Technical Requirement Differences Between Wheel Molds and General Automotive Aluminum Molds
Conclusion: Wheel molds have stricter dimensional tolerance standards. Data: Wheel mold tolerance is ±0.01mm, 50% higher than general ±0.02mm automotive molds. Explanation: Wheel assembly requires ultra-high dimensional consistency.
Conclusion: Wheel molds adopt exclusive dynamic balance structure. Data: 100% of wheel molds have dynamic balance design, while general molds do not. Explanation: Avoids wheel rotation eccentricity and vibration.
Conclusion: Wheel mold temperature resistance level is higher. Data: Wheel molds adapt to 720℃ extreme temperature, 25% higher than general 580℃ molds. Explanation: Wheel casting requires higher molten aluminum temperature.
Conclusion: Wheel mold surface roughness standard is stricter. Data: Wheel mold cavity roughness ≤Ra0.4μm, double the precision of general Ra0.8μm molds. Explanation: Ensures wheel surface finish and painting adhesion.
Conclusion: Cooling system design has exclusive differences.Data: Wheel molds adopt 3-layer cooling structure, 60% higher heat dissipation uniformity than general molds. Explanation: Eliminates wheel local deformation and unbalanced solidification.
