Product advantages:

1. Stainless steel throat: Stainless steel laryngeal tube built -in iron fluorine, suitable for low temperature printing (within 260 ° C)

2. Titanium alloy throat: Titanium alloy reduces heating blocks upward heat, high hardness, wear resistance, suitable for high temperature printing (within 300 ° C)

3. Copper+titanium alloy throat: Due to the use of dual metals, titanium alloy reduces heating blocks up upward heat transmission, copper's heat dissipation is better, and the overall heat partition effect is better (within 300 ° C)

4. Copper -plated nozzle is more durable
