You might be asking what the difference is between laser engraving and laser etching if you are new to laser technology. In addition, more crucially, which one is most suited to your needs?
The major distinction between laser etching as well as laser engraving is that etching burns the micro area to produce raised patterns, whilst engraving eliminates material to produce deep marks. High heat is used in both techniques to leave permanent marks on metal parts.
For part tracking, both procedures are widely utilised. Let us take a closer look at each method to discover which Laser Engraving Fort Worth is better for which application.
The Laser Etching Method
When etching is done, the laser warms and alters the material’s tiny surface. The laser etched material stretches and develops texture as a result.
Laser etching produces black and white lines and is the most effective way of marking most materials indefinitely. Because etching uses less energy from the beam, it is quicker than engraving.
You Require Laser Etching For The Following Reasons:
- Except for stainless steel, your component is made of metal.
- You would like the quickest laser process possible.
- You want a laser that is less expensive and uses less power.
- Prior to non-abrasive procedures such as protective coatings, e coating, and heat-treating, you must incorporate laser marking.
The Laser Engraving Procedure
The laser burns up a tiny layer of the substance to form a tracking code using the engraving procedure. This is achieved by directing a highly focused laser beam at your component.
Laser etching delves into the material rather than generating a micro-surface that is lifted above it. Engraving depths of up to 500 microns are possible.
What Are The Benefits Of Laser Etching And Laser Engraving?
If you have ever tracked components with dot drilling, inkjet printing, or print labels, you are well aware of the significant maintenance and disposable expenses associated with these marking systems. Furthermore, you have undoubtedly had to cope with erratic outcomes as a result of a faulty marking system.
What Etching And Engraving Can Do For You
- Laser Engraving Fort Worth encodes data that cannot be removed from the product over its lifetime.
- Laser Engraving Fort Worth has a high resolution, which means many data can be crammed into a tiny space (particularly if data matrix codes are used).
- Laser cutting and embossing machines are low-maintenance devices.
- No consumables are required for fibre and CO2 laser systems.
- Pulsed fibre lasers consume extremely little power.
Which Industries Use Laser Engraving And Engraving?
Many of our customers use Laser Engraving Fort Worth to acquire a large amount of data for their tracing program. Some of them use this knowledge to improve their production processes as well.
These laser methods are used to create a variety of barcodes, notably QR codes and data matrix patterns, as well as serial numbers and numeric values. Others prefer to brand their items by imprinting their company logo on the parts.
The Most Prevalent Industrial Uses Are Listed Below.
Supplier traceability has long been a need for automakers. They were among the first to use the data matrix coding to identify individual parts as they entered the final production. To assure conformance and impose accountability, the components are scanned at key points across the value chain. They now demand that part verification be completed as soon as feasible.
Primary Metals Industry
Hot and cold roll plants, Smelters, die casters, and separators were introduced later in the game, owing to the demands placed on them by their auto clients. They also discovered that the information gleaned from their internal tracing program assisted them in optimising their procedures. Others employed laser marking to outperform competitors by producing items that met stringent environmental criteria.
Other Laser Marking Techniques In Industry
In industry sectors, laser etching and engraving are not the only options. Although much less popular, laser annealing seems to be the only way to brand carbon steel and chrome-plated work piece material.
The reason for this is simple: it is the only way to make lasting markings while keeping the part’s natural tensile strength.
Instead of etching, laser annealing warms the metal. Through a chemical reaction called as oxidation, this procedure leaves a black mark beneath the surface.
Annealing differs from etching in that it is a chemical process that does not involve melting the material’s surfaces. To the naked eye, there is not much of a difference.
