What is Bronze Casting？
Cast bronze has a very long history and mature technology. It has good storability for artistic creation, so it is suitable to be the material for fine works and is very popular among artists, especially figure sculpture is most common. However, oxidizing is easy, so more attention should be paid to its maintenance.
The “lost wax casting method” is also called “dewax casting bronze”. The usual lost wax casting process is summarized as follows.
Advantages of Bronze Casting
Corrosion Resistance
Bronze castings withstand moisture, seawater, and chemical environments, making them highly durable for outdoor and marine applications.
High Strength & Wear Resistance
Bronze alloys combine strength with excellent wear resistance, ideal for components subject to heavy loads and friction such as bearings, gears, and valves.
Good Machinability & Castability
Bronze flows well in casting molds, allowing the production of complex shapes with fine details, while also being easy to machine for precision requirements.
Wide Industrial Applications
With reliable mechanical and anti-friction properties, bronze castings are widely used in pumps, valves, ship parts, decorative items, and engineering machinery.
Processes of Bronze & Brass Casting
Clay Modeling
A clay prototype is first sculpted based on the design draft. The quality of this model directly influences the accuracy and aesthetic value of the final product.Silicone Mold Making
High-precision silicone molds are created from the clay model to capture fine details.Resin Prototype
Resin is poured into the silicone mold to produce a strong and accurate prototype.Resin Finishing
The resin prototype is polished and refined to achieve the desired texture and surface quality.Wax Pattern Production
A new silicone mold is made from the resin prototype. Heated paraffin wax is injected into this mold to form wax patterns that replicate the final product.Wax Pattern Trimming
Each wax pattern is carefully trimmed to remove seam lines and imperfections, ensuring consistency with the resin prototype.Ceramic Shell Formation
Wax patterns are repeatedly dipped into slurry and coated with fine sand, building a ceramic shell (5–7 layers, ~9mm thick). The wax is then melted out, leaving a hollow mold.Metal Casting
The ceramic mold is fired at 1000–1150°C, and molten bronze or brass is poured in. After cooling, the shell is broken to reveal the rough casting.Casting Cleaning & Repair
The cast product undergoes sandblasting, cutting, grinding, shaping, heat treatment (if applicable), and machining to achieve dimensional accuracy.Surface Treatment & Protection
Final finishing includes polishing, coloring (cold or hot patina), and protective waxing to enhance durability and appearance.
