Importance of lubrication in aluminum ends with pull tabs

In the manufacturing industry of aluminum ends with pull tabs, like those used in beverage and food cans, lubrication is a critical factor to ensure product quality and efficient machine operation.

In this article, we explore how effective lubrication with specialized lubricants can make the difference between a stable, productive line and one plagued with failures, waste, and food safety risks.

The challenge of high-speed lubrication

During the stamping and forming of ends, the tools operate at high speed and with extreme precision. Under these conditions, friction between the aluminum piece and the cutting and forming tools can lead to several problems:

• Accelerated tool wear: Without proper lubrication, tools wear out faster, leading to premature failures, unplanned production stops, and higher maintenance or replacement costs.
• Defects in the ends: Burrs, cracks, or deformations in the final product are not just aesthetic issues but can impact the functionality of the packaging, increasing the production rejection rate.
• Lubricant residue contamination: If the lubricant is not formulated to evaporate or degrade completely, it can leave residues on the ends, directly compromising food safety and potentially leading to product recalls or regulatory sanctions.

Why is residue prevention important?

In a food production environment, any contact between the lubricant and the final product must be anticipated, controlled, and, above all, safe. Any lubricant residue could result in a market recall or customer perception issues. Moreover, if the lubricant is not food-grade, it poses a contamination risk for packaged products.

For this reason, it is essential to use food-grade lubricants, certified under standards like NSF H1, which allow incidental contact without posing a health risk.

A specialized lubricant, specifically designed for forming processes in the food industry, should not only protect the tooling but also evaporate completely or leave a clean surface that meets the highest standards.

Strategic lubrication to transform your process

The lubricant you choose within your plan impacts more than you might realize. This step, though often invisible to the final consumer, is crucial to maintaining product integrity and process quality.

Choosing the right lubricant and adopting a strategic lubrication approach tailored to the needs of your end-forming process not only helps protect your equipment but also ensures a cleaner, faster, and more efficient production process. The benefits are clear:

• Longer tool and equipment life, reducing maintenance time and costs.
• Reduced scrap and higher finished product quality.
• Regulatory compliance, ensuring the ends are safe for food consumption.
