The aluminum extrusion industry is experiencing a surge in demand driven by growth in construction, transportation, and renewable energy sectors. Manufacturers are striving to meet higher quality standards while ensuring operational efficiency. One critical component in this process is the run out roller cover.

These covers play a pivotal role in maintaining the integrity of aluminum profiles during high-temperature extrusion, preventing surface damage, and ensuring smooth handling. However, many extruders unknowingly compromise on quality by using substandard roller covers, often falsely marketed as high-grade solutions. This article explores the risks of such choices and highlights Albarrie’s solutions for overcoming these challenges.

The Role of Roller Covers in Aluminum Extrusion

Conveyor roller covers act as a protective buffer, ensuring freshly extruded aluminum profiles remain undamaged during processing. This protection is essential as aluminum exits the press at temperatures of 750–930°F (400–500°C), making it vulnerable to marking, scratches, and deformation.

High-performance roller covers contribute to uninterrupted production, smooth handling, and consistent product quality. They are indispensable for maintaining operational efficiency in an industry where precision and reliability are paramount.

The Hidden Costs of Substandard Materials

While generic roller covers may appear cost-effective, they often come with hidden expenses:

• Heat Degradation: Many products labeled as “heat-resistant” fail to withstand the high temperatures of aluminum extrusion. Albarrie’s testing revealed that certain generic covers begin to degrade at just 392°F (200°C) and undergo complete thermal degradation by 752°F (400°C).
• Surface Defects: Inferior materials often leave marks on aluminum profiles, leading to rejected products and lost revenue.
• Frequent Replacements: Low-quality covers wear out quickly, necessitating more frequent replacements and increasing downtime.
• Safety Risks: Material failure under stress can create hazards for workers and equipment.

These issues stem from deceptive practices, where roller covers are marketed as high-performance but are composed of blended, recycled, or low-grade fibers rather than pure meta-aramid or para-aramid materials like Kevlar® or Nomex®.

Albarrie: A Proven Solution for Excellence

Albarrie stands out as the only ISO-certified North American manufacturer of high-performance roller covers. Unlike competitors that rely on imported, unregulated materials, Albarrie maintains full control over its supply chain, sourcing premium virgin fibers and employing proprietary manufacturing techniques.

Key Features of Albarrie’s Roller Covers:

• Durability: Designed to endure extreme thermal and mechanical stresses, reducing wear and tear.
• Thermal Stability: Withstands temperatures exceeding 1000°F (548°C).
• Non-Marking Surfaces: Protects aluminum profiles from damage.
• Custom Solutions: Tailored to meet specific operational needs.

Superior Performance Backed by Rigorous Testing

Albarrie’s Defender™ Series Roller Covers were tested against generic alternatives using Thermogravimetric Analysis. Results showed that Albarrie’s covers endured up to 932°F (500°C) without degradation, while competitors’ products began degrading as early as 392°F (200°C) and failed completely at 752°F (400°C). This resilience translates into fewer replacements, reduced downtime, and enhanced safety.

Tailored Solutions for Every Operation

Albarrie offers two product lines to meet diverse customer needs:

• Defender™ Series: Premium, high-temperature-resistant covers for demanding applications.
• Valiant™ Series: Budget-friendly options for less intensive environments.

Additional offerings include separator rollers, slat and beam covers, spacer bar sleeves, and heat-protective tape, ensuring comprehensive solutions for aluminum extrusion facilities.
