Solutions for Effective Sand Temperature Control in Green Sand Casting

A Close Look at How Casting Shapes the Heart of Power Machinery.

Analyzing the Characteristics and Application Scenarios of Different Core-Making Technologies.

Foundry coatings are vital in casting production, primarily preventing surface sand adhesion and enhancing inner cavity cleanliness. Advanced functional variants like anti-veining, anti-sintering, and chill coatings are now widely used.

Innovative Solution Empowers Filtration of Large Cast Iron Components, Enhancing Casting Quality and Production Efficiency.

In casting production, casting waste caused by casting defects such as non-metallic inclusions reduces the profits of casting companies. Especially in the past two years, with the increase in the price of cast pig iron and the maturity of synthetic casting technology, foundries have widely used scrap steel and scrap iron as smelting furnace materials to reduce costs. Although the return charge can reduce costs, the return charge has not been fully sanded and shot blasted, and its sand content is too high, resulting in a large amount of difficult-to-clean slag during the smelting process. At the same time, the source of scrap steel is complex and is often mixed with non-metallic inclusions, which further increases the inclusions and slag in the molten iron, thereby causing defects such as slag inclusions, pores, and slag holes, which seriously affect the quality of castings. So, how to solve this kind of problem? The use of filters can effectively reduce or eliminate various non-metallic inclusions and purify liquid casting alloys.

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!
