Laser Marking Technology for Aluminum Cans | TEYU S&A Chiller Manufacturer

Summer is the peak season for beverages, and aluminum cans hold a 23% market share of all packaged beverages (based on 2015 statistics). This indicates that consumers have a greater preference for beverages packaged in aluminum cans compared to other packaging options.

Among the Various Labeling Methods for Aluminum Can Beverages, Which Technology Is Most Widely Used?

Laser marking technology has long been deeply ingrained in the beverage industry. It offers flexibility and helps customers accomplish challenging coding tasks while reducing costs, minimizing material consumption, generating no waste, and being highly environmentally friendly. It is applicable to most packaging types and is capable of reproducing high-resolution fonts and graphics.

In the case of coding applications for canned beverages, a laser generator produces a high-energy continuous laser beam. When the laser interacts with the aluminum material, the atoms in their ground state transition to higher energy states. These atoms in higher energy states are unstable and quickly return to their ground state. As they return to the ground state, they release additional energy in the form of photons or quanta, converting light energy into thermal energy. This causes the aluminum surface material to melt or even vaporize instantly, creating graphic and text markings.

Laser marking technology offers fast processing speed, clear marking quality, and the ability to print various texts, patterns, and symbols on the surfaces of hard, soft, and brittle products, as well as on curved surfaces and moving objects. The markings are non-removable and do not fade due to environmental factors or the passage of time. It is particularly suitable for industries that require high precision, depth, and smoothness.

Essential Temperature Control Equipment for Laser Marking on Aluminum Cans

Laser marking involves converting light energy into heat energy to achieve successful marking. However, excessive heat can lead to blurry and incorrect markings. Therefore, precise temperature control is necessary to ensure clear and accurate marking.

Teyu UV laser marking chiller provides precise temperature control with an accuracy of up to ±0.1℃. It offers two modes: constant temperature and intelligent temperature control. The compact and portable design of laser chillers allows for easy mobility, providing better support for precise laser marking. It improves the clarity and efficiency of the markings while prolonging the lifespan of the laser marking machine.
