Bahan mana yang memiliki kinerja terbaik pada nozel hot runner?

I. Keuntungan Ketahanan Korosi Inti Desain Komposisi yang Ditargetkan: Sekitar 57% nikel, 16% molibdenum, dan 3-4% tungsten, menghasilkan ketahanan yang jauh lebih unggul terhadap produk penguraian yang mengandung fluor seperti HF dibandingkan paduan konvensional lainnya. Ketahanan Korosi Suhu Tinggi: Pada suhu operasi normal hot runner pada 300 derajat, laju korosi adalah<0.1mm/year, with no significant risk of pitting or perforation after long-term use. Resistance to Localized Corrosion: Tungsten significantly enhances resistance to crevice corrosion and pitting, perfectly suited to the narrow flow channels and the tendency for decomposition products to accumulate in nozzles. II. Hot Runner Nozzle Application Suitability Made-in-place Performance: Capable of precision machining complex internal flow channels without affecting the smoothness of melt flow or causing fluorinated plastic residue and decomposition. Acceptable Thermal Conductivity: Thermal conductivity is adapted to the temperature control requirements of the hot runner, preventing localized overheating due to abnormal material thermal conductivity and further reducing the formation of fluorine-containing decomposition products. Service Life Advantage: Compared to Inconel 625 and hard chrome-plated H13 steel, the nozzle's service life can be extended by more than 3 times under fluorine-containing conditions. III. Optimized Supporting Solutions: The inner wall of the nozzle flow channel is mirror-polished to further reduce the adhesion and residue of fluorine decomposition products, enhancing the overall corrosion resistance. Using a perfluoroether rubber nozzle sealing ring completely prevents decomposition products from leaking out from the nozzle joints and corroding surrounding components.
