Sometimes, Machine vendors describe North American-based bottle blow molders as a justly conservative lot, glad to stick with their accustomed injection blow presses and hydraulic shuttles. In the meantime, more effective fully electric alternates have become very popular inside Europe and are rising in Asia and other regions. But the sales figures indicate that American blow molders are eventually welcoming all-electric machinery. An Auburn-based plastic fabrication company's official stated that we had had great success with every all-electric molding machine, and that is all we will purchase from now on. So the plastic fabrication company found it logical to find similar effective enhancements in fully electric blow molding. Its initial step was to buy all-electric blow molding machinery from all-electric molding machines dealers. The experience of that Auburn-based plastic fabrication company with that machine over the past year and a half has made it emphasizes all-electric blow molding machines. Turning The Tide The Auburn-based plastic fabrication company is a pioneer of all electrics on the coasts. Interviews with three major suppliers of all-electric injection blow and extrusion blow machines in North America indicate that approximately six such pieces of machinery are situated in North America. The other few are delivering or are on order. The vice president of sales of a Michigan-based machining manufacturer states that most local extrusion blow molding machines seem content with conventional hydraulic pieces of machinery. The modular platform of that machining manufacturer permits electric servos or hydraulics on the identical basic press. The Michigan-based machining manufacturer has supplied all-electric blow molding machines but has not promoted them very hard in the North American continent until recent times. This Michigan-based machining manufacturer launched its first electric blow molding machine that employs local parts like controls, actuators, and servo motors. After displaying at the show, the Michigan-based machining maker operated its electric blow molding machine for two thousand hours to carry out an engineering assessment. This month, the machinery is moving to the plant of an American customer to begin commercial production. According to the vice president of sales of a Michigan-based machining manufacturer, a customer's motivation is partially a requirement for extra capacity, partial inquisitiveness to examine something new, and partly a wish to establish a business partnership with the Michigan machining manufacturer. The vice president of sales of the Michigan-based machining manufacturer states that power savings are not a reason compelling American blow molders to carry investment in fully electric machines. The real advantage, he says, is greater repeatability and accuracy. European blow molders, he states, were more open to newly introduced technology as the electric utility expenses are much greater there. He said in Europe that more than fifty percent of the shuttle machinery sales are fully electric. The vice president of sales of a German fully electric blow molding machine manufacturer's North American branch states that the sales of electric blow molding machines are slowly rising in North America. He stated that bottle manufacturers had had sufficient capacity in recent times, and therefore they have been hostile to capital expenditure, apart from those few that were increasing capacity. Benefits Of Fully Electric Molding Machines The vice president of sales of the German fully electric blow molding machine manufacturer's North American branch agrees that the higher electric expenses have made businesses accept electric blow molding machines in Europe. He states that the sales of full-electric blow molding machines are rising in China because of their faster cycles and power savings. In China, the vice president of sales of the German fully electric blow molding machine manufacturer's branch in North America sees a weather change. He states a couple of fully electric blow molding machines are working in North America, more are being shipped, and two are being ordered. He anticipates that the electric blow molding machine sales will double as bigger companies will give ten orders of electric blow molding machines in the next year. Although power cost is seven to ten percent of the cost of the bottle, the major benefit in the local market is repeatability and accuracy. The vice president of sales of the German fully electric blow molding machine maker's branch in North America also states that dry machine cycles are fifty percent speedy with new electric blow molding machines. Their entire processes are at least ten percent faster. The Auburn-based plastic fabrication company anticipates increasing energy efficiency by launching more fully electric blow molding machines to injection and blow molding departments. Its official expects its energy efficiency to enhance as it uses more fully electric injection molding and blows molding machines. That official believes it would be challenging for the Auburn-based plastic fabrication company to justify buying the fully electric blow molding machine on energy cost reductions. The savings will come from decreased upkeep downtime and better quality components due to enhanced machinery accuracy. Anticipation Of Auburn-Based Plastic Fabrication Company Sometimes, Machine vendors describe North American-based bottle blow molders as a justly conservative lot. Because they are glad to stick with their accustomed injection blow presses and hydraulic shuttles.
