How To Choose A Pet Bottle Preform Container

Pet barrel factory thought that pet barrels are more and more popular. Therefore, the selection of pet buckets becomes an important one, and it is important to choose the right pet bucket. Pet barrels are generally made by molding, and the molding methods are different, which often have a great impact on the performance and cost of the products.

The pet bucket factory reminds you that it is appropriate to have a rough understanding of the various forming methods when selecting a Pet Bottle Preform container. The characteristics of various pets commonly used in pet packaging containers are very important for the correct selection of pet packaging containers. Due to the raw materials of pet packaging containers, the basic characteristics of pet packaging containers are determined. Pet packaging containers of the same or similar form may have extremely large differences in performance depending on the raw materials. Polycarbonate blow molded bottles and general polyester stretch blow molded bottles have extremely good transparency and gloss, which are very similar in appearance, but polycarbonate bottles have excellent high temperature resistance but poor insulation properties. The general polyester stretch blow molding bottle has good insulation performance, but the heat resistance is poor.

 For the incoming filling, the cover and the product supported by the barrel should be inspected first, otherwise the lid and the barrel will not match, which will easily lead to liquid leakage. During the process, please do not drag the bucket directly on the ground to avoid bottom wear and scratches. The correct way is to lift your hands or ship them from the forklift pallet. Pay attention to the filling, the liquid temperature can't be higher than 70 degrees, and the loading and transporting temperature should not exceed 25 degrees. It is forbidden to fill the PET tank and load it in high temperature liquid immediately after loading. It should also be stored in a clean, dry place to prevent contamination inside the barrel and avoid direct exposure to the sun.

 The pet barrel used should be lubricated inside and outside, no welding and seamless, and light weight, good strength, impact resistance, corrosion resistance, non-toxic and tasteless, and transportation is also very convenient.


Its heat acceptance scale is generally within the range of minus 40 degrees to 60 degrees. If this temperature is exceeded, the pet barrel will be deformed and even cracked. Therefore, we must ensure that the temperature does not exceed this scale when we use it. If we must exceed this temperature, we need to do some precautions. First, the surface quality of the pet barrel is required to be qualified, and there must be no markings, pores, and whitening. Fog, black spots, discoloration, luster and other defects, so the planning of raw materials, equipment, molds, and even products throughout the injection process must pay attention. Secondly, because Tongming pet has high melting point and poor fluidity, in order to ensure the surface quality of the product, the process parameters such as machine height temperature, injection pressure and injection speed are finely adjusted, so that the PET can be filled with the mold without being produced. Internal stress causes deformation and cracking of the product.

   In addition, pet barrels must have certain strength and wear resistance, and can withstand impact, heat-resistant parts, chemical resistance, water absorption.

The 5-Gallon Pet Preform designed by Jilian Plastics are of good quality, and we also offer a range of other pet packaging products. If you have this demand, then we are definitely your best. Choice, so come and consult us, I believe we will not let you down.

Identify The Pet Bottle Preform Is Good Or Bad

1. First taste, Pet Bottle Preform tastes different from ordinary plastic, burn it with a lighter, and then smell very aromatic and comfortable (just burn a bottle to smell). If PET contains other ingredients, the taste is very pungent. . There is a bottle containing SEBS ingredients that cannot be used.

2, look at the burning part, if the distribution of black or oil droplets is very fast, most of the melting point is not normal, which is often found in PET film.

3, drawing, when burning, pull the wire on the lighter, see the length of the wire is not long, then pull the pulled wire off, see the break point in the middle, the wire is not rolled into a small circle, the more the volume More indicates that the melting point is high.

However, if it is a bottle, it should not be a big problem. The most critical point is to distinguish whether it contains PVC, which is a fatal injury to PET. First sample more, then tiling in a sunny place, PVC is light blue in the sun. If there is a white crease in the fold. The above is the naked eye identification, the accuracy is limited, mainly depends on experience.

There is also a more practical and better way to buy an oven to adjust the temperature to 250 degrees and bake it for half an hour. If the product contains PVC, there will be a lot of yellow spots on the surface; if the melting point is not enough, it will be very fast. melt.

In fact, PET also includes many varieties, such as PET smashed film from foreign factories, slurry blocks, and film rolls less than 30 cm in length, all of which have different customer groups.

The identification of these goods is strongly required to be tested with an oven. In particular, PET reels are a very scarce source of supply throughout the market, generally 80 to 120 cm in length, and the film thickness of 3-5 filaments is very high (white transparent).

As a professional manufacturer of pet products, Jilian Plastics provides a wide range of products, and we can bring you satisfactory products with our professional technology. Our 5-Gallon Pet Preform have been favored and loved by many customers in the market, and you are welcome to contact us with this demand. 

Pet Bottle Preform Advanced Control System

1, the robot
The station with cooling station removes the board from the side, effectively increasing the cooling of the Pet Bottle Preform. The use of linear guides not only ensures the movement of the robot, but also provides a convenient maintenance space. Modular built-in preform conveyor belt design makes maintenance easier.

The Siemens servo control system used can be effectively integrated with the PLC control of the entire system, which makes the system more stable and more convenient to operate. The 96-cavity robot uses a dual-drive, dual-rail design that significantly increases load carrying capacity and speed of movement, helping to shorten the molding cycle.

2. Advanced control system
Through cooperation with the production process of PET preforms, the system can not only achieve closed-loop control of injection speed and holding pressure, but also adopt management modes with different levels and different management rights, ensuring that all advanced settings must be It can be accessed by administrative authority, which effectively controls the quality of the product. Management and operation are made easier by integrating the drying system with the control system of the injection molding machine.

3. Unique hydraulic control system
The hydraulic system uses the variable pump control technology and accumulator method of *. The perfect combination of variable pump and accumulator makes control more stable, easy and fast, and is more energy efficient. The entire hydraulic system uses original components from Germany, high-performance pumps and valve units to make the entire hydraulic system more stable and stable. In addition, in hydraulic design, a company follows all the principles of valve parts and oil slabs as close as possible to the operating components such as cylinders, making control faster and *.

4. Connection between the bottle preform machine and the bottle blowing machine: When connecting the bottle preform machine and the bottle blowing machine, the following items should also be noted:
<1> Before the connection, the preform must be cooled to room temperature, and the temperature of the inner and outer walls is the same.
<2> The connection should minimize the drop point and avoid defects such as bruises and scratches on the preform.
<3> Try to avoid corners and collisions.
<4> Add a cooling device such as a fan. If possible, * use a conveyor belt with a breathable function.
<5> There must be sufficient delivery length to allow the preform to get enough cooling. Generally, the lightweight preform has a wall thickness close to 2.0 mm, which is cooled faster than a normal preform, so the theoretical conveying distance should not exceed 30 m.
<6> The speed of the conveyor line should be moderate, so that the preforms should not be stacked or too fast.
<7> The ambient temperature should be appropriate. If the ambient temperature is too high, consider providing a blower to supply cold air.
<8> Considering that the subsequent equipment may be shut down, it is also necessary to add a set of embryo device, so that the preform can be directly attached to the embryo while being transported to the conveyor belt.
