Aluminum alloy die casting has significant potential for development in automotive manufacturing.

In the automotive industry, many challenges—such as enhancing performance, conserving energy, reducing costs, and minimizing pollution—are inextricably linked to the critical issue of lowering vehicle weight. One of the most effective approaches to achieving this goal is material substitution; replacing cast‑iron components with aluminum alloy castings—produced using various casting processes—is a particularly advantageous choice.

Die-Casting Mold Management and Maintenance Specifications

Strengthen die‑casting mold management to ensure proper maintenance, guarantee smooth production and product quality, extend mold service life, and reduce costs. Die‑casting mold maintenance personnel must conduct regular inspections—once per month—and maintain detailed records. Additionally, thorough documentation is required whenever cores are repaired or replaced.

How can the common defects of porosity and shrinkage porosity in aluminum alloy die castings be addressed from a technical standpoint?

Aluminum melt pretreatment: The melting temperature is strictly controlled at 680–720°C, and rotary degassing combined with a 40–60 mesh ceramic filter is employed to remove gases and inclusions from the molten aluminum, thereby reducing its gas content.
