Introduction to Nitrided Barrels
Nitrided barrels are crucial components in various industrial applications, especially in the plastic processing and extrusion industries. A nitrided barrel is a metal barrel that has undergone a nitriding process. Nitriding is a heat - treating process that diffuses nitrogen into the surface of a metal to create a case - hardened surface. This process significantly enhances the barrel's hardness, wear resistance, corrosion resistance, and fatigue resistance.
In the plastic processing industry, nitrided barrels are used in injection molding machines and extruders. They come into direct contact with molten plastics under high pressure and temperature. The improved properties of nitrided barrels ensure a longer service life, better product quality, and more stable production processes. In China, there are many excellent suppliers of nitrided barrels, and here are the top 10.
