Reversed engraving details

Deep engraving details:


Laser deep engraving is used to create permanent and precise markings on a variety of metals, such as stainless steel, brass, Copper, and Sterling silver. The process involves using a high-powered laser to remove material from the surface of the object being engraved, creating a deep, long-lasting mark.

The laser used for deep engraving is typically a fiber laser, which can produce extremely focused and intense beams of light. The laser beam is directed onto the surface of the metal, where it heats and vaporizes the material, creating a deep and precise mark.

One advantage of laser deep engraving is its ability to create intricate and detailed designs with a high level of accuracy and precision. The depth and clarity of the mark can be adjusted based on the material being engraved and the desired outcome.

Generally, our products have a engraving depth of 0.8-1mm, which ensures the three-dimensionality and permanence of the pattern. Our products have a 100-year warranty, if the pattern scratches off or is completely worn out during this period, please contact us and we will send you a new one immediately.

Reversed engraving details:


Same as deep engraving, reversed engraving is to remove the unnecessary parts, so as to preserve the required pattern on the metal surface. It also has a depth of 0.8-1mm and is still durable.

However, the working time of reversed engraving is generally much longer than that of surface deep engraving. Generally speaking, depending on the size of the workpiece engraving area, it takes an average of 2-3 hours to complete, and it has a more perfect three-dimensional effect than deep engraving.

Therefore, reversed engraving is completely in a higher grade rather than the  deep engraving.
