The nozzle is constructed from high-quality hot-formed steel, treated with high-temperature carbonization and hardening for superior wear and heat resistance. Boasts high hardness and toughness for a long lifespan, compatible with most high-temperature printing accessories on the market. Clearly marked letters for easy differentiation. The flat contact surface effectively resolves material leakage issues. The chamfered edge reduces resistance and cutting angle resistance, ensuring smooth cutting. The entire unit is hardened for high temperature resistance, corrosion resistance, and smoother filament extrusion.
