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.

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.
