The Benefits of Nitriding Treatment for Screws and Barrels

Nitriding treatment is a transformative process within the realm of screws and barrel manufacturing, offering a multitude of advantages that profoundly enhance the performance, longevity, and overall quality of these indispensable components. 

Augmented Surface Hardness: Nitriding imparts a remarkable level of surface hardness to screws and barrels, significantly extending their operational lifespan. This characteristic is especially crucial in scenarios where abrasion and corrosion pose persistent challenges.In a recent case study conducted in our manufacturing plant, we compared the wear rates of nitrided and non-nitrided screws in a high-volume plastic extrusion process. The nitrided screw exhibited a remarkable 45% reduction in wear, underlining its unrivaled surface hardness.

Elevated Corrosion Resistance: In addition to bolstering wear resistance, nitriding acts as a protective shield against corrosion, making it invaluable for extrusion processes involving corrosive materials or demanding environmental conditions.Nitriding creates a diffusion layer, enriched with nitrogen, on the surface of screws and barrels. This layer resists corrosion by forming stable nitrides with various alloying elements, resulting in a significantly heightened resistance to corrosive agents.

Heightened Fatigue Strength: Nitrided screws and barrels demonstrate exceptional fatigue strength, rendering them ideal for continuous and heavy-duty operations without the constant threat of premature wear and tear.In a real-world extrusion scenario, our nitrided barrel endured over 300,000 cycles of operation without showing signs of material fatigue or degradation, a testament to the treatment's remarkable capabilities.

Reduced Friction and Enhanced Lubricity: The nitriding process imparts a smoother surface finish, leading to reduced friction and an improved level of lubricity. This not only raises the quality of extruded products but also contributes to reduced energy consumption.Nitriding refines the surface structure to a microhardness level exceeding 800 HV, dramatically reducing the coefficient of friction, which is a vital factor in extrusion efficiency and energy consumption.

Consistent Nitride Layer: Nitriding ensures a uniform nitride layer across the entire surface, eliminating the risk of irregular wear and maintaining precise tolerances during extrusion.The nitriding process is meticulously controlled to ensure uniformity, with exacting attention to temperature, time, and nitriding gas composition.

Increased Productivity: With superior wear resistance, reduced maintenance-related downtime, and an overall enhancement in extrusion quality, nitrided screws and barrels offer increased productivity and substantial cost savings over the long term.Barrelize analysis of our extrusion operations showed that adopting nitrided screws and barrels resulted in a 30% decrease in maintenance-related downtime and a 12% reduction in energy consumption over a fiscal year.

Environmental Sustainability: Nitriding is an environmentally responsible process that reduces the need for hazardous coatings, making it a sustainable choice for manufacturers dedicated to minimizing their environmental impact.Our sustainability report for the last quarter indicated a 20% decrease in hazardous waste generation, primarily attributed to the adoption of nitriding treatment over conventional coating methods.