Manufacturing industries as they introduced us to PET blow molding technology, and since then, the world has had a 180-degree shift. However, technology hasn’t always given us good things, but blow molding is so far the best technological addition to the world in recent times. With time new improvements are being made in the field of PET blow molding; the technology has enhanced to the point that it is now cutting down the production cost to an exceptional degree. Thus, these innovations in PET blow molding have taken the world by storm, and we think this technology has come here to stay forever. The benefits of PET blow molding were already outstanding, but with constant innovations and improvements that are being made in this field, the benefits have increased to such an extent that it seems unreal. PET blow molding was known for its exceptional features, including precision manufacturing, design accuracy, reduced production cost, time-saving, requiring no manual input, energy-saving, etc. Let’s have a look at the recent innovations that have been made in the field of PET blow molding technology. •Light Weighting Light weighting is an amazing innovation that has significantly helped in reducing the production cost. It is basically a process in which the amount of PET that is usually used to manufacture a plastic product is reduced to half; this way, the compressed air pressure used to blow the PET is also decreased. Decreased compressed air pressure enables energy savings meaning the PET blow molding process saves up tremendous amounts of energy while manufacturing the same high-quality plastic products, innovative! Right? For instance, a plastic bottle earlier weighed around 12 g to 14 g, and the compressed air pressure used to blow them was between 365 psi to 590 psi. However, with this light-weighting technique, a plastic bottle can now weigh around 8 g, and the amount of compressed air pressure needed to blow it has also been decreased. Weight reduced, compressed air pressure requirement decreased, and energy saved only through light-weighting technique. •Recirculating High-Pressure Compressed Air The use of compressed air in PET blow molding contributes a great amount to the production cost of PET blow molding products. For this reason, an innovation of compressed air recovery systems was made in the field of PET blow molding that has solved the problem. Now the compressed air used in PET blow molding is recycled, which also aids energy savings in this process. The high-pressure compressed air that we recycle in the PET blow molding processes can be used as recirculated compressed air in other PET blow molding processes. Recirculated compressed air is ideal for producing service and pre-blow air. Apart from this, it can also be returned to low pressure compressed air network of the plant. It is not only helping in saving compressed air but is also enabling money savings and energy savings. •Separate Low-Pressure And High-Pressure Air Systems The PET blow molding technology is a fast process and has the ability to blow around 2400 plastic bottles per hour. This is seen as a benefit, but there is a flaw to it; fast processing causes pressure drops in filters and headers, which are responsible for supplying compressed air to the machine. To solve this problem, the compressed air systems are set to run at a higher level which in turn decreases the compressed air pressure for other machines. Thus, all-electric blow molding machines sellers came up with a solution and did some innovation in the design of blow molds. They separated the high pressure and low pressure compressed air systems first. Along with that, they put localized air receivers and pneumatic components to cope with the pressure drop and minimize it as much as possible. The size of the pneumatic components should be accurate; the receiver must be set close to the moulder; the piping has to be large to deal with spikes. That’s innovative and has made PET blow molding technology the most commonly used technology in the world. •Place Sub-Micronic Filters Cleanliness is mandatory for carrying out the PET blow molding process effectively; anything that isn’t meant to be there, like water vapours, particulate matter, or oil, is going to cause some problem. Therefore, to stop any such problem from happening, two sub-micronic filters are placed at a place from where high-pressure compressed air comes into the machine. This way, cleanliness is maintained; however, the machine also uses six pneumatic valves that are also required to remain clean without accumulation of oil or particulate matter as it disturbs the supply of compressed air, which directly impacts the shape of the final product.
