Discover Laser Marking Machines for Plastic

Our tools use a variety of laser wavelengths to mark most plastics.

Many plastics can be marked using standard, nanosecond-pulsed MOPA fiber lasers; however, some plastics require UV or green laser technology to achieve optimum results.

Solutions for Laser Marking on Plastics

Plastics are ubiquitous in our culture, being found in millions of products in our homes, our cars, and at our places of work. Because of their widespread use, companies have realized the great need for laser systems to mark and etch these plastics with serial numbers, barcodes, company logos and many other important symbols.

One important aspect to keep in mind when working with plastics is the different kind of ways a laser marking system can be used with the material. Let’s take a look at three key approaches:

• Laser marking – This approach utilizes a laser beam to interact with a material’s surface, creating a slightly changed appearance. Through a process of discoloration, oxidation under the surface of the material turns the surface black or dark gray while leaving the overall surface intact.
• Laser engraving – This method features the removal of a portion of the material’s surface by the laser beam, allowing an exposed cavity to be formed. By utilizing a higher level of heat, the material to be removed is vaporized on contact. The marking of serial numbers and logos on surfaces often utilize this process.
• Laser etching – This technique is a subset of laser engraving and can be performed on diverse materials, such as polymers, metals, and ceramics. During the process, the laser beam uses high heat to melt the surface of the material. This melted material expands to form a raised mark, resulting in a permanent engraving.

Foaming and Color Change for Plastics

One particular form of laser marking on plastics is by way of what is called “foaming” or color change. During this type of laser marking, the plastic utilized is subjected to a controlled burn.

The end result of this procedure is a fairly smooth surface with minimal penetration of that surface. A tan, white or dark-colored mark is left upon the surface following the process, which all depends upon the type of plastic being utilized. During this form of laser marking for plastics, the control of the heat source is highly important.

Fume Extraction System

It is recommended that you use a ventilation unit when laser marking plastic. This will help remove debris, fumes, or gases that are produced during the process. While laser marking plastic is ultimately considered to be cleaner than alternative methods, there are still some emissions that are produced during the process, and this can vary based on the type of plastic produced.

Using a fume extraction unit can help keep your indoor air quality at its best, remove any odors that are produced, and help you comply with any regulations for your location and industry. Our fume extraction units connect with our standard laser systems for easy hookups. Additionally, we have a variety of sizes available so that you can choose one that fits your application.

FAQs on Laser Engraving Plastic

Which industries typically use laser marking machines for plastic?

Laser marking machines for plastic are commonly used to label products, facilitate traceability, adhere to branding guidelines, customize items, and so much more. These tactics are often seen in the following industries and applications:

Does laser marking damage the plastic material?

The process of laser engraving plastic is non-invasive, which means it does not damage or weaken the structural integrity of the item being marked. However, too much heat or power can lead to melting or deformation, so it is important to know the type of plastic being marked and the appropriate parameters that should be used.

What are the benefits of laser marking plastic parts and components?

Laser marking plastic parts is advantageous when you want to create precise, high-quality, long-lasting marks. These same marks are tamper-proof, ideal for product tracing and authentication. The approach also offers high-speed processing and minimal material removal which means that you can efficiently laser mark plastic parts in a timely fashion.  

What type of plastic can be laser engraved?

It is possible to laser engrave a wide range of plastics, including the most common types like ABS, PVC, polyethylene, polypropylene, and acrylics. It is important to note that the effectiveness can vary based on the plastic’s composition, color, and additives. Therefore, we suggest conducting tests on the materials you desire to mark and adjusting settings to achieve the best possible outcome.

It is also possible to mark recycled or reprocessed plastics. Since the composition and quality of recycled plastics can vary, the outcome may be slightly altered as well. In this circumstance, testing will help determine the right parameters to create the mark of your choice.

What are the key considerations for choosing the right laser marking machine for plastic?

When selecting a laser marking machine for plastic, it is important to consider the type of plastic, intended marking effect, production volume, and any regulatory requirements at play. Additionally, you will want to choose a machine based on the characteristics of the material and the desired outcome. Therefore, take into account wavelength, laser power, marking speed, and other aspects.
