The Impact Of Pet Preform Production Temperature

Gas-assisted products are very common, such as gas-assisted seats, gas-assisted automotive parts, and more. Therefore, gas-assisted injection molding processes are critical products.
When we debug the gas-assisted Pet Preform molding process, there are some factors that should be noted.

For the gas needle panel mold, when the air is pressed into the gas needle, the inlet imbalance is more likely to occur, which will increase the difficulty of debugging. The main phenomenon is shrinkage. In this case, we always check the gas fluency when deflation.

The temperature of the plastic is one of the main factors affecting normal production. The quality of gas-assisted products is very sensitive to plastic temperatures for the following factors. If the plastic in the nozzle is too hot, it can cause burning and silver streaking. Conversely, if the temperature of the plastic in the nozzle is low, cold glue, cold nozzles, and sealed gas needles may be generated. The product always shows shrinkage and silver streaks. What we can do is check if the temperature of the plastic is reasonable. Check that the gas assisted sensor switch is sensitive. Otherwise, it will cause many unnecessary losses.

The pressure of the gas-assisted product remains dependent on the gas. When the product shrinks, we can reduce the plastic to prevent this trend. This always takes measures to reduce the pressure and volume inside the product, so that the gas is more likely to penetrate the thick plastic layer for filling pressure.

China Pet Bottle Creates High Efficiency

Plastic molding is the most important process in creating high quality, durable Pet Preform in modern manufacturing. Because articles made by plastic molding are both strong and economical, it is worthwhile to understand the specific process under this umbrella term.

roll out
Plastic beads, pellets and powder are added to the chamber (extruder) during the extrusion process. The long metal screw in the extruder is continuously agitated and the plastic is liquefied by mechanical friction. The chamber then makes the plastic into the desired end product, which is then transferred to a conveyor belt and cooled with water. Then trim or sand any rough edges on the plastic and finally trim the items. This process is most commonly used to produce simple plastic products such as pipes and sheets, products without various angles and ridges.

Injection molding
Injection molding includes a funnel, a chamber for collecting liquid plastic (where liquid plastic can be injected or liquefied by an external heat source). From here, the plastic is forced into the metal mold under high pressure until no air bubbles remain in the mold. Once completed, the item is allowed to cool before being removed, cleaned, and completed from the mold. This method is best suited for solid plastic products that are more complex in shape than pipes or plates – toys, plastic silverware and automotive parts are examples of products that are best manufactured by injection molding.

Blow molding
Blow molding is similar to injection molding because it uses liquid plastic and metal molds. The difference is that blow molding is designed to make hollow objects, such as water bottles. Instead of being pressed directly into the mold, the plastic is poured into a plastic tube called a parison. The parison is sealed at each end, inserted into the blow tube, and air is forced into the plastic to expand and form the shape of the mold. Once completed, the item is removed and excess plastic sheets (“flash”) are cut from the ends of the parison to produce the finished product.

in conclusion
Using these three processes, plastic can be made into objects that almost anyone might need to use. If you now have the demand for pet prefabrication, then the choice of China Pet Bottle manufacturers can bring you more benefits.

Establish optimal reheat-blowing conditions for Pet Preform
In order to produce a uniform bottle sidewall thickness, the RHB conditions must be properly adjusted. Recommended procedures for establishing optimal conditions:
1. The stretching rod should only be used to center the gate of the preform at the bottom of the bottle; do not use it to obtain the orientation. If the speed of the lever can be adjusted, lower it to the center of the gate. Then increase the speed in very small increments until the gate is centered again. Keep the speed setting.
2. Increase the line speed until a slight pearlescence occurs. Then adjust the temperature of each heater to make the pearlescence uniform. The transparent areas indicate that the preforms are hot at this location; the temperature of these areas should be reduced. After the pearl is even, reduce the line speed to the normal setting.
3. If the machine is operating at maximum speed, a different approach is required. Lower the temperature of the heater until a slight pearlescence occurs; then adjust each heater to make the pearl even. After unification, record the settings. The temperature of each is then increased by the same relative amount. For example, if one heater is set to 80 and the other heater is set to 40, and it is desired to increase by 5%, then they are increased to 84 and 42, respectively. By doing so in small increments, the pearls should disappear in a uniform manner.
4. If the thickness of the side wall of the bottle is not uniform, increase the pre-low pressure and check the uniformity again. If this makes the sidewalls uneven, reduce the pre-low pressure.
5. Once the optimum pre-low pressure is established, it is sometimes possible to make further improvements by adjusting the timing of the pre-low pressure relative to the timing of the stretching rod. Therefore, the pre-flow timing is changed to start earlier and later in the sequence, and the results are evaluated to determine which timing is best.
Note: Pre-low pressure and time have a large effect on the thickness of the shoulder and bottom of the bottle. An increase in both generally increases the thickness of the substrate, and a reduction in both generally increases the thickness of the shoulder.
6. If the uniformity cannot be significantly changed by changing the pre-low pressure and its timing, increase the high-pressure blow delay time. The high pressure may come too fast, so the pre-extraction time will not be given to complete the work.
7. If the change in high pressure delay does not provide the required thickness uniformity, try increasing the stretch rod speed in small increments.
8. As a last resort, change the heater profile. When adjusting the machine, do not change more than one variable at a time. If you change two variables at the same time, one change may improve the uniformity of the sidewalls, while the other may make it worse, and the end result is unchanged. This may lead to a wrong conclusion that neither of these changes has any effect.

