Cermark

Creating a permanent, readable mark on metal can be challenging for shops that rely on CO2 laser systems. A CO2 laser on its own cannot produce a durable dark mark on bare metals such as stainless steel or raw aluminum. To get a lasting result, you either apply a laser marking compound to the part or use metal that has been engineered for CO2 laser marking.

Both approaches work, but they serve different needs. Your choice depends on the material you’re working with, the required durability, and the volume of parts you process.

Pre-Treated Materials: DuraBlack and AlumaMark

For high-volume flat tags and plates, pre-treated metal is a straightforward option. These materials are built to respond consistently to a CO2 laser, and they remove the steps of spraying, drying, and rinsing.

DuraBlack - DuraBlack is designed for harsh environments. It is a CO2 laser-markable aluminum product that meets requirements such as MIL-STD-130 and MIL-DTL-15024F. It holds up to abrasion, chemicals, UV exposure,

Cermark is a valuable tool for permanently marking a variety of materials with your laser engraver. However, avoiding common mistakes will ensure clean, durable marks and prevent wasted materials. 

Laser marking with Cermark products is a permanent and professional way to personalize or identify products. While the process can be straightforward, several common errors can hinder the quality of your engravings. Here are the key pitfalls to watch out for when using Cermark products.

Inadequate Surface Preparation

Properly preparing the surface before applying Cermark is fundamental. Contaminants like dust, oil, or fingerprints can significantly impede the adhesion of the Cermark solution to the material. This often leads to inconsistent marking or areas where the Cermark doesn't bond at all, particularly on metals and ceramics. Ensure the surface is thoroughly cleaned with a suitable degreaser or cleaner and is completely dry before applying Cermark. When using a GCC Laser Pro machine, clean
