China Pet Bottle Chooses Jilian Mold

Very people are very strange to the word Pet Preform. Although this product is not common in us, it can bring us a lot of benefits, such as the plastic bottles we usually see and so on. A product is closely related. It can be said that there is no such product. Many of the equipments we use today cannot be used normally. What are the functional characteristics of this product?

The functional characteristics of the PET preform is that the material is tough, but the toughness is good. Therefore, the manufacturing process is more and more convenient, and it can be molded better. The customer’s need for style can also be well received. The second feature is that the surface is smooth, looks very beautiful, and is an environmentally friendly product, and will not release some toxic gases.

The functional feature is that the material is soft and the function of high temperature resistance is good. Therefore, the requirements for processing are not very high, so it is natural and convenient for the processing workshop, so that there is some cost. The decline, and the natural value of the products we send to them is also quite large.

What is the use of PET preforms?

PET preforms may not be known to many people. They are originally intermediates of processed products. After the process of blowing, it can cause some products that are usually used in our daily life, such as plastic bottles. What is the use of an intermediate? We should be familiar with this issue.

The use of PET preforms is still very important. The use of one can be used as an intermediate. After being made, it can be better viewed. If there are unpleasant places, it can be easily corrected, and it will not become a waste after completion. The use of the second is that the manufacturing is relatively easy to control, and it is very good to send the mold to us, so that the effect is better for the manufacture of the seat. The use of three is that the raw material of this product is usually compared with simple processing, so the use for us is to reduce the cost of work, of course, it can also reduce the workload, in the mold, the natural can be better invested in the inspection of the manufacturing side, and Can reduce some mistakes, so as to better protect the benefits of our seat.

China Pet Bottle Is Your Success Choice

  1. Pet Preformhave uniform wall thickness and the most concentrated part of consumers’ attention. The printed appearance should be flat and continuous; if the liquid PET preform contains handles, grooves, ribs, etc.
  2. The printing surface of the PET preform should be designed so that it cannot cause inconvenience to the printing operation. The label surface should be flat. A “sash” can be designed on the surface of the PET preform to accurately position the label.

    3. When the appearance of the PET preform is marked, no movement occurs, such as the middle of the PET preform is relatively thin,

    4. Change the appearance of the PET preform and increase the circumferential groove or rib of the appearance of the PET preform to improve the rigidity and bending resistance of the PET preform. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of the PET preform under temporary load.

    If the material is high density polyethylene or polypropylene,

    5. When designing extruded PET preforms, the cross section of PET preforms should be rectangular or elliptical. For low density polyethylene or other flexible PET preforms, the cross section is round, which is convenient for content. The material was extruded from the PET preform.

    6. When blow molding, it tends to be hardened first. Therefore, the wall thickness of this part is also larger. At the edge and the corner, the final contact of the parison is inflated, and the wall thickness of the portion is small. Therefore, the edges and horns of the PET preform should be designed to be rounded.

Trustworthy China Pet Bottle

Pet Preform come in a variety of sizes, shapes and colors. They range from opaque to translucent or transparent, so different measurement techniques are required depending on the type of sample.

Opaque pet preforms are opaque and are preferably measured using a diffuse d/8 ball reflector.

Translucent preforms allow light to pass through, but only diffuse, so it is not possible to clearly distinguish objects on the other side. Both the reflection and transmission measurement modes work well depending on the translucency of the sample. Based on experience,

– If your customer will view the path length of the sample, you can see the slight detail of the thumb or finger through the preform, and then the transmission is the preferred method of measurement.

– If you don’t see the details, the reflection is preferred.

The path length is defined as the thickness of the sample from the point where the light enters the sample to the thickness of the sample.

Transparent preforms allow light to pass through with little or no interruption or distortion so that objects on the other side can be clearly seen. These pet preforms can only be measured using a gearbox gauge.