The Two Materials For The Production Of Pet Preform

Plastics have thousands of different base chemicals, derivatives and additives that are formulated to cover a wide range of functional and aesthetic properties. To simplify the process of finding the material that best fits a Pet Preform, let’s look at two broad categories of plastics: thermoplastics and thermosets.

Thermoplastics are the most common type of plastic. The main feature that makes them different from thermoset plastics is that they can undergo multiple cycles of melting and curing without significant degradation. Thermoplastics are typically provided in the form of small particles or flakes that are heated and formed into the desired shape by various manufacturing processes. This process is completely reversible because no chemical bonding occurs, which makes it possible to recover, melt and reuse thermoplastics.

Common materials:

Acrylic acid (polymethyl methacrylate)
Acrylonitrile butadiene styrene
Polylactic acid
Polypropylene (polypropylene)
Polyvinyl chloride

Thermoset plastic

Compared to thermoplastics, thermosets (also known as thermosets) remain permanently solid after curing. The polymer in the thermoset material crosslinks during curing caused by heat, light or suitable radiation. This curing process forms an irreversible chemical bond. Thermoset plastics decompose when heated, rather than melting, and do not reform upon cooling. It is impossible to recover the thermosetting material or return the material to its basic composition.

Common materials:

Epoxy resin
Vulcanized rubber

China Pet Bottle Manufacturers Reduce Product Weight

Food, beverages, personal care, home care and pharmaceuticals form key industries in a variety of end-use industries with the largest packaging applications in the Pet Preform market. In addition, other industries have generated a large demand for PET preforms, including agriculture, chemicals and automobiles. The beverage industry is further subdivided into bottled water, carbonated beverages, RTD tea, juices, sports drinks, RTD coffee, alcoholic beverages and other soft drinks. Although the market is expected to maintain steady growth due to the growth of beverage consumption, the improvement of people’s health awareness in developed regions may still hinder market growth. However, demand for PET preforms in developed regions will continue to grow due to continued consumption of bottled water.

The beverage industry remains the key end user with the largest revenue share

According to recent market assessments, the PET preform market is expected to be dominated by the beverage industry for end users. It is estimated that by the end of 2028, the market value of this market segment will exceed 22 billion US dollars, and the compound annual growth rate during the forecast period is 4.4%. However, in terms of growth rate, it is expected that the compound annual growth rate of the food sector will remain around 5.5% during the forecast period. According to reports, the personal care industry will also have a profitable share in the market.

More and more use of ready-to-eat beverages and single-serve beverages in the PET preform market

PET packaging is an economical packaging solution that makes it a clear choice for beverage packaging manufacturers. The growth of the PET preform market is associated with increased consumption of convenient (mobile) food and beverage products in developed and developing countries, such as carbonated soft drinks, RTD tea, coffee and juice. Despite the growing health awareness of consumers in developed countries, the consumption rate of carbonated beverages is still high, and the trend of single-serve beverages is growing. A single RTD coffee did not exist a few years ago, but currently only accounts for more than 30% of total sales in US grocery stores. The single-serve coffee market in the United States has been growing at an alarming rate for several years after the product was launched, and will continue to stimulate US demand for PET preforms in the near future.

China Pet Bottle manufacturers have been focusing on the development of lightweight preforms without compromising quality. Reducing the weight of the preform involves the redesign of the packaging material, which helps the packaging company reduce transportation costs.

China Pet Bottle Manufacturers Are Worth Choosing

In fact, pet preforms have become the preferred product for beverage packaging. With the development of technology, pet bottle machines have many characteristics.

As the popularity of Pet Preform has been highlighted, manufacturing solutions have also demonstrated a typical performance at the forefront.

PET or polyethylene terephthalate bottles are common on the market, especially for beverage bottles and cans. Because it is a non-porous thermoset plastic known for its safety, light weight and recyclability, it is marketable and is highly appreciated by the audience.

Automatically, beverage production companies have increased demand for PET blow molding machines. The reheating technology for producing plastic bottles is still a unique method that many people fear.

Custom designed solutions and products

The uniqueness of the brand has become its unique selling point. Of course, you will want to have an attractive sales figure and continue to grow after production. Therefore, finding a customized solution for the production of PET bottles or cans is the ultimate choice.

