Maintenance Tips Recommended by Leading Nitrided Barrel Manufacturers
In the high-stakes world of plastic extrusion and injection molding, the barrel is the silent workhorse. It endures relentless thermal cycling, high internal pressures, and the abrasive flow of molten polymers. While nitrided barrels are a popular and cost-effective choice for general-purpose applications, their longevity is entirely dependent on how they are treated. Any leading Nitrided Barrel Manufacturer will tell you that maintenance isn't just about cleaning; it’s about preserving the metallurgical integrity of the surface. Understanding the "Nitrided" Surface To maintain a barrel, you must first understand its anatomy. A nitrided barrel is created by diffusing nitrogen into the surface of a steel alloy (usually EN41B), creating a hard, wear-resistant "case." This layer is incredibly tough but thin—typically ranging from 0.4mm to 0.7mm. The biggest risk cited by a Nitrided Barrel Manufacturer is "breakthrough." Once the hard nitrided layer is w...
