What is the Production Process of Bronze Cast Sculpture?

The production of bronze cast sculptures involves several key steps: initial design and concept development, selection of high-quality copper materials, meticulous shaping and detailing using specialized techniques such as hammering and welding, application of surface finishes like polishing or patination to enhance aesthetics, final assembly, thorough inspection for quality assurance, and careful packaging for safe delivery to clients or exhibition venues. Each stage requires expertise and attention to detail to create stunning artworks that embody both artistic vision and technical skill.

step1. Conceptualization and Design:

Aongking begins by thoroughly understanding your artistic concept and requirements. This stage involves collaborative discussions and may include sketches or digital renderings to visualize the sculpture’s form and details.

Our team of experienced designers works closely with you to refine the design, ensuring it captures the essence and emotion you wish to convey through the sculpture.

Feedback loops are integral, allowing for adjustments and approvals to ensure the final design meets your expectations perfectly.

step 2: Material Selection and Preparation:

Choosing the right copper materials is crucial for achieving the desired aesthetic and durability. Aongking selects high-quality copper sheets or blocks based on the specific requirements of your sculpture.
Before shaping begins, the copper sheets are meticulously prepared. This includes cutting them into appropriate sizes and possibly annealing them to soften the metal for easier manipulation.

step 3: Modeling and Prototyping:

To translate the approved design into a tangible form, Aongking often creates a prototype or small-scale model. This step allows us to test proportions, details, and overall aesthetics before proceeding with full-scale production. Your feedback on the prototype is valued, and any necessary adjustments are made to ensure the final sculpture reflects your vision accurately.

After the production of the design scheme and clay sculpture (refer to the production of the model). Mold turning before casting sculpture: After the clay sculpture is finished. Before casting the bronze sculpture. We need to turn a silicone mold from the mud film. After the silicone mold was completed, the bronze sculpture was ready to be cast.

step 4: Fabrication and Shaping:

4.1 Skilled artisans utilize a variety of techniques to shape the copper sheets into the desired form. These techniques may include hammering, folding, and welding, each performed with precision and attention to detail.

4.2 Wax-type filling system: the melted paraffin wax is poured into the silicone mold that has been made. Let the paraffin cool down. Remove the molded wax mold. Then the wax mold is trimmed.

4.3 Shell making: there are two kinds of shell making and mold turning. One is precision casting (briefly). The other is made of resin sandbox. Aongking will make a choice according to the situation of the two kinds of turning schemes. Generally speaking, we choose precision casting for small sculptures or sculptures with complex details. The sandbox production is generally suitable for simple without too complex details and the surface of the sculpture is smooth.

4.4 After the candidate turns over the plan, pour the wax mold with mortar, and repeat the pouring until the mortar completely covers the wax mold to a certain thickness. Dry the wax mold wrapped in mortar. Then put the shell in the oven and heat it until the paraffin melts. This is the lost wax method of traditional casting.

4.5 Casting and polishing: The copper ingot is converted into copper water at high temperatures. Pour copper water into the finished shell or sandbox. And then clean the riser grinding.

4.6 Splicing forming: such as casting cold to go. Put the polished bronze pieces together. Through the welding process. It is to make all castings into a complete whole. Once this is done, we should be able to see the general shape and appearance of the cast copper sculpture.

step 5: Detailing and Surface Treatment:

Intricate details and textures are meticulously added to enhance the sculpture’s visual interest and depth. Artistic techniques such as chasing, engraving, or applying patinas are employed to achieve desired surface finishes and coloration. Surface finishes, whether polished to a high sheen or textured for a more organic look, are carefully applied to complement the sculpture’s design and environment.

Product casting dressing and treatment: for welded castings. The surface is extremely rough. Copper products after welding also need to be sandblasted, cleaning, grinding, shaped, machined, polishing, and other processing.

step 6: Assembly and Integration:

If the sculpture consists of multiple components, they are seamlessly integrated using advanced welding or soldering techniques. This ensures robust construction and a cohesive appearance that aligns with the original design concept. Rigorous quality checks are conducted throughout the assembly process to maintain our commitment to craftsmanship and ensure each sculpture meets our exacting standards.

Surface effect treatment and protection of casting sculpture: coloring is usually divided into cold coloring and hot coloring. According to the author’s requirements on the surface of the copper sculpture color, the cast copper surface treatment required effect, so that the shape and color achieve perfect unity.

Oiling and sealing wax: after cleaning the welding joint and coloring the surface. The next is to cast a good sculpture surface oil, and sealing wax. Oiling, and sealing wax steps can make the sculpture surface for a long time to maintain a new feeling.

step 7: Final Inspection and Finishing:

Before leaving our workshop, each sculpture undergoes a comprehensive final inspection. This includes meticulous examination of details, finishes, and overall quality to confirm it meets both our rigorous standards and your specifications.
The sculpture is carefully cleaned and prepared for transport, ensuring it arrives at its destination in pristine condition.

step 8:Delivery and Installation:

We coordinate secure transportation of the sculpture to your designated location, handling logistics to ensure safe delivery.
Upon arrival, our team provides expert guidance and support for the installation process, ensuring the sculpture is positioned and displayed to maximize its visual impact.

step 9: Documentation and Your Care:

Alongside the sculpture, we provide documentation such as certificates of authenticity and care instructions. This helps preserve the artwork’s value and longevity, offering peace of mind for your investment. Our commitment to your satisfaction extends beyond delivery. We offer ongoing support and advice to ensure your sculpture continues to captivate and inspire for generations.
