An auto parts manufacturer needs to produce nylon (PA6) fuel pipes with high temperature resistance and high dimensional stability, requiring the wall thickness error of the extruded finished product to be ≤0.1mm and the long-term temperature resistance to be ≥130℃. With the trend of lightweight automobiles, the demand for the application of PA6 materials in fuel systems has increased sharply, but traditional extruders have problems such as large temperature fluctuations and uneven plasticization.
Solution:
Use our TSE-95B twin-screw extruder, configured with:
1. Intelligent zoned temperature control system
8-stage independent temperature control module, real-time adjustment of the temperature of each section of the screw (±1℃ accuracy), solve the problem of thermal degradation during high-temperature processing of PA6, and improve the stability of the material melt flow index (MFI) by 30%.
2. Dual-channel barrier screw
Specially designed mixing section and exhaust section improve the dispersion of PA6 and glass fiber reinforcement (when the glass fiber content is 30%, the dispersion uniformity is >95%), and the finished product tensile strength reaches 180MPa.
3. Energy consumption optimization module
Integrated servo drive system, energy saving 22% compared with traditional extruders, electricity cost reduced by 15 yuan/hour during continuous production.
Project results:
Successful mass production of PA6 fuel pipe, wall thickness error controlled within ±0.08mm, temperature resistance up to 135℃ (ASTM D638 standard);
Customer production line efficiency increased by 40%, annual production capacity exceeded 2 million meters;
The case was certified as a Tier 1 supplier in the automotive industry and has been mass-produced with new energy vehicles.
