Manufacturing Process Explained by a Nitrided Screw Manufacturer
In the high-pressure world of plastic extrusion and injection molding, the screw is the component that bears the brunt of every cycle. As a Nitrided Screw Manufacturer , we often get asked: “What exactly happens in the furnace to make steel this tough?” Understanding the manufacturing process isn't just for engineers; it’s for every manufacturer who wants to ensure their machinery doesn't fail when the production schedule is tight. Step 1: Selection of High-Grade Alloys The journey of a high-performance screw begins with the raw material. Most nitrided screws are crafted from specialized alloys like EN41B (Musco) or 38CrMoAlA . These steels are chosen because they contain aluminum, chromium, and molybdenum—elements that have a high affinity for nitrogen. While a Hardened Screw Manufacturer might focus on through-hardening tool steels like D2 or H13 (which are hard throughout), we focus on materials that allow for a tough, flexible core and an incredibly hard exterior "c...
