Custom Copper Alloy Casting Parts
Copper Alloy Casting Process
Sand Casting
Sand casting uses sand as the mold material, then pours the molten copper solution into the mold, removes the casting after cooling, and cleans and post-processes it.
· The mold manufacturing cost is low and can be used many times
· Casts large and medium-sized castings with complex shapes and large sizes.
· Suitable for small, medium and large batch production.
Die Casting
Die casting is the process of injecting molten metal into a metal mold cavity under high pressure to quickly fill the cavity and solidify it. It is suitable for mass production of thin-walled, complex, and high-precision parts.
· The casting surface is smooth and the dimensional accuracy is high.
· The production cycle is short and suitable for mass production.
· The metal loss is small and the cooling in the mold is fast.
Gravity Casting
Gravity casting usually uses metal molds or sand molds, and the metal solidifies and forms under natural conditions. It is suitable for parts of medium complexity.
· The mold cost is low and suitable for small and medium batch production.
· Larger parts can be produced with better density.
· The price of parts is low.
Investment Casting
Investment casting uses soluble or combustible casting molds (such as wax molds) to make castings, and is often used to make copper parts with complex shapes and high precision requirements.
· High surface quality
· No need for a lot of post-processing
· Suitable for small batches and high precision copper parts
Machining
Machining is a post-processing process for copper castings, which improves the accuracy, surface quality and functionality of castings through fine processing.
· Optimize appearance quality
· Improve part structure and function
· Process thin walls and complex shapes
Surface Treatment
Surface treatment can transform the surface of copper castings by physical, chemical or mechanical means to improve the surface quality of castings, increase their durability, and improve appearance and functionality.
· Improve surface hardness
· Improve appearance and improve dimensional accuracy
· Improve adhesion and corrosion resistance

Copper Alloy Castings Custom Steps
Confirm customization requirements
1. Provide detailed design documents or samples of parts
The engineering team will review the 3D drawings (CAD models) and corresponding processing plans provided by customers to ensure that they meet manufacturing requirements.
Samples: If customers provide samples, we can also produce according to samples.
2. Confirm the material of the casting
Choose the appropriate cast copper material according to the use environment, technical requirements or customer requirements of the parts. We will give reasonable suggestions based on the price, mechanical properties, wear resistance, corrosion resistance, etc. of the materials.
3. Confirm the casting process
Determine the appropriate casting process based on customer needs and part price, shape, size, precision, material, etc.
4. Confirm the requirements for various product attributes
Confirm the various performance requirements of the parts under the casting process and materials, such as strength, hardness, wear resistance, corrosion resistance, etc.
According to the drawings and product requirements, confirm the dimensional tolerance and precision requirements, surface roughness, appearance quality and other requirements of the product.
5. Make molds and samples
Make casting molds that meet the requirements according to the drawings or samples provided by the customer; and cast the selected casting materials through the corresponding process to produce the first batch of samples
