About Our Conical Screw Repair Services

At Screw And Barrel Repair, our Conical Screw Repair service is meticulously designed to restore your industrial screws to their peak operational efficiency. The process begins with a comprehensive evaluation of your conical screw, utilizing advanced diagnostic techniques such as ultrasonic testing and metallurgical analysis. This initial assessment helps identify the extent of wear and damage, pinpointing areas that require critical attention such as thread erosion, root radius wear, or flight degradation.

Following the assessment, the repair process involves precision machining and re-coating techniques. We employ CNC (Computer Numerical Control) machining to accurately remove damaged layers and reshape the screw to original design specifications. This is crucial for maintaining the screw’s essential clearances and tolerances, which are vital for efficient plasticizing and melt quality. For screws that have suffered extensive wear, we utilize weld overlay and thermal spray coatings, applying materials like tungsten carbide or chromium carbide to significantly enhance the wear resistance of the working surfaces.

The next step involves polishing and finishing, which is not just about aesthetics but is essential for achieving the smooth, frictionless surface needed for optimal material flow and pressure consistency. Our final inspection includes precise measurements and quality checks to ensure that every repaired screw meets stringent industry standards and performs effectively in demanding production environments.

Finally, we conduct a rigorous performance testing phase, where the repaired screw is tested under simulated working conditions to validate its functionality and performance enhancements. This ensures that every conical screw we repair delivers improved throughput, energy efficiency, and longevity, significantly reducing your machine downtime and operational costs. At Screw And Barrel Repair, we are committed to providing a repair service that not only restores but often improves upon the original performance characteristics of your equipment.
