Manufacturing Of Pet Bottle Preform

The production of Pet Bottle Preform is carried out in stages. Typically, plastic bottles for drinking water and other beverages are made of polyethylene terephthalate (PET) because the material is both strong and light. In order to understand the manufacturing process, it is helpful to first check the composition of the PET and its effect on the plastic bottle.

PET is a thermoplastic polymer that can be either opaque or transparent, depending on the specific material composition. Like most plastics, PET is produced from petroleum hydrocarbons by the reaction between ethylene glycol and terephthalic acid. To produce plastic bottles, PET is first polymerized to produce long molecular chains.

Polymerization itself can be a complex process and leads to many inconsistencies between one batch of manufactured PET and another batch of manufactured PET. Usually, two impurities are produced during the polymerization: diethylene glycol and acetaldehyde. Although the yield of diethylene glycol is generally not high enough to affect PET, acetaldehyde can be produced not only during the polymerization process, but also during the bottle manufacturing process. The large amount of acetaldehyde used in the manufacture of bottles in PET imparts a strange taste to the interior of the beverage.

Once the plastic itself is manufactured, the bottle manufacturing process can begin. To ensure that the PET is suitable for use, extensive testing was performed after manufacture to check if the bottle was not penetrated by carbon dioxide (this is important for bottles with soda). Other factors, such as transparency, gloss, chip resistance, thickness and pressure resistance, were also carefully monitored.

Pet Preform Manufacturers Should Make Products With Care

When referring to Pet Preform Mould and tools, it is thought of the parts produced by processes such as blow molding or injection molding.

These components can be used for many different purposes in different fields and industries, and the proper use of them for the first time is extremely important to the success of any process they will be used for.


The mold is a hollowed out block that is used to set the shape of the product being manufactured. It can be made of different materials, the most common of which are aluminum, steel, alloys and copper. It also has different components.

These components include pins, bases, tappets, ejector, guides, bushings, and alignment devices.

Because the mold shapes the final product, it is always important to use the right type. Manufacturers should thoroughly understand the final product to be produced. Otherwise, the entire chain - from the smallest part to the role they play - will be sacrificed.

Injection molding

Since you have a better understanding of the role of the mold in the production process, you can better understand what injection molding is.

Injection molding, as the name suggests, is to inject any kind of material into the mold. In this process, different materials can be used, from metal to polymer, from glass to elastomer.

Basically, the material is fed into a heated bucket where it is mixed and forced into the middle of the mold. From here, the material hardens as it cools, forming the final product.

Blow molding

Blow molding is used to produce hollow plastic parts. It can be done in three different ways: injection blow molding, injection stretch blow molding, and extrusion blow molding.

Basically, the process requires air to blow plastic material into the mold. From here, the plastic cools down to form the final product.

Tool work

Tools include finding and getting the different parts and machinery needed to produce a product. It covers many categories, the most common of which are fixtures, fixtures, gauges, molds, molds, cutting patterns and equipment.

The process of instrumentalization is not just about choosing what is out of the box or what others are using.

Pet Preform Manufacturers remember that the results of the process directly affect the quality of the final product and the cost of the entire process. Because of this, you need to be extra careful if you are responsible for this process.

PET is one of the few thermoplastics that can be upgraded by SSP treatment to achieve a similar resin quality. Today, post-consumer bottle flakes have been successfully used in food contact packaging, high IV strapping and filaments. Recycling between bottles and bottles requires the highest standards of purification. This will facilitate the recycling of Pet Bottle Preform and is also very advantageous for the development of pet bottle preforms in the market.

Due to its advantageous properties, PET (polyethylene terephthalate) is a successful example for food contact packaging. But it also caused more PET waste, which in turn caused public interest in the issue. Recycling contributes a lot to the positive impression of PET packaging: it raises ecological awareness and triggers the collection and recycling of post-consumer waste. In addition, major brand owners are keeping up with the trend, promoting low carbon footprints and resource savings.

Become part of the solution
It is expected that the consumption of PET bottles worldwide will double in the next decade. Even assuming a high collection rate, most of the PET waste will eventually be landfilled. Cleaning and processing PET bottles is a valuable secondary resource. In this case, consumers are responsible for contributing to the recycling process and welcome products containing rPET content - the bottles are made into fibers, filaments and nonwovens, sheets, tying materials and, most importantly, Become a bottle again.

The flexibility of modular design:
The production waste of preforms, bottles and sheets and the sheets in post-consumer waste can be recycled into granules or processed into finished products on-line. PET sheets are cleaned, IV increased, either independently or online. In combination with a circulating extruder and pelletizing system, an optional upstream or downstream vacuum SSP reactor ensures outstanding rPET quality. Online applications combine energy savings and value added.

Pet Bottle Preform Production Points

The PET chemical name is polyethylene terephthalate, also known as polyester. Currently, this material is used most in the customer and is 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 becomes 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.
Injection molding machine selection

Since PET has a short settling time and a high melting point after melting point, it is necessary to use an injection system with more temperature control portion and less self-friction heat in the plasticizing process, and the actual weight of the product (aqueous gate material) cannot be Less than 2 / 3 of the injection capacity of the injection molding machine.

PET (also abbreviated as PETE) is an abbreviation for polyethylene terephthalate and is the chemical name for polyester.