Chinese Pet Bottles Have Rich Experience

The hollow blow molding of the Pet Preform is to insert the tubular PET which is still softened from the extruder into the molded pet preform mold, and then pass the compressed air, and use the pressure of the air to make the along the cavity. The deformation is thereby blown into a hollow product having a short neck opening. Hollow blow molding has been widely used to produce a variety of thin shell hollow products, chemical and daily packaging containers, as well as children’s toys.
Hollow blow molding (also known as blow molding) is a method of inflating a hot-melt shaped embryo closed in a mold by means of gas pressure to form a hollow product, and is a third common PET processing method, and is also developing rapidly. A PET molding method.
The mold for blow molding has only a female mold (female mold). Compared with injection molding, the equipment has lower cost, strong adaptability, good formability (such as low stress), and can be formed with complex undulating curves (shapes). product.

Blow Molding Process Of Pet Preform

Multi-layer blow molding process
Multi-layer blow molding is the use of several plastics to make a multi-layer composite Pet Preform in a suitable manner and then formed by a general blow molding process.
Multi-layer blow molding is mainly to meet the higher demand for plastic packaging containers such as barrier properties, flame retardancy, weather resistance, heat insulation, internal and external dichroism, etc. for cosmetics, pharmaceuticals and foods.
For example, a double-layer blow molded bottle with an outer layer of PVC and an inner layer of PE, the outer layer of PVC provides good barrier properties, rigidity, flame retardancy and weather resistance, while the inner layer PE makes the bottle non-toxic to the package. Excellent chemical resistance.
Typical applications for multilayer blow molded articles are the packaging of milk, natural juices, tea, ketchup, carbonated soft drinks (CSD) and beer.
Multi-layer extrusion blow molding refers to the plastic preforms of different kinds of plastics after being plasticized by a plurality of extruders, and then formed into a billet layer which is layered and tightly bonded together by a special machine head, and then fed into a blow mold. A technique for inflating a multi-layer hollow article.
This blow molding technology is developed on the basis of single-layer extrusion blow molding. The molding process is almost the same as that of single-layer extrusion blow molding, except that the molding equipment uses multiple extruders to plasticize different types of plastics. The machine head used should be able to extrude the tubular structure of the multi-layer structure, and the three-layer tube blank extrusion equipment

Injection stretch blow molding process
Stretch blow molding: a blow molding process by biaxially oriented stretching, which is divided into a one-step injection drawing process and a two-step injection drawing process.
One-step method: hot pet preform method
Pet preforms, stretching, and blow molding are done in one machine. Pet preforms are semi-finished products in the production process.
The combination of devices is:
1 consists of an extruder and a blow molding machine;
2 consists of an injection machine and a blow molding machine.
Two-step method: cold pet preform method
After the pet preform is cooled, the cold pet preform is reheated for stretching and blow molding. Including injection of preforms for stretch-blow molding of pet preforms; extrusion of pet preforms by directional stretch blow molding.
There are currently four combinations of stretch blow molding:
1-step extrusion stretch blow molding for processing PVC;
2 two-step extrusion stretch blow molding for processing PVC phase PP;
3 one-step injection stretch blow molding for processing PET and RPVC;
4 two-step injection stretch blow molding for processing PET.
Blow molding materials: PAN, PET, PVC, PP, etc.
01. Injecting pet preforms into a directional stretch blow molding process
The bottomed pet preform is first injection molded and continuously sent to a heating furnace (infrared or electric heating) by a conveyor belt (or a rotating belt), heated to a stretching temperature, and then incorporated into a blow mold by means of a stretching rod. Stretched and then inflated. It is necessary to control the appropriate stretching temperature, and it can be molded by multi-cavity (2-8), and the production capacity can reach 250-2400 per hour (capacity is 340-1800g beverage bottle).
02. Extrusion pet preform blank oriented blow molding process
The plastic is first extruded into a tube and cut into a length to serve as a cold billet. Put it into the heating furnace and heat it to the stretching temperature, then take the heated pet preform from the furnace to the molding table through the conveying device, so that one end of the pet preform forms a bottle neck and a thread, and the pet preform is along the axis. After pulling 1.0-1.3 times, the blow mold was closed for inflation molding.
Another method is to take out the heated pet preform from the furnace, stretch it in the axial direction of the tube in the stretching device, and send it to the blow mold. The mold inflates the stretched pet preform and inflates it. Forming and trimming waste edges. The production capacity of this method can reach 3,000 bottles per hour and the capacity is one liter.
Applications: PET beverage bottles, PP bottles, PC bottles
