The following introduces the process of bronze casting and forging process, in order to let you understand the similarities and differences of these two processes in more depth.
 
Casting Process,
 
1. Designing.                                                                                                                                                 
Our designing team will design 2-3 drafts for comparison and selection according to the customer's design requirements. The design carrier needs to be selected according to the shape of the sculpture. If it is a sculpture of a character, an animal, or an irregular, complicated texture, or the shape is too small, we will make a clay model. If the shape is regular, it can be done directly using computer 3D modeling technology.
Alternatively, if the customer has a design, if it is a small draft, we will generally perform a 1: 1 scale-up process, and then combine the production process and internal structure requirements to properly optimize the model without changing the external shape of the sculpture.

2. Modeling
Clay modeling and 3D modeling are only the first step in making a model. After obtaining the clay model confirmed by the customer, the FRP model will be converted afterwards to facilitate the transportation and storage of the model. In the foundry, silicone and wax molds are produced. The 3D model will directly use 3D printing or engraving technology to produce a more accurate model quickly and directly. Then, a silicone mold and a wax mold are followed.
Putting the prepared wax mold into the soaking tank, to make it wet, and take it out and wrap it with quartz sand, then hang it to dry for next step use.

3. Casting
The wax mold coated with quartz sand will become hard after drying, putting it in the furnace and heat it, so that the wax inside will melt out from the reserved holes. Slowly pour the molten copper and bronze water from the reserved injection opening to the mold. After being left to cool, the quartz sand is knocked out, and then the sand blasting treatment is performed to obtain a copper bronze casting product.

4. Welding
For small sculptures, we can cast them all one time, which is simpler. However, for large-scale bronze sculptures, it needs to be divided into small pieces for block casting. Welding each single cast copper plate after casting to form a complete large-scale copper sculpture.

6. Grinding & Polishing
After sand blasting, the surface is still uneven or smooth, which requires grinding and polishing to make the surface of the copper bronze sculpture smooth. This process requires a special polishing master to complete the polishing process of the sculpture surface using various sizes of polishing equipment. This process plays a very important role in the later molding of the sculpture.


6. Finish
In order to make the sculpture look more beautiful, to reduce the corrosion damage to the sculpture by harmful substances such as acidic air and moisture, and to prolong the service life of the sculpture, special treatment is usually applied to the bronze outer surface. The most commonly used bronze sculpture surface treatment methods are patina, painting, gold leaf, and electroplating. We do not recommend mirror polishing, because the copper bronze material will be oxidized very quickly if it is directly exposed to the air, and the mirror effect will be destroyed in a short time. The post-maintenance cycle will be shorter and the cost will be higher.
After the surface treatment, a bronze sculpture is completed. The whole process seems simple, but it is also very difficult to grasp the key steps, such as how to cast more perfectly when pouring, without generating bubbles or how to better repair small sand holes when welding.


An exquisite bronze sculpture cannot be separated from the joint efforts of the masters in each step, which requires everyone to work together. Sino Sculpture always adheres to the corporate philosophy of quality first, so that each piece of bronze sculpture from our hands can shine in all corners of the world and bring beauty to humanity.
 
Over the past 20 years, Sino Sculpture have produced hundreds of metal sculpture projects of various sizes for artists, designers, galleries and around the world. Many excellent and very different bronze artworks are spread all over the world. Here are some excellent cases.

The copper bronze forging process is simpler in terms of procedures, because it is a cold treatment method, copper will not be melted at high temperature, so the pollution to the environment will be much smaller. It is an environmentally friendly manufacturing process. The production steps are as following,
 
1. Cutting
Forging a copper bronze sculpture, the first step is to divide the partition on the model, then use cardboard to cut according to the size of the partition, and then cut the same size copper bronze plate according to the cut cardboard. This step we called it cutting.


2. Forging
The forging master will use the custom-shaped hammer to beat the cut copper plate tens of thousands of times, so that the shape of the copper plate is completely consistent with the corresponding partition shape on the model. Then repeat the forging process continuously, so that the shape of the copper plate corresponding to each partition on the model matches.
This procedure is a key step in the forging process and it directly affects the effect of the final sculpture after molding. This step needs to be completed and checked by an experienced forging master. Each of the forging masters in Sino Sculpture company is carefully selected and has excellent forging craft and rich forging experience.


3. Welding, Grinding
Each forged copper plate is welded together in turn. The thickness of the forged copper plate is 1.5mm-4mm. Welding uses argon arc welding and full penetration welding to ensure that the copper bronze plate is not cracked and not deformed. Use a portable hand-held sander to grind and polish each weld line, and finally perform flaw detection and other tests on each weld to ensure welding quality.


4. Finish
The finish of forging craft is same as the casting’s.

Completing so many fine bronze sculptures and won praises from the world, and as a leading metal sculpture fabrication company in the industry, what specific advantages do we have? The following are the answers.
 
1. Correct company philosophy
Attaching importance to quality and craftsmanship --- Sino Sculpture Group regards quality as life. The production of each sculpture, from the selection of materials and accessories, must go through layers of checks, and the production of sculptures also needs to be checked and accepted several times. If there is a problem in any step, it is immediately ordered to modify and adjust until it is qualified. Eliminate masters with poor craftsmanship to ensure team level. It is our responsibility to serve every customer wholeheartedly, thinking of what the customer thinks, and actively feedback the customer.