It is done by a technique called the Blow molding technique. It is a technique in which the plastics are melted and are extruded into a hollow tube. The pressure is exerted to form them into the shape of the container using the pp bottle-making machines. It has been famous for years as it is a technique used worldwide to produce containers in the form of these plastic bottles made up of fantastic finishes at very affordable prices. This method is also famous because it provides the most efficient and the most cost-effective way of producing high volumes of containers for packaging. Why Use Blow Molding? Various factors describe why blow molding had been used so much. Some of these factors are: •Higher Rates Of Production These Blow molding machines have a faster cycle compared to other manufacturing processes. •Easy Molding Of Complex Parts It is a helpful process when it is about handling complex and challenging shapes, even if they are asymmetrical and irregular, it is famous to handle them well. •Cost-Effective Method This production method is comparatively cheaper in the long run than the other methods of production as it works more efficiently and effectively, playing a good role in the production process. Types Of Blow Molding Methods To Select From Although the general purpose of these blow molding machines is to create hollow objects, like bottles or packaging, by applying pressure that forces the material into a mold cavity, which gives the object a hollow shape. If one plans to use the method of blow molding, one must be familiar with the types of blow molding and what they are used for. The main and common types of blow molding processes are known as: Extrusion Blow Molding (EBM) In this process, the resin is heated and extruded to form parison, a vertical tube-like piece of plastic that allows compressed air to pass through. The two-part mold is used and closes at the parison at both ends. As soon as the mold is sealed, the blow pin is inserted into the neck of the bottle, and the air is blown into it. The pressure of the air causes the parison to take the shape of the mold. Including the threads in the neck portion of the mold. Mold is cooled, and the parison's bottom is cut, letting the mold open. The bottom of the parison is cut, and the bottle is placed over the conveyer belt. This process is used to manufacture •large-size, High-Density Polyethylene (HDPE) •Low-Density Polyethylene (LDPE) •Polypropylene (PP) bottles with large necks Compression Blow Molding (CBM) It is a special kind of extrusion molding in which the blow pin blows air into the parison, so the plastic takes the shape of the bottle; it also uses physical pressure to shape the neck area of the bottle. It is used in manufacturing bottles made with HDPE, LDPE, and PP resin and can quickly achieve critical neck dimensions. Injection Blow Molding (IBM) In this molding process, the heated resin is injected into the mold using a screw. This injected plastic is molded into the shape of mold then the air is used to blow the shape into the mold. The mold is allowed to cool down. The bottle is placed over the conveyor belt once ejected from the mold. They are used in the production of HDPE, LDPE, and PP bottles with a small to medium blowup ratio. Injection Stretch Blow Molding (ISBM) In this process, the resin is heated and is injected into the machine using a long screw. This injected plastic is then molded into the shape.
Blow molding refers to a molding procedure that the production industry employs to manufacture hollow objects composed of plastic. Selecting the appropriate plastic material for any blow molding process can be challenging. Strength, flexibility, density, cost, and more factors help decide which plastic material is suitable for blow molding. The blow molding capabilities expand to vast and small parts using multiple or single molds, including blow pin and air needle models. The exact blow molding techniques employed for a particular project depend on the design's desired physical attributes and complexity. Here is an outline of the drawbacks, benefits, and characteristics of plastic materials used in blow molding. High-density Polyethylene (HDPE) High-density Polyethylene is the first-ranked plastic of the world and the most frequently blow-molded plastic resin. This is because of its desirable physical qualities, high strength to density ratio, temperature resistance, and chemical resistance. High-density Polyethylene is employed in an extensive range of products, including consumer liquid bottles such as motor oil and shampoo, industrial drums, carrying cases, play structures, and coolers. It is molder-friendly, easily colored, chemically inert, and easily colored. The Food and Drug Administration has approved high-density Polyethylene, the safest plastic. A PP bottle-making machine helps consumer bottle manufacturers manufacture consumer liquid bottles with blow-molded high-density Polyethylene. Low-Density Polyethylene Versions of low-density Polyethylene encompass ethyl-vinyl-acetate and linear-low. Manufacturers employ low-density Polyethylene for softer items that require a high degree of flexibility or stress crack resistance. Usually, the higher the ethyl-vinyl-acetate content, the weaker the molded component is. Typical applications of low-density Polyethylene encompass boat fenders, traffic channelizers, and squeeze bottles. Low-density Polyethylene is also easily colored, translucent, chemically inert, and molder friendly. Polypropylene Polypropylene is the second-ranked plastic in the world- it's a very famous injection molding material. Polypropylene is like high-density Polyethylene, but its slightly lower and stiffer density benefits. Manufacturers commonly use polypropylene in elevated temperate uses like medical components and dishwater tubes that need autoclave sterilization. It is molder-friendly, quickly colored, and translucent. Polyvinyl Chloride(PVC) Even though polyvinyl chloride is the third-ranked plastic of the world, Polyvinyl chloride has been intensely examined for utilizing lead and cadmium as stabilizers. It releases hydrochloric acids while processing and releases remaining vinyl chloride monomers following molding(most of these problems