Plant managers rarely notice screw wear the moment it begins — it shows up gradually, as small dips in output, minor quality issues, or slightly longer cycle times. By the time the problem is obvious, the machine may have been running below capacity for weeks or months. Recognizing the early warning signs of screw wear allows engineers and procurement teams to plan replacements proactively, rather than reacting to a costly unplanned shutdown. This article walks through the seven most common indicators that a screw and barrel set has reached the end of its useful service life. 1. Declining Output Without a Process Change If your machine's throughput has dropped even though the material, temperature settings, and cycle parameters haven't changed, screw wear is one of the most likely causes. Why This Happens As the screw flights wear down, the clearance between the screw and barrel increases. Molten material can slip backward through this gap instead of being pushed forward effici...

We make abiding Nitrided screws that are affordable.  Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. A Nitrided Screw has a plethora of manufacturing capabilities. The applications of nitrided screws are injection molding, extrusion molding, and blow molding. By using high-quality grade nitriding steel, with 72 hours of nitriding process, the nitrided layer will help the screw to get better performance by being corrosion and abrasion-resistant. Nitrided screws have a very good wear resistance until the sur...