PET is a transparent, strong, lightweight plastic that is widely used to package foods and beverages, especially for convenient size soft drinks, juices and water. Almost all single and 2 liter bottled carbonated soft drinks and water sold in the United States are made from Pet Bottle Preform.

It is also popular for packaging salad dressings, peanut butter, cooking oils, mouthwashes, shampoos, hand sanitizers, window cleaners, and even tennis balls. Special grades of PET are used to carry the food container home and the prepared food tray, which can be heated in an oven or microwave oven.

The basic building blocks of PET are ethylene glycol and terephthalic acid, which combine to form a polymer chain. The obtained spaghetti-like PET fibers were extruded, rapidly cooled, and cut into small particles. The resin pellets are then heated to a molten liquid which can be easily extruded or molded into articles of virtually any shape.

Due to the unique nature of PET, it is rapidly becoming the preferred packaging material for food and beverages in the world. Like glass, it is a very strong inert material that does not react with food, resists microbial attack, and does not biodegrade. But unlike glass, PET is very lightweight, easy to transport, efficient, and not fragile.

Pet Bottle Preform Blow Molding Guide

The plastic world is very complicated. There are too many different processes that can be used to make plastic packaging, and one of the most popular methods of mass producing Pet Bottle Preform is by blow molding. Currently, there are three different forms of blow molding: extrusion blow molding, injection blow molding, and stretch blow molding. There are multiple reasons why any company chooses these two methods. confused? Take a look at our different types of blow molding beginner's guides below to help you learn more.

What is blow molding?
Simply put, blow molding is a method of mass production of plastic containers by specialized blow molding machines. The blow molding process begins by simply melting the plastic and making it into a parison, which is a hollow tube. The parison is then injected into the machine where the process is different.

Extrusion blow molding
For this process, the plastic is melted and then the blank is extruded. The parison is then closed and the air is blown into the desired shape while it is still hot. Then, once the workpiece is completely cooled, the plastic is ejected. Extrusion blow molding has two parts: continuous and intermittent. Continuous means that the parison is continuously extruded, and each piece of plastic is cut by a knife. Intermittent means that there is a stopping point between each mold.

Extrusion blow molding is usually chosen because of its fast production speed and ability to produce complex parts.

Injection blow molding
Injection blow molding involves injecting a plastic or polymer into a core pin and then rotating the core pin through a blow molding machine until the plastic expands into the desired shape. Then cool and squirt in a simple process. However, since this is a relatively slow process, injection blow molding is the least used of the three blow molding techniques.

Stretch blow molding
This process is a bit more complicated than other processes. It uses a small plastic resin that is stretched vertically and then stretched horizontally to give the molecule a cross shape. Molecular hybridization produces higher quality plastics by increasing the barrier strength and preventing stomata. Since blow molding machines limit the design of certain bottles, this option is often chosen for small batch orders.

Blow molding does not have to be a complicated process. Choosing a professional manufacturer can give you more peace of mind. Jilian Plastic has a full range of products, from 5-Gallon Pet Preform to other small parts, I believe that we will never let you down!

Plastics are the most common materials for end-use parts and products, from consumer products to medical devices. Plastics are a versatile material with thousands of polymer choices, each with its own special mechanical properties.

Plastic manufacturing processes have been developed to cover a wide range of applications and part geometries. For any designer and engineer involved in product Pet Preform development, it is critical to be familiar with the manufacturing options available today and foreseeing new developments in the way parts are manufactured in the future.

When choosing a manufacturing process for your product, consider the following factors:

Form: Does your part have complex internal features or strict tolerance requirements? Depending on the geometry of the design, manufacturing options may be limited, or they may require extensive manufacturing design (DMM) optimization to make their production more economical.

Volume/Cost: What is the total or annual volume of the parts you plan to manufacture? Some manufacturing processes have high upfront costs in terms of processing and installation, but the parts produced are very cheap. In contrast, low-capacity processes have lower startup costs, but due to slower cycle times, lower automation, and manual labor, the cost per component remains the same or only slightly decreases as capacity increases.

Lead time: How long do you need to produce parts? Some processes produce the first parts in 24 hours, and some high-volume production processes take months to process and install.

Material: What pressure and pressure does your product need to withstand? The best material for a given application is determined by many factors. Cost must be balanced with functional and aesthetic requirements. Consider the ideal characteristics of your particular application and compare it to the choices available in a given manufacturing process.
Plastic type

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 given part or product, 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.

Pet Preform blow molding design and manufacturing considerations

According to the engineer, blow molding or extrusion blow molding is the manufacturing process for making hollow thermoplastics. When completed in the split cavity, air pressure is applied to the heated plastic material, commonly referred to as a parison.

This process causes the material to swell, similar to a balloon. As the material expands, it presses against the walls of the mold cavity, causing the material to form. There are many blow molding manufacturers and blow molding companies; it is important to choose a company carefully.
Advantages of extrusion blow molding:

No flash
Size from very small to very large
Cheaper mold
Good dimensional accuracy
Reduce assembly costs

Concentrated design considerations:

When the blow molding project is completed, the wall thickness should always be uniform to facilitate rapid molding cycle times. In these projects, sharp corners should be avoided as much as possible, and the draft angle should always be vertical when the mold is opened in the correct direction. Finally, the thickness of the body wall should not exceed 2:1.
