Quale materiale offre le migliori prestazioni negli ugelli a canale caldo?

I. Vantaggi della resistenza alla corrosione del nucleo Progettazione della composizione mirata: circa 57% di nichel, 16% di molibdeno e 3-4% di tungsteno, con conseguente resistenza significativamente superiore ai prodotti di decomposizione contenenti fluoro come l'HF rispetto ad altre leghe convenzionali. Resistenza alla corrosione ad alta temperatura: alla normale temperatura operativa del canale caldo di 300 gradi, il tasso di corrosione è<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.
