In the plastics extrusion industry, efficiency, precision, and product quality are key factors in determining success. One of the most advanced solutions in modern extrusion lines is the twin-screw air-cooled die-face hot-cutting unit. This cutting-edge technology enhances pelletizing performance, reduces material waste, and improves overall production efficiency.
For companies looking to optimize their extrusion and recycling processes, JiaXin Mechanical Manufacture offers high-performance twin-screw extruders and customized turnkey solutions. With expertise in compounding, recycling, and sheet production lines, JiaXin provides innovative, energy-efficient, and cost-effective solutions for the plastic industry.
What is a Twin-Screw Air-Cooled Die-Face Hot-Cutting Unit?
A twin-screw air-cooled die-face hot-cutting unit is a pelletizing system used in plastic extrusion lines. It involves cutting molten plastic into uniform pellets immediately as they exit the die. Instead of using water to cool the pellets, air cooling is employed, which is ideal for moisture-sensitive materials and high-temperature processing.
Key Components:
✅ Twin-Screw Extruder – Ensures homogeneous mixing and stable extrusion of plastic materials.
✅ Die-Face Cutter – Cuts molten plastic into precise, uniform pellets at the die face.
✅ Air-Cooling System – Rapidly cools pellets without water, preventing contamination or excess moisture.
Benefits of Twin-Screw Air-Cooled Die-Face Hot-Cutting Units
1. High Production Efficiency
Compared to traditional water-cooled systems, air-cooled die-face cutting offers faster pelletizing and drying processes, leading to higher output rates.
2. Moisture-Free and Contaminant-Free Pellets
Since water is not used in the cooling process, pellets remain dry and free from contamination, making this system perfect for materials that are hygroscopic or sensitive to moisture, such as PET, TPU, and PA.
3. Energy and Cost Savings
Air-cooled systems eliminate the need for water circulation, filtration, and drying, reducing energy consumption and maintenance costs. This leads to lower operational expenses and a more sustainable production process.
4. Improved Pellet Quality
With precise cutting and efficient cooling, pellets have a consistent shape, smooth surface, and minimal fines, ensuring better downstream processing and final product quality.
5. Versatile Material Processing
A twin-screw extrusion system combined with air-cooled die-face cutting allows for the processing of a wide range of materials, including:
