The casting and processing customization of
bronze castings mainly involve the following aspects:
1. Casting process
Sand casting
This is one of the most commonly used casting processes, suitable for larger and complex bronze castings, with low cost but high surface roughness.
Precision casting (lost wax casting)
Precision molding through wax molds, suitable for small or complex parts that require high precision and delicate surface treatment.
Centrifugal casting
Suitable for the production of hollow, annular bronze parts, such as bronze tubes or bronze rings.
Pressure casting
Small and complex parts used for mass production, with fast production speed and high precision.
Continuous casting
Suitable for the production of large quantities of long bronze materials, such as bronze rods and bronze strips.
2. Processing technology
Machining
Further processing such as turning, milling, drilling, etc. is carried out after casting to obtain the required size and tolerance.
Surface treatment
Includes grinding, polishing and electroplating to improve surface finish and corrosion resistance.
3. Customization process
Design and drawing confirmation
Based on the design drawings or requirements provided by the customer, the manufacturer will conduct 3D modeling and scheme confirmation.
Mold making
The casting mold is made according to the design drawings, and the mold cost will vary according to the complexity.
Sample making and confirmation
The sample is cast according to the mold and sent to the customer for confirmation.
Mass production
After the sample is confirmed, mass production is carried out.
4. Price factors
The price of bronze castings is affected by many factors, including:
bronze material price
bronze is a more expensive metal, and market price fluctuations will directly affect the cost of castings.
Casting process
The cost of different processes varies greatly, and processes such as precision casting and pressure casting are more expensive than sand casting.
Part complexity
The more complex the shape, the more processing technology and time are required, and the cost increases accordingly.
Batch size
Mass production can usually reduce the cost per piece.
Surface treatment
Special treatments such as polishing or electroplating will increase the cost.
5. Approximate price range
The price range of bronze castings is wide, usually ranging from tens of yuan to thousands of yuan per kilogram, depending on the process, material and customization requirements. For example:
Simple sand castings may cost 50-100 yuan per kilogram.
Complex precision casting parts or bronze parts with special surface treatment may cost 300-1000 yuan per kilogram, or even higher.
If you have specific customization needs, it is recommended to contact the foundry directly, provide design drawings or detailed requirements, and obtain a more accurate quotation.
