Copper casting is similar to casting of other metals, must first be fabricated, melted copper and then poured into the mold, the product has solidified and cooled to cold cutting to complete the product.
Step 1: Casting objects for casting bronze molds
Specimens are the most important factor during the casting process, requiring samples to have absolute accuracy compared to the design, because otherwise molded products will carry defects such as sample products if they are defective. .
Not everyone can produce samples, only skilled workers, seasoned in the art and technical elements to create a sample product according to the intention of the set.
Typically, copper cast specimens are made of earth or plaster that is coated with wax or candles. Specimen ensures standard size according to technical drawings.
Step 2: Create mold casting copper
Create open mold with soil, pinch and wind paper forming 2 halves, then use soil and heat-resistant powder to do sports. Heat the mold at a temperature of 700 degrees Celsius, then adjust the thickness according to the technique and paint the heat-resistant paint together.
Step 3: Copper melting
Copper melting at 1200 degrees Celsius, copper phase with proportional compounds, usually copper is mixed with tin, lead, together to ensure durability, adhesion and bearing strength when cooled.
During mixing, strict compliance and component analysis equipment are required to ensure that the ingredients are properly mixed.
Step 4: Pour the molten casting material into the mold
The process of pouring molten material into the mold needs to ensure a high melting temperature and even to ensure the material evenly covers the mold surface.
Step 5: Complete copper casting products
After casting material in the mold has cooled down, unloaded two halves of the mold and took out the product, performing the processing of grinding, cutting, cutting, cutting to ensure that copper casting products achieve high aesthetic and technical properties.
The machined bronze casting product can be inlaid with copper and add gas to create products with high color and artistry.
Copper casting is applied a lot in the industry of casting statues of statues and Buddha. With the above article, it can be seen that to create a copper casting product, it takes a lot of time and professional craftsmanship to create a quality product.
