Laser coding (laser marking) machines generate a concentrated beam inside a gain medium—such as fiber, CO₂ or crystal—then steer it with fast galvanometer mirrors and focus it to a micron-scale spot on the product surface. Laser coding is achieved by removing material or a coating from the product or packaging, or by changing the surface of the substrate. In each case, the code is permanent.

Laser marking is the placement of the information on the surface with little to no penetration. Engraving refers to placing the information with much more force to reach under the surface of the material.

A laser coder is an industrial machine that uses a focused laser beam to permanently mark products with information like dates, batch numbers, barcodes, or logos—without using ink or physical contact. These systems are widely used in high-speed manufacturing environments such as food, beverage, pharmaceutical, and electronics industries. Laser coders are valued for their durability, precision, and eco-friendliness, as they require no consumables like ink or ribbons.

Choose laser marking if you need:
-Permanent, high-quality marks resistant to abrasion, chemicals, heat, and tampering – ideal for traceability, barcodes, and logos.
-A clean, consumable-free process with low long-term costs and minimal maintenance.

Choose CIJ (Continuous Inkjet) if you need:
-A versatile, fast, and cost-effective solution for multiple substrate types—including curved or porous surfaces.
-Lower upfront investment when permanent marking isn’t critical, such as for date/lot coding.
