Unlocking the Mysteries of Extrusion Pelletizing Technology
The relationship between screw size and extruder machine
The size of the screw in an extruder is a critical factor in determining the throughput capacity and melting rate of the system. The screw diameter is measured in outside diameter and is typically between 0.75-10 inches, with popular sizes including 1.5″, 2.5″, 3.5″, 4.5″, and 6″.
The effective length of the extruder, typically 24-36 L/D, is the ratio of the length over the diameter of the screw.
The influence of screw design on extruders
The design of a screw in an extruder is crucial for achieving the desired output and product quality. The design parameters include the flight depth, channel width, helix angle, and number of flights. The flight depth determines the amount of material that can be conveyed, while the channel width determines the residence time of the material in the extruder.
The helix angle affects the shear rate and mixing efficiency, while the number of flights affects the conveying capacity and compression ratio.
What materials are the screws made of?
- W6Mo5Cr4V2 (commonly known as HSS), which is a high-speed steel material with excellent wear resistance and toughness.
- 38CrMoAlA, which is a type of nitrided steel with good wear resistance, corrosion resistance, and high-temperature strength.
- 9Cr18MoV, which is a type of stainless steel material with high hardness, wear resistance, and corrosion resistance.
- GH113, which is a type of superalloy material with excellent high-temperature strength, corrosion resistance, and wear resistance.
- SKD61, which is a type of hot-work die steel with high toughness, wear resistance, and heat resistance.
The relationship between the raw material and the extrusion system
The material being extruded and the extruder itself have a significant impact on the extrusion process. Material properties such as viscosity, density, and melt flow rate need to be carefully considered when selecting an extruder and designing the screw.
For example, high-viscosity materials require screws with a larger pitch and deeper channels to ensure adequate conveying and mixing. On the other hand, low-viscosity materials may require a shorter pitch and shallower channels to prevent over-shearing and degradation
The FAQs About PET Pelletizing line
If I want to recycle PET, should I choose single screw or twin screw extruder?
PET extruders can be single or twin screw. Single screw extruders are usually used for the production of low viscosity PET, while twin-screw extruders are suitable for high viscosity PET. The choice of extruder depends on the characteristics of the PET product to be produced and the production efficiency.
What are the specific applications of high-viscosity PET and low-viscosity PET?
High-viscosity PET: used in the manufacture of bottles such as mineral water bottles, beverage bottles, cosmetic bottles, bottles for cleaning products, etc. High viscosity PET is also used for the production of fibres such as clothing, home textiles, technical textiles, etc.
Low-viscosity PET: used in the manufacture of various films, such as packaging films, cling films, plastic bags, coating films, etc. In addition, low-viscosity PET is used for the manufacture of optical materials such as optical films and reflective films.
How do I choose the material for the screw?
The choice of material for the screw depends on various factors, such as the type of polymer being processed, the processing conditions, the required output, and the budget. It is recommended to consult with a materials expert or a supplier to determine the most suitable material for a specific application. In general, higher-end materials such as W6Mo5Cr4V2A may offer better wear resistance and durability, but they also come with a higher price tag. Lower-cost materials like 38CrMoA1A may be suitable for certain applications but may require more frequent replacement due to wear and tear.
What is the required power supply for your PET extrusion pelletizing system?
Our PET extruder pelletizing system require a three-phase power supply of 380V/50Hz or 220V/60Hz or 480V/50Hz, depending on the power supply requirements of your plant.
What is the optimal temperature range for PET extrusion and pelletizing?
The optimal temperature range for PET extrusion and pelletizing typically falls between 240-280℃, although it can vary based on the specific material and processing conditions.

Plastic pelletizing system: the comprehensive guide
As plastic manufacturing companies continue to expand, so does the production of plastic waste. However, repurposing plastic waste is possible through the plastic pelletizing recycling system. This system converts plastic scraps into usable clean raw material in a closed-loop recycling process.
What is Plastic Pelletizing?
Plastic pelletizing is the process of converting scrap plastic into pelletized plastics. The process involves cutting plastic scraps into small pieces and heating them until they melt. The molten plastic is then passed through a die, which produces cylindrical pellets. These pellets can be reused as raw material in manufacturing plants, thereby reducing raw material costs.
Types of Pelletizers
There are different types of pelletizers, and the choice of pelletizing machine depends on the type of plastic scrap material and the quality of pellets needed. The different types of pelletizers include strand pelletizers, underwater pelletizers, and water ring pelletizers.
The strand pelletizer cuts molten plastic strands into pellets, while the underwater pelletizer submerges the plastic melt into water to cool and solidify the pellets.
The water ring pelletizer cools and solidifies the plastic melt in a ring of water before cutting it into pellets.
Difference Between Underwater Pelletizer and Water Ring Pelletizer
The main difference between the underwater pelletizer and water ring pelletizer lies in the cooling and solidification process.
The underwater pelletizer cools the molten plastic in water, which reduces the heat transfer process and allows for a better quality pellet.
The water ring pelletizer, on the other hand, uses a ring of water to cool and solidify the plastic melt.
Advantages of Pelletization
The main advantage of pelletization is the reduction of plastic waste.
Pelletization allows plastics manufacturers to realize their green initiatives by reducing waste and converting scrap plastic into high-quality materials that can be used in manufacturing processes.
Additionally, pelletization allows for easy storage, transportation, and handling of plastic pellets.
Disadvantages of Pelletization
The main disadvantage of pelletization is the cost of the pelletizing system, including the heating and cooling system, transmission system, and extrusion system.
Additionally, third-party services may be needed to attain high-quality materials. However, these costs can be offset by the savings in raw material costs and the environmental benefits of the recycling process.
Feed Size in Pelletization
The feed size in pelletization depends on the type of plastic scrap material and the type of pelletizing machine. Generally, the smaller the feed size, the better the quality of pellets produced.
Purpose of Pelletization
The purpose of pelletization is to convert plastic waste into usable clean raw material for manufacturing processes. Pelletization allows plastics manufacturers to reduce their environmental impact by reducing waste and reusing materials.
Difference Between Pelleting and Extrusion
Pelleting and extrusion are similar processes, but they differ in the form of the end product. Pelleting produces cylindrical pellets, while extrusion produces plastic film or other shapes.
Pelleting is ideal for converting scrap plastic into raw material for manufacturing processes, while extrusion is ideal for producing plastic packaging or other products.
Factors that Determine the Quality of Pellets
The quality of pellets is determined by several factors, including the type of plastic scrap material, the type of pelletizing machine, and the heating and cooling system used.
Additionally, the quality of pellets can be affected by the transmission system and the extrusion process. It is essential to work with a reputable plastic pelletizing company that values the quality of their products and the satisfaction of their customers.
Conclusion
When selecting a custom plastic pelletizing system, it is essential to consider factors such as the transmission system, extrusion process, heating and cooling system, and third-party services offered by the manufacturer.
Many plastic pelletizing companies, including Nicety, offer custom plastic pelletizing systems that can be tailored to meet the needs of plastics manufacturers.