Do you want to find a pet prefabricated product that suits you? There are many China Pet Bottle manufacturers available for you to choose from. Among them, Jilian Plastics has attracted more and more people’s attention by virtue of its outstanding advantages. I believe that you will not feel regret when you choose us.

China Pet Bottle Are Favored

Injection blow molding is a very important aspect of the Pet Preform manufacturing process. This process is divided into four steps. Each step contains specific tools and equipment for making plastic bottles.

The first step – the mold cavity

When polyethylene terephthalate is exposed to a relatively strong heat source, it begins to melt into a liquid form. This molten material must then pass through a manufacturing process known as IBM, or injection blow molding.

At this stage of the plastic bottle manufacturing process, molten polyethylene terephthalate is injected directly into the mold cavity. This hole is shaped like a test tube and you may find it in the science classroom. You may also want to know how the top of the screw is created, is this a difficult process. Fortunately, at this stage, the nut is actually molded on top of the tube shape. This shape is itself referred to as a preformed parison.

Step 2 – Transfer to the bottle mold

Once the preform is manufactured, it must be transferred to a second mold. This mold is different from the first one because it is shaped like a bottle to be made. The preformed parison must then be clamped to the second mold. The action of moving a preform from one mold to another can be done manually. However, many companies use machines and equipment that work continuously. By doing so, they do not have to manually move the preform, as this would be very time consuming and cost inefficient.

The third step – the use of compressors

The first thing you should know about blow molding is that it is not based on a new innovation process. This is actually an ancient process that has been used by humans for about two thousand years. It was originally used in the glass blowing process and is still very interesting today.

The type of blow molding we saw in the IBM process was slightly different because it used modern compressors. These compressors should always be a major priority in any factory environment. This is because all different plastic bottle manufacturing processes require injection of compressed air. This is something that only a compressor can produce effectively.

Quality production and service will be the reason for the success of the brand, so there must be efficient machines.

Once a professional finds that the machine is efficient and efficient, another issue of concern is “how to choose the best machine” because it contains many specifications. To bring the best ideas about blower specifications, the blog contains all the basics that help people buy the best blow molding machines, such as:

Pet Preform mold size:

The mold size of the machine is a very important specification, and the professional can decide to produce various products accordingly. In order to produce different types of products, the machine should meet the requirements. Therefore, the professional must obtain the maximum mold size of the machine after viewing the machine specification drawing.

Production capacity:

Professionals must understand how much capacity this machine has for mass production orders. You must know how much it can provide for merchants in a day and a month. In order to meet volume orders in a timely manner, the capacity of the machine should be increased by 25%. For professionals, it is necessary to find out if the machine can produce plastic containers, and then only one person can find out if the machine is good for them.

Machine quality:

The quality of the machine should be good enough to avoid mass production of high quality products and to meet customer goals. On the other hand, the quality of the machine should also be good and does not affect maintenance costs.

Extrusion blow molding process

Blow molding companies may implement extrusion blow molding services that use a manufacturing process that presents hollow plastic stencils that are thin-walled and can be used to hold other materials. This hollow molded plastic product is called blow molding plastic.
Typical products for extrusion blow molding

Typical products formed using this method are items such as milk jugs, water bottles, cosmetic bottles, and many other plastic containers. Large plastic storage boxes and large plastic storage tanks can be manufactured using extrusion blow molding.
What are the steps to create an extrusion blow molded product?

After designing and manufacturing the mold negative according to the precise specifications of the final molded product, a small tube syringe called a parison is fabricated and sealed on a tip end. The parison is placed on the top edge of the closed mold, and then compressed air is blown into the open tip of the parison, which forces the tube to expand and conform to the shape of the surrounding mold. After the plastic has cooled and solidified, the mold can be opened and the finished product can be removed from the mold.
Advantages of extrusion blow molding

There are many advantages to extrusion plastic blow molding. This process not only has no flash, but the blow molded article can also be shaped, or very large or very small. In addition, the blow molding process is inexpensive, precise, and helps to reduce product assembly costs.
How to get an effective blow molding product

You should try to hire the best engineers because the planning and design process can be a complex multi-step process to meet product requirements.

When the mold design is fully finalized, the engineer will work with the finishing team to test the quality assurance. The quality testing process is critical to ensuring that the finished product is operating as intended and designed and that it is in good agreement with the design specifications before mass production begins.

Orders are run on the production line with the approval of the production team and engineers and the approval of the customer.

The key factors for effective extrusion blow molding are collaboration and teamwork. When all team members bring their best to the design and development tables, the final product will meet the needs of customers and end users. Teamwork fosters the highest level of quality and quality, producing the end product you can be proud of. Jilian Plastic Mould is a professional China Pet Bottle company.
