As the development of industry technology, the production of processing of plastic materials play an important role in satisfying the needs of today’s people.
That is why plastic extruder machine is more and more common in our daily life . The plastic extruder machine is also known as plastic extrusion machine ,it is the most important technology in the plastic industry. This plastic extruder machine continuously produces plastic materials in the form of granules , wires, strips, sheet and tubes of the desired size. This processing technology is widely used in many industries, including construction, automotive, packaging, medical equipment manufacturing, and home appliance manufacturing.
Here ,let us explore plastic granule and how do the extruder machine make these plastic granules .
This plastic granule machine is one machine that utilize heat, pressure, and mechanical shear to melt and shape plastic materials. When the raw plastic material are fed into the hopper of this screw machine ,it transform the raw materials into high-quality granules or pellets .
The plastic extruder integrate the function of plasticization and pelletizing and ideal for crushed regrinds or flakes of PE/PP/ABS/PS/HIPS/PC etc.
Basically , a plastic screw extruder mainly consists of several key parts:
* Hopper: Where raw plastic material is loaded.
* Barrel and Screw: It is the key parts of the screw extruder machine —where melting, mixing, and pushing happen in this part.
* Heaters: Surround the barrel to melt the plastic.
* Die head: Shapes the molten plastic into strands.
* Cooling system: Usually water troughs or baths to cool the plastic strands.
* Pelletizer: A cutting device that chops cooled plastic strands into granules.
So How Granules or Pellet Made ?
1. Feeding
Firstly ,the raw plastic material are fed from the hopper and then pushed into the barrel. According to special processing purpose ,some additives such as color masterbatches, stabilizers, or fillers can be added and mixed in at this stage.
2. Melting and Mixing
As the screw rotates inside the heated barrel, it pushes the raw plastic material forward. Gradually, the raw plastic material softens and melts in this area.
3. Extrusion
Then the molten plastic is pushed through a die head, which form to continuous spaghetti-like strands. The diameter of die can be adjusted as per specific needs .
4. Cooling
The hot plastic strands come out of the die and then go into a water bath or spray cooling system, which rapidly reduces the temperature and solidifies the strands.
5. Pelletizing
Once cooled and hardened, the strands pass through a pelletizer equipment, which cuts them into small, uniform granules as desired .
6. Drying and Packaging
Finally, the plastic granules are dried and collected for packaging. These plastic granules can now be used in other usage ,such as injection molding, film blowing, extrusion molding, and other plastic processing applications.
So What Benefit Can Granule Screw Extruder Can Bring for You?
1. High efficiency: Continuous operation and automation increase productivity.
2. Consistency: The screw design ensures uniform melting and mixing.
3. Flexibility: The plastic screw extruder can process a wide range of plastics, including PE, PC, PP, PS, ABS, PVC and other plastic materials.
So in conclusion ,the plastic screw extruder is very essential equipment in modern plastics processing. It simplifies the complex task of turning waste or virgin plastic into granules or pellets that can be easily transported, stored, and reused.
Whether you are in recycling, compounding, or new material production, this plastic screw machine would help you great in today’s plastic manufacturing.
