Product Advantages
High Alloy Purity
The melting process is precisely controlled in an electric arc furnace or crucible furnace at 1100°C to 1200°C, and flux is added to remove oxidized impurities. This ensures compositional uniformity and purity, improving the consistency and traceability of the casting's overall performance.
Suitable for a variety of casting processes
Sand or investment casting processes are selected based on part complexity. Sand molds are suitable for large parts, while investment casting is suitable for high-precision, detailed structures. This improves the casting accuracy and surface integrity of complex parts, reducing subsequent processing difficulties.
Strong Casting Stability
Controlled pouring temperature and speed reduce turbulence and gas entrainment, preventing metal from underfilling the mold cavity or causing porosity, improving casting density and overall mechanical stability, and reducing scrap rates.
High Dimensional Processing Precision
After cooling, the castings are machined, polished, and heat-treated using CNC equipment to ensure dimensional accuracy and geometric tolerances. Suitable for industrial assembly applications with stringent geometric requirements.

FAQ
Q: What applications are bronze castings suitable for?
A: They are primarily used for mechanical components requiring high wear resistance, high strength, and corrosion resistance, such as bearings, gears, pump bodies, and marine components.
Q: Are small-batch custom production possible?
A: Yes, we use sand or investment casting based on drawings or samples. This is suitable for small-batch customizations with complex structures or special dimensions.
Q: How is the dimensional accuracy of the castings controlled?
A: Preset mold compensation factors and CMM precision testing ensure that key dimensional tolerances are controlled within ±0.05mm to ±0.1mm.
Q: Are the castings heat-treated to enhance performance?
A: Annealing or aging treatments are available, depending on the application requirements, to improve the material's mechanical properties and dimensional stability.
Q: What surface treatment options are available for the castings?
A: Sandblasting, polishing, electroplating, or anti-corrosion coatings can be applied to enhance oxidation resistance and surface durability, depending on the application environment.
