What Is Gravity Casting
Gravity casting—also known as gravity die casting—is a widely used and highly reliable casting process in the brass industry. It is especially popular for manufacturing brass faucets, valves, water meter bodies, and sanitary hardware due to its stability, consistency, and cost-effectiveness.
For beginners who are new to casting equipment or faucet production, this article provides a clear and comprehensive introduction to what gravity casting is, how it works, and why it matters for your factory.

What Is Low Pressure Casting?
Low pressure casting has become one of the most important and reliable manufacturing technologies in the brass sanitary ware and water-meter industries. From brass faucet bodies to brass valve housings and water meter shells, low pressure casting delivers higher quality, better consistency, and safer product performance compared with traditional gravity casting.If you are planning to improve your brass casting quality or build a new faucet production line, understanding low pressure casting will help you make the right technical decisions.

What Is a Polishing Machine?
A polishing machine is a mechanical device used to improve the surface quality of metal parts by removing scratches, oxidation, welding marks, tool paths, and minor defects through controlled friction. It operates using polishing wheels, abrasive belts, polishing pads, or buffing compounds to achieve various finishes—from matte to mirror finish.
