Using Software to Define Fast, Accurate Casting Set-Ups

March 6, 2017
Using simulation software results directly in the rigging process produces a more accurate casting set-up than manual techniques, in a much shorter time period. This integrated approach reduces overall costs and lead times.

Technology uses the progression of solidification, along with pattern-recognition algorithm, to determine feeding paths on a casting

The correct design of gating and risering is essential for a foundry to be successful in the production of high-quality castings. Designing efficient gating and risering systems is difficult for foundry engineers because of a number of common factors.

The general design process consists of five steps: Simulation of the ‘naked’ casting; Riser design; Gating system design; Rigging geometry creation; Verification via CFD/solidification simulation. Following here is a detailed look at this process, using a commercial ductile iron casting.
