Nitriding is a specialized heat-treating process that diffuses nitrogen into the surface of a metal, creating a case-hardened layer that significantly enhances durability and wear resistance. This process is widely used in the manufacturing of screws and barrels, which play a crucial role in applications such as injection molding, extrusion molding, and blow molding.
By using high-quality nitriding steel and subjecting it to a 80-hour nitriding process, the resulting nitrided layer enhances the performance of screws and barrels by making them highly resistant to corrosion and abrasion. This improved surface hardness ensures exceptional wear resistance, allowing the components to maintain their durability until the hardened layer is worn away. The use of nitrided screws and barrels in molding systems not only increases their lifespan but also improves overall efficiency and reliability in high-friction and high-temperature environments.
