In casting processes, besides molds and molten metal, sand cores play a crucial role in determining whether the internal structure of a casting meets design requirements.
Especially for hollow brass products such as faucets, water meter housings, and valves, sand cores are an essential part of the casting process.

As manufacturing continues to move toward automation and intelligent production, traditional labor-intensive casting methods are gradually being replaced by automated casting systems.
Automated casting has become a key solution for improving competitiveness in the production of brass faucets, water meter housings, valves, and sanitary hardware.

This comprehensive guide introduces the most common casting processes, explains how each method works, and highlights their advantages, limitations, and typical applications. Whether you are a beginner, an engineer, or a factory owner looking to optimize production, this article will help you understand the essentials of modern metal casting.

Low Pressure Casting vs Gravity Casting: What’s the Difference?

In the modern foundry industry—especially in brass sanitary hardware, automotive parts, and precision metal components—casting technology plays a decisive role in product quality and production efficiency. Among all casting methods, Low Pressure Casting and Gravity Casting are the two most widely used processes.

Although both methods shape molten metal inside a metal mold, they differ significantly in metal flow behavior, process control, casting quality, and applicable products. This article provides a clear and professional comparison to help manufacturers choose the most suitable casting process for their production needs.
