The plastic extruder machine, or plastic pelletizing machine, is a kind of equipment specially designed for recycling waste plastics and processing them into plastic granules, which is widely used in the plastic recycling and regeneration industry.
Through reasonable design and reliable operation performance, this equipment can process all kinds of waste plastics into uniform granules for manufacturing new plastic products. We offer a wide range of models and configurations of plastic granulators, which can meet the needs of different customers.
Advantages of Plastic Extruder Machine
- Flexible Production Capacity: The machine offers a production range of 100kg/h to 500kg/h, accommodating various production scales.
- Diverse Options: A wide range of pelletizer models is available, tailored to the raw material characteristics and production requirements of customers.
- Customizable: Configurations can be adjusted based on specific customer needs to meet unique production demands.
- Well-Designed Structure: The equipment is user-friendly, operates smoothly, and produces high-quality pellets.
- Flexible application: can be used alone or with a crusher machine, washing machine, etc. to form a complete granulation line.
Applicable Raw Materials:
Plastic extruder machines are suitable for a wide range of post-consumer and post-industrial raw materials:
- Post-consumer plastics: Such as plastic bags, PE film, food packaging materials, shrink wrap, LLDPE stretch film, bubble wrap, laminated film, jumbo bags, BOPP film, drip irrigation tape, food containers, Injection molded products, plastic barrels, battery casing, plastic baskets, flakes, etc.
- Post-industrial plastics: e.g. plastic pipes, edges and corners, injection molding waste, etc.
Benefits of Finished Plastic Pellets
The processed plastic granules have the following characteristics:
- Uniform particle size, stable quality;
- Fewer impurities, easy to reprocess.
These pellets can be used in a wide range of applications for the production of new plastic products, including injection molded parts, films, tubes, and so on.
Working Principle of Plastic Pellet Making Machine
The plastic extruder machine completes the process by the following steps:
- The raw material enters the feed inlet and is pushed to the heating zone by the screw.
- Under the action of the heating device, the plastic is melted.
- The melted plastic is extruded through the die head, forming pellets or strip-shaped materials.
- Depending on the pelletizing method, the final product is shaped into pellets through a water ring or strand cutting.
Water Ring Pelletizer System
Water ring pelletizing is a form of plastic pellet cutting that is suitable for handling molten plastics with high flowability. After the molten plastic is extruded through the die head, it is cut into pellets using a high-speed rotating pelletizing knife, and the granules are cooled by a circular water stream to prevent sticking. The cooled pellets follow the flow of water into a dewatering plant where the water is separated to give dry plastic pellets suitable for further processing or use.
Plastic Granules Machine Structure
The main structure of our plastic extruder machine includes:
- Feeding System: Introduces plastic materials into the machine.
- Screw and Heating Zone: Facilitates plastic melting.
- Die Head: Responsible for extrusion and shaping.
- Pellet Cutting System: Completes pellet cutting.
- Control Panel: Enables easy operation and monitoring of the production process.
3 Types of Heating for Waste Plastic Extruder
There are three main heating methods for plastic extruder machines in the market: electromagnetic heating, ceramic heating device, and iron heating device.
This method generates heat through electromagnetic induction, which can quickly raise the temperature and is suitable for high-efficiency production.
The ironing heater is heated by thermocouples and is suitable for production that requires high-temperature accuracy.
The ceramic heating method has stability and uniformity, suitable for the production process that needs to maintain a certain temperature.
3 types of Die Heads for Plastic Pelletizer
Plastic extruder machine is equipped with three different types of die heads to meet different pelleting needs, i.e., electric gear die head, automatic slag filter and hydraulic die head. Customers can choose the right diehead according to their needs.
Electric gear die head
The electric gear die head of the plastic recycling granulator is suitable for pellet production that requires high precision and consistency. It is driven by motorized gears to precisely control the size and shape of the pellets.
Hydraulic die head
The hydraulic die head is driven by a hydraulic system and is suitable for pellet production requiring high pressure and density.
Screenless slagging die head
The screenless slagging die head automatically filters out unwanted material to ensure the purity of the finished product.
