How Do Pet Bottle Preform Have A Bigger Market?

Pet Bottle Preform seem to be invisible objects in life, everyone is used to it, but pet bottle preform production is a big science for pet bottle manufacturers, constantly doing market all year round. By analyzing and investigating continuous innovation and design, we can have a bigger market and have the possibility to lead the market.

What are the specific conditions for the production of pet bottle preforms?

The first is the consumer’s habits, the habit of using is humanized design, easy to design on the take and belt.

The second is to satisfy the consumer’s vision. We can often find out that in fact, the current popularity is to popularize what used to be called obsolete in the past few years. The pet bottle is also the same trend, and there is a fixed trend. road.

The third is the most basic quality. The quality of the product determines the market of the product. The quality determines the brand of the product. The quality is still determined by the raw materials and production process.

The production threshold of pet bottles is very low, but the requirements, technology and market share are the most worthwhile aspects of manufacturers; I believe that in the near future, Pet Bottle Mould will break through the current dilemma and continue to move forward.

Features Of One Stretch Blow Molding Pet Bottle Preform

What is the molding method for high temperature resistant PET bottles?

One stretch blow molding. Heat the stretch blow mold to 100~180°C, then place the reheated Pet Bottle Preform in the stretch blow mold, perform a stretch blow molding, and hold for a few seconds or more than ten seconds to make the product crystallization. After the mold. The one-shot stretch blow molding method has the following characteristics:

1The equipment layout is simple, the floor space is small, and the heating equipment and cooling container of the stretch blow mold can be added to the original molding equipment (the number of cooling containers can be determined according to the production status), and the PET bottle can be finished. Warm disposal.

2 Directly heat on the Pet Bottle Mould, heat treatment, and the heat loss is small.

3 The one-time stretch blow molding method uses a low treatment temperature and a low degree of crystallization of the product, and the acceptable hot filling temperature is lower than that of the secondary stretch blow molding.

4 Although it is a one-time stretch blow molding and heating treatment, the product still needs to be cooled and disposed, and the total molding time is extended.

The Performance Of Pet Bottle Preform

PET chemical name is polyethylene terephthalate, also known as PET, mainly used to produce Pet Bottle Preform.

PET has better rheological properties in the molten state, and the effect of pressure on viscosity is greater than temperature. Therefore, the fluidity of the melt is mainly changed by the pressure.

Since PET macromolecules contain lipid groups and have a certain hydrophilicity, the particles are sensitive to water at high temperatures. When the moisture content exceeds the limit, the molecular weight of PET decreases during processing, and the product is colored and brittle. In this case, the material must be dried prior to processing at a drying temperature of 150 ° C for more than 4 hours, typically 170 ° C for 4-6 hours. The air injection method can be used to verify that the material is completely dry.

The proportion of recycled materials should generally not exceed 25%, and the recycled materials should be thoroughly dried.

Since PET has a short settling time and a high melting point after melting point, it is necessary to use an injection system having more temperature control portions and less self-friction heat during plasticization, and the actual weight of the product (aqueous injection material) Can not be less than 2/3 of the injection capacity of the injection molding machine.

How To Plan The Design Of Pet Bottle Preform

At the beginning of the planning of Pet Bottle Preform, planners need to conduct market research, clear customer needs, learn from the same industry in the same industry, understand the molding equipment and production technology level of the company, and establish the concept of the beginning of the planned products.
PET bottles need to have the function of maintaining the contents. PET bottles can prevent moisture, water, dust, corrosion, external dust, water and other liquid substances; avoid packaging contamination and corrosion; avoid ultraviolet rays Penetration, customary environmental temperature changes, maintenance of packaging from the sun and ultraviolet rays. PET bottles need to have the effect of accepting external forces. It can be used to a variety of shipping methods and storage methods to maintain the contents without damage.
PET bottles should have a satisfactory stiffness and a beautiful shape. The most common shapes of PET bottles are round, square, oval, etc. From the point of view of view, they each have their own advantages and disadvantages. The round PET bottle has a high rigidity, but the shape is not beautiful. The square PET bottle has a beautiful appearance, but it is not easy to control the uniform thickness of the PET bottle during molding. Elliptical PET bottles have higher rigidity, but the manufacturing cost of pet Pet Bottle Mould is higher. Therefore, in order to ensure the rigidity of PET bottles, in addition to selecting high-strength materials, the shape of PET bottles is also planned to enhance the rigidity of PET bottles. And load resistance.
PET bottles make the products display their functions. PET bottles can be beautifully displayed, bright colors, bright appearance and transparency, showing the product’s display function, attracting customers and inspiring customers’ desire to purchase. PET bottles should have the function of convenient use. The bottle mouth planning of PET bottles should be considered to be open and convenient, and can be opened and closed repeatedly. It is convenient to dump the contents, and the phenomenon of spattering and hurting people cannot occur.

