Copper castings, as a common metal component, are prone to fracture and deformation during the manufacturing process. To avoid these issues, the following are some feasible measures recommended by Dalian copper casting manufacturers:

1. Reasonably design the structure of copper castings

In the design process, the mechanical characteristics of the parts should be taken into consideration and stress concentration areas should be avoided as much as possible. Stress concentration can be reduced by adding reinforcement bars, chamfering, transitional bending, and other measures.

2. Use appropriate materials

Choose appropriate copper alloy materials to meet the requirements of the parts. Different copper alloys have different strength and hardness characteristics, and should be selected according to specific application scenarios. In addition, it is necessary to choose the purity of the material and control the impurity content of the copper casting material.

3. Control the cooling rate of copper castings

Reasonably control the cooling rate of copper castings to avoid problems such as cold cracking and shrinkage caused by rapid cooling. Appropriate cooling media and cooling time can be used to prevent problems during the cooling process.

4. Optimize casting process

During the casting process, the casting temperature and pressure should be reasonably selected according to the specific situation to avoid problems caused by high or low temperatures. In addition, attention should be paid to the design of the mold and pouring system to avoid excessive pouring pressure and speed, in order to reduce the risk of material deformation and shrinkage.

5. Conduct heat treatment

For some castings that require high strength and wear resistance, heat treatment processes can be carried out, including quenching, tempering, solid solution treatment, etc., to improve the material's performance and fracture resistance.

6. Strengthen quality control

During the casting process, it is necessary to strictly control each process, ensure that each step is operated in a standardized manner, and avoid material defects caused by negligence. Non destructive testing techniques such as X-ray and ultrasonic testing can be used to comprehensively detect defects in copper castings.

7. Choose appropriate process equipment and tools

During the casting process, appropriate process equipment and tools should be selected to ensure the accuracy and stability of the operation. Including the selection of casting equipment, manufacturing and maintenance of molds, etc.

8. Strengthen worker training

The manufacturing process of copper castings requires highly skilled workers to operate. Therefore, it is necessary to strengthen technical training, improve the technical level and operational ability of workers, and reduce the possibility of operational errors and problems.

Avoiding the fracture and deformation of copper casting materials requires comprehensive consideration from multiple aspects such as design, material selection, and process control. Only by ensuring quality control and operational standards at every stage can copper castings have good performance and reliability.
