 packs or bottles in an hour, which is really some impressive performance. Interestingly, the mass then enters the so-called capper in the blow moulding machine, where the blowing process takes place and the bottle gains its final shape.īlow-moulding machines are a great type of equipment, enabling a much quicker manufacture of PET bottles. It is heated to a high temperature, roughly 260-300☌, and then becomes a liquid mass. They are produced by processing a semi-finished product known as ‘PET preform’. PET bottles are used on a daily basis, but few people are aware of how they are made. The most important advantage of this material is that it can be recycled and reused. PET bottles are also characterised by mechanical strength, which is very important when filling. ![]() PET packaging is comparatively easier to transport thanks to its simple design. First of all, PET bottles are soft and light they are much safer to transport than glass. There is no denying that the popularity of these bottles is the result of their unquestionable advantages. This material is quite resistant to acids, fats and other similar substances, so it is very often used in the food industry. ![]() ![]() PET comes in granules which must be processed before they can be turned into a product such as a bottle. ![]() This material was invented in Great Britain in 1941 and is now used in the textile and glassware industry. PET stands for ‘polyethylene terephthalate’ and it is a kind of plastic. What is the production process of such bottles? Are specialised machines used for it? Read on to find out more! PET – what is that? It is used primarily to transport and store beverages. The PET bottle represents a very popular form of packaging, available not only in Poland but also worldwide. ![]()