2. Pay attention to investment
Keep abreast of industry trends and apply new equipment and process methods to actual production in time. Constantly learn, innovate, and reward the innovative employees. Since 2017, Beijing has been increasing its pollution control efforts. Under pressure, Sino Sculpture have relocated its factory to Xiamen, and the office also changed. However, our company actively dealt with it and quickly completed the production transfer. The new office building was also opened quickly, which will not delay the operation. The construction period needs to catch up, and various tasks are also connected in an orderly manner. All of this cannot be achieved without the decision and investment of our company's leaders.
 
3. Ultra-high process level
Sino Sculpture attaches great importance to the quality of bronze sculptures, and has also achieved very good results. This is inseparable from the specialized research and improvement of technology. When selecting enterprise personnel, they are carefully selected and included in the production team after strict assessment to ensure the consistency of the process level of the production team. We also actively learn advanced technology at home and abroad, and apply advanced production equipment, such as welding equipment, grinding and polishing equipment. Constantly break through the original process limitations to achieve higher process standards.


4. Professional Service System
From the customer's inquiry to the successful delivery of the sculpture, the designated foreign trade sales follow the entire process to ensure smooth communication. Foreign trade sales play a key bridge role in all steps. In the inquiry stage, actively communicate with each customer to understand the customer's real needs and the specific requirements of sculpture production, and provide quotations according to them. During production, we will regularly feedback the production progress to customers and report the project situation. Before the sculpture is delivered from the factory, after the self-acceptance, the final acceptance is performed with the customer to ensure that the sculpture is delivered in accordance with the contract standards. Our company has a professional transportation team that can cooperate to provide global shipping and air transportation services, ensure that clients receive the sculptures in a complete and timely manner.


5. Strong ability of Overseas Installation
From the America to Europe to Asia, our overseas installation teams travel to different countries every year to provide professional installation services for large-scale sculptures. Compared with stone-based sculptures, metal sculptures have unparalleled advantages. One is that they are lightweight and the other is that they are easy to separate and re-weld. Convenient for transportation and installation of large sculptures. Perfect overseas installation team management, and actively cooperate with local technicians to ensure the smooth implementation of the installation work and demonstrate the spirit and dedication of Sino Sculpture craftsmen. The effective implementation of the installation plan and the steady advancement of the installation work allow the sculpture to be smoothly realized in accordance with the design requirements. And we oversea installation team won unanimous praise from customers.
 


-Bronze Sculpture-

I, What is Bronze Sculpture?

As the development of the metallurgical technology, more and more kinds of metal, as material, have been used in sculpture fabrication. Bronze – is one of the oldest metal material was found and used for statues, reliefs, sculptures and artworks in ancient time.

The bronze’s strength and ductility is an advantage when figures in action are to be created, especially when compared to various ceramic or stone materials (such as marble sculpture). These qualities allow the creation of extended sculptures.

Figure 4, Donatello – David, 1428
Figure 5, Benvenuto Cellini – Perseus, 16th C,

II, What is the Material & Composition for Bronze Sculpture? 

Bronze is an alloy that is produced primarily from a mixture of copper and tin. There are 2 kinds of bronze material commonly used to cast sculptures, 
1. Silicon Bronze
(Cu-94.48%; Si-4.18%; Sn-0.04%; Pb-0.01%; Fe-0.15%; Sb-0.001%; Ni-0.01%; Al-Nil; Mn-1.12%)

Silicon bronze is a low-lead brass alloy that is generally composed of 96 percent copper. Silicon Bronze is known for its easy pouring ability, appealing surface finish and superior corrosion resistant properties, even when submerged in liquids and chemicals. Silicon Bronze was originally developed for the chemical industry but later expanded due to its good casting characteristics.


2. Tin Bronze
(Cu-87%; Sn-7.5%; Pb-0.3%; Zn-3%; Fe-0.2%; Ni-1%; Sb-0.2%; P-1.5%; S-0.05%; Al-0.005%; Mn-N/A; Si-0.005%)

Tin bronze is strong and hard and has very high ductility. This combination of properties gives them a high load-carrying capacity, good wear resistance, and the ability to withstand pounding. The alloys are noted for their corrosion resistance in seawater and brines.

Copper bronze, as a material for sculpture with a long history, has an indelible status in the world of art. Even today, bronze copper is one of the indispensable materials for making metal sculptures. Bronze casting, this ancient technique still occupies an important place in today's bronze sculptures. Our foundry still retains the casting process. In order to improve the quality of the cast products, our company uses a large number of high quality new copper bronze casting to ensure the copper purity. Constantly update production equipment to take production technology to the next level. Master casting workers have many years of copper casting experience, and the technology level is leading in the industry. At the same time, our company has continuously increased team building and learned excellent casting process skills at home and abroad. There is another emerging process of making copper bronze sculptures-bronze hand forging-which has begun to rise in the past 10 years. It is different from the traditional casting process. It is a cold treatment method. It directly uses  hammer to forge it into a model consistent shape, and then welding each piece of forged plate in turn to form a complete sculpture. It is like putting a copper or bronze plate shell on the model. This is a more advanced craft. Of course, the skills of the forging workers are higher. If the worker’s skill level is not high enough, the sculpture surface will be uneven or smooth in the future, and the aesthetic sense will be lost.
