What is PET Preform Mold?
It is an important mold used to make PET (polyethylene terephthalate) preforms and is widely used in the production of plastic products. PET preform molds are key components in the manufacture of plastic bottles, containers and other plastic products. They have the advantages of light weight, durability and high transparency, so they are widely used in industries such as food, beverage, medical and cosmetics.
What are the structures and components of PET Preform Mold?
The structure of PET Preform Mold is complex and delicate, and it consists of several key parts. The first is the mold shell, which is the shell of the entire mold, providing basic support and protection. This shell must be strong and rigid enough to withstand the forces of the high-pressure injection molding process.
Next comes the mold core and mold cavity, which are the core parts of the mold. The mold core is used to form the part of the bottle neck and inner cavity, while the mold cavity is used to form the outer shape of the bottle body. These two parts are usually made of high hardness steel to ensure the durability and precision of the mold.
In addition to mold core and mold cavity, PET Preform Mold also includes some other components. For example, a cooling system is essential to control the temperature of the mold to ensure that the plastic material can fully solidify and solidify. The nozzle part is used to inject molten plastic material, while the ejector pin is used to form the bottle neck and thread.
In addition, the mold may also include some auxiliary components, such as guide posts, core pullers and ejectors. The role of these parts is to ensure the smooth operation of the mold and assist the mold to complete complex operations during the injection molding process.
What are the types of PET Preform Mold?
injection mold
This is one of the most common and widely used types of plastic bottle molds. Injection Molding Molten plastic material is injected into the mold by an injection molding machine to form the shape of the preform. Injection molds can produce plastic bottles of various shapes and capacities to meet the needs of different industries and applications.
extrusion mold
Extrusion dies are suitable for the production of plastic bottles with longer shapes, such as tubular containers or specially shaped bottles. The extrusion die molds the desired bottle shape by extruding molten plastic material. Extrusion dies are widely used in the production of plastic bottles, providing us with more diverse choices.
blow mold
Blow molding molds are suitable for the production of hollow plastic bottles, such as mineral water bottles and beverage bottles. Fully automatic blow molding molds are formed by extruding molten plastic material and then blowing it into a hollow shape by air pressure. Blow molding molds enable efficient production and consistent quality and are widely used in the plastic bottle industry.
rotary mold
Rotary molds are special molds used to produce plastic bottles with rotated or twisted shapes. Through the rotating mechanism inside the mold, the plastic material can be molded into bottles with complex shapes, such as twisted bottles, twist cap bottles, etc. The application of rotary mold brings greater creativity and diversity to the design of plastic bottles.
In addition, there are multi-cavity molds and single-cavity molds. The multi-cavity mold can produce multiple plastic bottles of the same shape at the same time, improving production efficiency. The single-cavity mold is suitable for small batch production or special-shaped plastic bottle needs.
What are the advantages of PET Preform Mold?
High precision and reliability
They are designed and manufactured with precision to ensure consistency in the shape and size of the preform. Whether it is the shape of the neck, the body or the mouth of the bottle, it can be accurately copied and shaped. This precision guarantees the quality and performance of the final product, making plastic bottles more stable and reliable in use.
Efficient production capacity
Due to the rational design and optimization of its structure, the mold can achieve fast and efficient production during the injection molding process. The injection molding machine quickly injects molten plastic material through the mold to form the shape of the prefabricated blank, and completes the cooling and solidification process in a short time. This high-efficiency production capacity greatly improves production efficiency and meets the needs of mass production.
Flexibility and variety
The design of the mold can be adjusted and changed according to the needs to adapt to the production of plastic bottles of different types and specifications. This flexibility enables the mold to adapt to changes in market demand and meet the individual needs of customers. Whether it is shape, capacity or function, PET Preform Mold can provide a variety of options to meet the needs of different industries and applications.
Built to last and dependable
The mold is usually made of high hardness steel, which has good wear resistance and corrosion resistance. This durability allows the mold to withstand repeated use in the high-pressure injection molding process, reducing the frequency of repairs and replacements and lowering production costs.
What are the market demands for PET Preform Mold?
beverage industry

How to repair and maintain PET Preform Mold?
First, regular cleaning is the key to keeping your PET Preform Mold in good condition. Using appropriate cleaners and tools, thoroughly clean all parts of the mold, especially the core and cavity. Keeping the mold clean prevents the accumulation of impurities and residues and ensures a smooth injection molding process.
Attention to lubrication is also an important aspect of PET Preform Mold maintenance. Before and during use, apply an appropriate lubricant to the moving parts of the mold, such as ejector pins, guide posts, and sliders. This reduces friction and wear, prolongs the life of the tooling and ensures smooth operation of the tooling.
In addition, regular inspection and maintenance are also essential. Regular inspection of all parts of the mold, including the mold shell, cooling system and auxiliary components, etc., to ensure its integrity and proper functioning. If damage, wear or other problems are found, repair and replace them in time to prevent further expansion of the problem.
In addition, it is also important to pay attention to the environmental and storage conditions of the mold. Keep molds in a dry, clean storage environment away from moisture, dust or corrosive substances. At the same time, when the mold is out of service, it should be properly packaged and stored to prevent collision and damage.
