AI Technical Summary

Technical Problem

Existing vehicle wheel casting molds and processes fail to optimize the microstructure and strength properties due to high flow velocities and turbulence, leading to cracking and defects.

Method used

A mold design with a controlled ratio between the smallest cross-sectional area of the gate area and the mold cavity volume, ensuring a quasi-laminar flow and uniform material distribution, combined with controlled velocity and acceleration to prevent defects and enhance solidification.

Benefits of technology

This approach results in a fine microstructure and high strength vehicle wheels with rapid filling, preventing defects and enabling complex geometries like thinner structures.

Abstract

A casting mold (1) for manufacturing a vehicle wheel has a cavity (2) and a feed zone (3), which is joined to the cavity (2) and through which the molten material is introduced to form the wheel. The ratio or modulus between the smallest cross-sectional area of ​​the feed zone (3) and the volume of the cavity (2) is at least 0.6 mm² / cm³.
