Bucket Teeth Material

At Aulone, our bucket teeth are manufactured from high-quality low-alloy steel, carefully designed to provide superior strength and wear resistance for demanding construction and excavation applications. The main chemical elements include C, Si, Mn, Cr, Al, and others. To further enhance wear resistance and extend service life, we recommend adding trace microelements such as Mo and Ni.

Here is the detailed chemical composition and mechanical properties of our  AAETT® cast bucket teeth:

Aulone’s Investment Casting Process for Bucket Teeth

At Aulone, we specialize in precision investment casting for our  AAETT® bucket teeth, ensuring exceptional durability, dimensional accuracy, and performance. Investment casting allows us to produce complex shapes with tight tolerances, making it ideal for high-stress applications in excavation and construction. Below is a detailed overview of our process:

Step 1: Wax Pattern Making

The first step is creating wax patterns, which are precise replicas of the bucket teeth. High-quality wax patterns are essential, as they determine the final accuracy of the cast teeth. At Aulone, we carefully inspect each wax pattern to ensure defect-free production.

Step 2: Assembly into Tree

Wax patterns are then attached to a central wax rod, forming a structure called a “tree.” This allows multiple bucket teeth to be cast simultaneously, significantly improving production efficiency while maintaining uniform quality.

Step 3: Ceramic Shell Building

The wax tree is repeatedly dipped into a ceramic slurry and coated with fine sand to form a robust ceramic shell. Each layer is carefully dried and hardened, ensuring the mold can withstand the high temperatures of molten metal pouring. The result is a strong, heat-resistant mold that preserves the shape and surface detail of the bucket teeth.

Step 4: Wax Removal

After the shell is built, the wax patterns are removed through dewaxing in an autoclave. The wax melts and drains out, leaving a hollow ceramic mold in the exact shape of the bucket teeth.

Step 5: Metal Pouring & Shell Removal

High-quality alloy steel is melted and poured into the hollow ceramic molds. The metal rapidly cools and solidifies, forming durable bucket teeth with excellent wear resistance. After casting, the ceramic shell is carefully broken away, revealing the newly formed  AAETT® bucket teeth.

Step 6: Heat Treatment & Surface Finishing

Finally, the bucket teeth undergo heat treatment to achieve optimal hardness and mechanical properties. Surface finishing ensures smooth edges, precise dimensions, and readiness for installation. Aulone’s strict quality control guarantees that every piece meets the highest standards of performance and reliability.

This refined version emphasizes Aulone’s professionalism, the  AAETT® brand, and the high-quality, wear-resistant properties of the bucket teeth, while keeping the process explanation clear and customer-friendly.
