The purity of aluminum liquid is the decisive factor affecting the internal quality of wheel hub castings, and it needs to be perfectly matched with mold structure and process parameters to achieve high-quality molding. Even high-precision molds will produce a large number of defective products if matched with impure aluminum liquid containing oxides, gas and floating slag. Zhejiang Xinfeng Machinery summarizes professional mold adaptation schemes for purified aluminum liquid, forming a complete high-quality casting system.
Multi-stage aluminum liquid purification technology provides high-purity raw materials for molding. Through professional filtering, degassing and slag removal processes, the impurity content of molten aluminum is reduced by 75%, removing most oxide floating slag and internal dissolved gas. The high-purity aluminum liquid fundamentally reduces the source of casting defects, laying a foundation for zero-defect molding of precision molds.
The optimized mold venting and gating system perfectly adapts to purified aluminum liquid characteristics. The hierarchical high-efficiency venting structure cooperates with low-gas purified liquid, reducing casting internal gas residue by 82%. The low-turbulence gradient gating speed avoids secondary oxidation of purified aluminum liquid during filling, reducing oxide inclusion defect rate by 78% and ensuring the internal purity and surface finish of wheel hubs.
Constant-temperature liquid supply and parameter matching stabilize long-term quality. The aluminum liquid temperature is stably controlled within ±4℃ fluctuation range, cooperating with the mold zoned cooling system to realize balanced solidification. The pure and uniform internal structure eliminates defect stress concentration points, improving the overall fatigue resistance of wheel hubs by 21%, making the products more adaptable to long-term high-load driving conditions.
