Prevention and Control Measures for Hot Cracking Defects in Resin Sand Steel Castings​ Key Strategies to Mitigate Risks in Thin-Walled and Complex-Shaped Steel Castings Produced with Furan Resin Sand

In recent years, driven by technological innovation and industrial upgrading, the foundry industry has made significant strides in performance, process intelligence, and environmental sustainability.

Furan resin is a general term for resins produced with furan alcohol and furfural as raw materials. Its raw materials are widely sourced and the production process is simple. Furfural is the most basic raw material for manufacturing. It comes from agricultural and sideline products such as cottonseed husks, rice husks, corn cobs and corn stalks.

3D printing technology has brought about a revolution in casting technology, and its applications are becoming more and more widespread. In this article, we will explore the advantages of 3D printing resins and their principles.

The temperature is low in winter, and alkaline phenolic resin is more significantly affected by temperature than other modeling resins. Some manufacturers will have high resin addition, low sand mold strength, and even affect production, and doubt the performance of alkaline phenolic resin. Combined with the use of alkaline phenolic resin under low temperature conditions in northern regions, the impact of various temperatures and sand temperatures on alkaline phenolic resin can be reduced through the reasonable selection of resins and curing agents, as well as effective management of the production site. Let's take a look at how to do it!
