Integration of CAD and rapid manufacturing for sand casting optimisation

TL;DR

This paper discusses integrating CAD and rapid manufacturing to optimize sand casting, reducing development time and costs by aligning simulation geometry with physical tooling, enabling thinner walls without compromising quality.

Contribution

It introduces a new rapid prototyping process that improves sand casting tooling, aligning simulation models with actual manufacturing, and allowing for thinner, reliable castings.

Findings

Reduced wall thickness to 4mm

Aligned simulation geometry with physical tooling

Lowered manufacturing costs and time

Abstract

In order to reduce the time and costs of the products development in the sand casting process, the SMC Colombier Fontaine company has carried out a study based on tooling manufacturing with a new rapid prototyping process. This evolution allowed the adequacy of the geometry used for the simulation to the tooling employed physically in the production. This allowed a reduction of the wall thickness to 4mm and retained reliable manufacturing process.
