**Product Specifications:**
- **Model No.:** 150mm x 200mm x 3900mm
- **Origin:** Zhejiang, China
- **HS Code:** 84779000
**Application:**
The extruder screw barrel is designed for the transportation, compaction, melting, mixing, and pressurization of plastic materials. These processes are achieved through the rotation of the screw inside the barrel, ensuring efficient and consistent performance in industrial applications.
**Material:**
Manufactured using high-quality 38 Chromium Molybdenum Lithium material, the screw barrel undergoes nitriding treatment to enhance its durability and resistance to wear. This ensures long-lasting performance and reliable quality.
**Maintenance Tips for Screw Barrel:**
1. Do not start the machine until the barrel reaches the preset temperature. New electric heating systems typically require 30 minutes after the screw starts operating before it's ready for use.
2. After each downtime lasting more than half an hour, it’s recommended to close the material inlet, clean the barrel, and set it to insulation mode.
3. Prevent foreign objects from entering the barrel, as they can damage both the screw and the barrel. If processing recycled materials, a magnetic hopper should be used to avoid metal debris from entering.
4. Use anti-slip measures to ensure the plastic melt is fully formed, preventing damage to the transmission system and screw back.
5. Avoid idle or slipping conditions of the screw to maintain smooth operation.
6. When using new plastics such as POM, PVC, or PA+GF, make sure to thoroughly clean the barrel after use to minimize material degradation. Rinse promptly after shutdown.
7. Never mix POM and PVC together in the barrel, as this could lead to dangerous chemical reactions at high temperatures.
