China Copper Sculpture Industry Network News China Copper Sculpture Industry Network recommends Xi'an sculpture design to introduce you to the standard production process of garden bronze sculpture
The sculpture sculptures such as garden bronze sculptures are firstly shaped by clay sculptures, then the negative molds are turned over, and the negative molds are turned over and then turned into male molds. This is actually a process of material conversion, that is, conversion from plastic clay products to Shijiazhuang foam sculptures. It is shaped with different materials such as FRP and finally sent to a professional foundry for the final casting process. Each piece of garden bronze sculptures needs to be produced through at least 8 complicated and rigorous processes. These processes include traces of traditional handicrafts and modern techniques of precision casting. You can learn about the standard craftsmanship of garden bronze sculptures. Process.
The first step: making small clay sculptures (the predecessor of each product needs a clay sculpture prototype. The clay sculptures are re-created after the sculptor repeatedly tries to figure out and refine the original design draft. The clay sculpture is good and bad, and the charm is The expression of intention or intention directly affects the quality of future products, so excellent clay sculpture can not be separated from excellent sculptors)
The second step: the large mud covers the sculpture shape. After the mud is finished, the raft is used to fill the mud. After all the mud, the large shape is constantly adjusted. The shape is not allowed to rework to rest the skeleton until it is satisfied. The above must be done by a professional sculptor. From this stage, the sculpture must always be sprayed with water to keep it from cracking. The halfway will be covered with plastic film to moisturize until the sculpture mold is completed.
The third step: making the mud sculpture prototype (the re-made silicone mold has been completely intact and intact, and the heated and melted paraffin is pressurized and injected into the silicone mold to produce a wax embryo, which will produce the product. A true replica of the shape.)

The fourth step: the sculpture is completed in large scale, and Party A is notified to review and make comments or revisions to the large model. Continue to continually refine the adjustments and details to achieve perfection. After all the styling is completed, the overall push-up clay is used, and the scraper is used to push the light. The prototype of the mud sculpture needs to be trimmed against the prototype body of the third process. This is an important part. Therefore, the link will directly affect the final shape and surface effect of the product.
Step 5: Enter the re-stage, use the slice on the clay to divide the block mold design, and then spray soapy water as isolation protection. The professional turning technician mixes the gypsum slurry on the sculpture, and the specific water content of the inner layer of the specific gypsum slurry is mastered and completed by the professional. After the gypsum is hardened and dried, the mold release is started. Before the mold release, the gripper is fixed on the block, and the gripper is made of gypsum numb pile.
Step 6: Remove the residual mud on the block mold after demoulding. After the completion, carefully repair the plaster mold and make up the grinding. It is then ground with a metal copper mesh.
Step 7: Casting (the hollow ceramic shell of the previous process is placed in a sintering furnace and sintered at 1000 °C to 1150 °C according to different alloy materials. The copper liquid is immediately cast into the ceramic shell, and after cooling, the outer ceramic shell is broken and peeled off. The copper product is a rough embryo.)
Step 8: Finishing and processing of product castings (sanding and cleaning the cast copper products, and cutting, grinding, heat treatment, shaping, machining, polishing, etc.)
Step 9: Surface effect treatment and protection (the effect required on the surface of cast copper, usually with cold color and hot color, and finally wax protection and polishing)