Reasonable Design Of Pet Bottle Preform

Pet Bottle Preform are designed with affirmative essentials and principles to be designed, designed according to the affirmative essentials, with effective application and design concepts to ensure the performance advantages in the application.

Most of the bottoms of pet bottle preforms have a convex bottom or flat bottom double rounded layout, because the bottom of the bottom of the bottle protrudes from the bottom of the bottle to form an arch hole, which can increase the internal pressure resistance of the bottle body and cover the bottle body of the factory. The stability. At the time of injection molding, pet collapse can be restrained and the thickness of the bottom of the bottle can be symmetrical, and the flat bottom double-round bottom layout is mostly used for large-volume pet bottles, which can better absorb the pressure from the inside of the bottle. The growth of the shape and size tends to be the shape of the thread at the neck of the small and medium pet injection blow molding. The original trapezoidal thread (single head) grows to a semicircular long thread.

The condition of the bottle mouth thread is mainly due to the good compatibility with the bottle cap. The moisture resistance performance depends to a large extent on the common precision of the bottle mouth and the bottle cap. Here, is the sealing performance of the reaction bottle mouth good or bad? important part.

After the pet bottle is loaded, the capping machine with adjustable torque can be accepted to screw the cap. The torque can be extracted according to the diameter of the cap according to the relevant scale. The combination of the size of the bottle and the lid is an important prerequisite for moisture and vapor barrier, and the precision of the screw cap is the key to the moisture resistance.

In order to ensure the safety of use, it is necessary to improve the sealing of the bottle mouth at the beginning and increase the moisture resistance. The wall of the bottle is too thin to be blow molded and has low strength. Usually, it is required that the wall thickness of the other parts is uniform and the thickness of the bottle is larger than the thickness of the bottle. However, for the factory to improve the isolation and strength of the pet bottle, the bottle thickness design value range of 1.5 ~ 2mm, the current thickness tends to grow thicker.

Injection Molded Pet Bottle Mould

Injection molded Pet Bottle Mould are a tool for producing plastic products; they are also tools for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in mass production of complex parts of certain shapes. Specifically, the material that is melted by heat is injected into the cavity by high pressure, and after solidification by cooling, a molded article is obtained.
According to the molding characteristics, the injection mold is divided into two types: thermosetting plastic mold and thermoplastic plastic mold; according to the molding process, it is divided into plastic mold, blow mold, casting mold, thermoforming mold, hot stamping mold (compression molding), injection mold, etc. The hot stamping die can be divided into three types: overflow type, semi-overflow type and non-overflow type. The injection mold can be divided into two types: cold runner mold and hot runner mold; Can be divided into mobile, fixed two.
The temperature in the injection mold is uneven at each point and is also related to the time point in the injection cycle. The role of the mold temperature machine is to keep the temperature constant between 2 min and 2 max, which means that the temperature difference is prevented from fluctuating up and down in the production process or gap. The following control methods are suitable for controlling the temperature of the mold: controlling the fluid temperature is the most common method, and the control accuracy can meet most of the requirements. Using this control method, the temperature displayed in the controller and the mold temperature are not uniform; the temperature fluctuation of the mold is quite large, because the thermal factors affecting the mold are not directly measured and compensated for these factors including the injection cycle change, injection speed, melting temperature and Room temperature. The second is the direct control of the mold temperature. The method is to install a temperature sensor inside the mold, which is adopted when the mold temperature control accuracy requirement is relatively high. The main features of mold temperature control include: the temperature set by the controller is consistent with the mold temperature; the thermal factors affecting the mold can be directly measured and compensated. Typically, mold temperature stability is better than by controlling fluid temperature. In addition, mold temperature control is more reproducible in production process control. The third is joint control. Joint control is a combination of the above methods that simultaneously controls the temperature of the fluid and the mold. In joint control, the position of the temperature sensor in the mold is extremely important. When placing the temperature sensor, the shape, structure, and position of the cooling passage must be considered. In addition, the temperature sensor should be placed where the quality of the molded part is decisive. There are many ways to connect one or more mold temperature machines to the injection molding machine controller. It is best to use a digital interface from the standpoint of operability, reliability and immunity.
