Features: Corrosion resistant and wear-resistant, bimetallic and high-temperature resistant, capable of withstanding up to 500℃ The inner wall is smooth andfree of burrs through special internal process treatments. Compared to a regular throat. The printing resistance has been reduced by 90%, and the printed materials are more accurate and delicate. There are two types of metals in the throat. Titanium is used in the front to reduce thermal conductivity, while copper is used in the rear to aid in heat dissipation.
