Manufacturing process and quality control of bronze bushings

The manufacturing process and quality control of bronze bushings are the key to ensure their performance and service life. The following are some key points about the manufacturing process and quality control of bronze bushings:

Manufacturing process

Material selection:

Select suitable bronze alloy materials, commonly used are bronze, brass, etc., which have good mechanical properties and wear resistance.

Casting:

The initial shape of the bronze bushings is usually obtained through a casting process, including sand casting and investment casting. The casting process needs to control temperature and fluidity to avoid casting defects.

Forging:

In some applications, the bronze bushings may undergo a forging process to improve the strength and plasticity of the material. The forging process can make the internal structure of bronze tighter and improve wear resistance.

Machining:

Use CNC machine tools or traditional machine tools to fine-process the bronze bushings, including turning, milling, drilling, etc., to achieve the required dimensional tolerance and surface roughness.

Surface treatment:

Depending on the use, the bronze bushings may require surface treatment, such as nickel plating, chrome plating or spraying, to improve its corrosion resistance and wear resistance.

Quality Control

Material Inspection:

Chemical composition analysis and physical property test of raw materials are carried out to ensure that the bronze alloy used meets the design standards.

Process Control:

During the casting and processing process, process parameters such as temperature, pressure, cutting speed, etc. are regularly checked to ensure process stability.

Dimension Inspection:

Use measuring tools and instruments to inspect the dimensions and form and position tolerances of the bronze bushings to ensure that the design requirements are met.

Performance Test:

Mechanical property tests such as tensile test, hardness test and fatigue test are carried out to verify the actual performance of the bronze bushings.

Appearance Inspection:

Check whether there are defects on the surface of the bronze bushings, such as pores, cracks, scratches, etc., to ensure the appearance quality.

Use Data Tracking:

Record the performance of the bronze bushings in actual use, and analyze the data regularly to continuously improve the production process and quality control standards.

Through the above manufacturing process and quality control measures, the high quality and long life of the bronze bushings can be ensured to meet the needs of various industrial applications.
