Foundry Practice 270

The articles:

Further evaluating iron filter print designs

A follow-up to a 2017 paper that documented qualitative analyses of filter print designs, this paper presents the results of subsequent quantitative analysis and evaluation of several filter print design concepts using casting process simulation software.

Reducing formaldehyde emissions from water-based coatings

With formaldehyde (FH) emission limits tightening in the EU, the release of FH from water-based coatings is under scrutiny. This paper discusses a new generation of FH-free coatings that are designed to help foundries comply with the latest regulatory requirements, without impacting performance.

An investment casting foundry experience in improving degassing and grain refining in molten aluminium alloys

Recent technological developments are raising the performance and lowering the environmental impact of aluminium alloy treatment processes. This paper discusses these improvements as implemented at a foundry in New Jersey, USA, with discussion of the pre-implementation rationale and evaluation process, as well as the achieved technical, economic and environmental benefits.

Melt quality investigation for high integrity aluminium castings

The use of the MTS 1500 process has been demonstrated to improve melt cleanliness in the manufacture of high-integrity aluminium castings. This paper discusses some recent case studies, focusing on high-pressure die casting applications and the use of VMET melt quality assessment to quantify the level of melt quality improvement.

Reclamation of inorganic bonded sand systems towards a more sustainable core production process

This paper presents an innovative process for the effective reclamation of foundry sand from cores made with the SOLOSIL* TX inorganic binding system.

Paradigm shift: an Indian Foundry Experience

Bradken and Foseco have forged a close association in India, working together to create value by improving foundry processes and the development of castings. This paper highlights the outcomes of this joint effort and the benefits of collaboration.