have been decreased). Polyvinyl chloride is translucent. It comes in soft and rigid forms- the soft material. Manufacturers usually use the soft version of polyvinyl chloride in blow molding. Typical use includes traffic cones, bellows, and delicate medical components. Acrylonitrile Butadiene Styrene (ABS) Acrylonitrile Butadiene Styrene is comparatively hard plastic. This ABS plastic is employed for injection molding football helmets. Blow molding standard Acrylonitrile Butadiene Styrene is usually colored for use and clear in small appliances and electronics housings. After drying, Acrylonitrile Butadiene Styrene molds well. Nevertheless, the chemical resistance of components composed of Acrylonitrile Butadiene Styrene is not like the chemical resistance of polypropylene. Therefore caution should be employed in using this plastic with ingredients exposed to chemicals. Polyamides/Nylon(PA) Nylon melts rapidly; therefore, manufacturers commonly utilize it in injection molding. The materials employed for extrusion blow molding are usually versions of nylon four to six, nylon six to six, nylon eleven, and nylon six. Nylon is an affordably priced translucent material that poses decent resistance to chemicals and gives a good performance in highly heated environments. Manufacturers use nylon to manufacture reservoirs and tubes in automobile engine compartments. Polyethylene Terephthalate (PET) Polyester Polyethylene Terephthalate is usually injection blow molded inside clear containers. Whereas it is possible to extrusion blow mold polyethylene terephthalate, it is less commonly done, as this plastic material needs to be extensively dried. The biggest market for polyethylene terephthalate is for water bottles and soft drinks. Co-polyester And Polyester Manufacturers frequently employ polyester in making fiber. Unlike Polyethylene Terephthalate, manufacturers can do extrusion blow molding of modified polyesters such as co-polyester and Polyethylene Terephthalate glycol. Sometimes, co-polyester is employed to replace polycarbonate inside container products. It is like polycarbonate, but it is not that strict or precise, and it does not comprise bisphenol A, a substance that, according to some research, causes health problems. Polyurethane and Urethane Urethanes have performance qualities that are popular in coverings such as paint. Generally, the elasticity of urethanes is greater than the elasticity of polyurethanes, which need to be formulated especially for becoming thermoplastic urethanes. The thermoplastic standards can be injection or extrusion and cast blow molded. This is most frequently utilized as a single layer in multiple-layer blow molding. Thermoplastic Elastomers Manufacturers use thermoplastic elastomers for replacing natural rubber inside molded components. This material is explicit and can be colored (usually black). Automobile manufacturers mainly utilize TPEs in grip surfaces, air intake ducts, bellows, and automotive suspension covers. After drying, it molds and usually reprocesses well.
Blow molding technology has become the most widely used method worldwide for the precision and efficiency that it provides in each and every product. The infinite number of benefits that it has offered to almost every industry is what has led to its popularity globally. Today almost every product of either simple or complex shape is being produced by the use of blow molding technology. With the rise in population, there has been a great rise in the demand for products, but the supply of products has never been able to meet it as better as it has with the use of blow molding technology. Therefore, the success of blow molding technology is evident from its worldwide application in all the different fields and industries. Benefits Of Blow Molding Technology •One benefit of blow molding technology that will always remain top of the chart is its precision. Never has another technology has been able to provide such precision in every product like blow molding technology. Thus, the precision of blow molding is exceptional and unmatchable. •Mass production of products is what industries have to do, but any other method or technology used to take up a lot of time. Whereas blow molding technology does the same thing in a fraction of time than traditional methods took and even does it better. •The cost of labor and all the other things was a lot in all of the methods that were being used before blow molding technology. However, blow molding is comparatively exceptionally low cost; neither does it require a lot of labor nor does it waste any raw material. •It was a hell of a task to make products of complex shapes and designs before blow molding technology, but after the advent of it, it has become so easy to make any product of any shape. Blow Molding Technology – One Process, 3 Variants There are three processes of blow molding technology that are being used worldwide; all the methods are equally efficient and highly productive. The processes are almost the same entirely; there are just a few steps that make one process different from the other process. •Extrusion Blow Molding In extrusion blow molding, the raw material is melted and turned into a molten liquid first. It is then poured into a mold that is made according to the shape of the product that one desires to make. Once the parison is poured into the mold, the air is blown in its center to inflate it. Once the parison has been inflated into the shape of the mold, it is set aside to cool down with the mold. The final product is revealed when the parison has cooled down and solidified and is ready to be taken out of the mold. High-quality extrusion blow molding machines are being used to carry out the process efficiently. •Injection Blow Molding In injection blow molding, the only difference is that the molten liquid that is parison is not poured but injected into the mold with an injection-like machine. The raw material is also not inflated onto the same station but is taken to the other station, where it is inflated into its shape by a machine. •Stretch Blow Molding In stretch blow molding, the only difference is that the raw material isn’t inflated but instead stretched into the shape of the desired product.
