How to Choose a Laser Marking Additive for Your Polymers?

By considering these factors and conducting proper testing and evaluation, you can choose a laser marking additive that meets your specific needs and ensures optimal marking results on your plastic polymers.

1. Compatibility

Ensure the laser additive is compatible with the material. Different plastics have different properties, and using incompatible additives may lead to poor results or material damage. DOME™ has developed laser marking additives for multiple plastic polymers, such as PP, PE, PC, PVC, ABS, TPU, PBT, TPR, TPE, HIPS, PA6/PA66, ABS+PC, etc

2. Laser Wavelength

Different additives are optimized for different laser wavelengths. Some work best with UV lasers, while others are designed for fiber lasers. For marking white on colored polymers, a UV laser is recommended. For marking black on colored polymers or marking white on black polymers, a fiber laser is generally recommended. Choose an additive that matches your laser system’s wavelength.

3. Marking Quality

Evaluate the desired quality and effect of marking. Laser additives are created to generate marks that are high in contrast, sharp, and long-lasting. Consider the desired level of permanence, readability, and appearance of the marks.

4. Process Conditions

Consider the process conditions, such as temperature, humidity, and laser power settings. Certain laser marking additives may exhibit superior performance under specific conditions, making it crucial to select an additive that can endure the particular process conditions of your application.

5. Durability

Consider the longevity of the marking and choose a durable additive. It should resist fading and degradation from environmental factors like UV radiation or chemicals. For Example, DOME™ recommends adding 20%-30% PMMA for black keyboard laser marking on ABS materials.

6. Regulatory Compliance

If your polymers are intended for specific industries or applications, such as medical, automotive, or aerospace, make sure that the selected laser additive meets the applicable regulations and standards for those industries. DOME™ laser marking additives have successfully met the testing standards of relevant industries and have been validated and acknowledged by the market.

7. Supplier Support

Consult with laser additive suppliers or equipment manufacturers for guidance. Look for customer reviews, certifications, and technical support to ensure reliable product quality. DOME™ will be your reliable supplier of laser marking additives. We can provide expertise and suggest suitable laser marking additives based on your requirements.

What are the key factors that impact the efficiency of plastic laser marking?

Several factors need to be taken into account, such as the quality of raw materials, the type and quantity of laser marking additives used, the selection of appropriate laser marking machines, and the optimal laser marking parameter settings. Each of these factors can be influenced by multiple variables, making the process of achieving desired results a complex one.

Recommended Plastic Laser Marking Additive Dosages

For DOME laser marking additives, we recommend a dosage of 0.3% to 0.5% for laser marking powder, and 0.6% to 5% for laser marking masterbatch. If there are additional modification additives, such as flame retardant or fiber additions, the amount added should be increased accordingly. However, the actual amount added may vary depending on the cost and laser marking effect standards that need to be met.

The plastic raw materials must be thoroughly dried before adding our laser marking additives

Failure to do so may result in the material dissolving together, rendering the raw material unusable. It's important to note that laser marking additives typically don't require baking. However, laser marking additives that are specifically designed for high melting point plastics can be baked together.

Choice of laser marking machine type

Two types of laser marking machines are commonly used: UV and infrared. UV machines are known for their stable speed and lack of consumables, but they have limitations in their use of certain plastics and high maintenance costs. Infrared machines, such as fiber lasers, are versatile and efficient, with fast operating speeds and the ability to meet various marking requirements across different materials.

Optimizing Laser Marking on Black Plastic: Importance of Natural or Transparent Raw Materials and Avoid Adding any Carbon Black Masterbatch/Pigment

For optimal laser marking on black plastic, use natural or transparent new raw materials instead of recycled materials. Avoid using black coloring agents like black color masterbatch or paste. Instead, use laser marking additives directly. Excessive black coloring agents can interfere with laser light absorption and result in poor marking. If needed, add organic oily black to enhance the blackness, but avoid pigment masterbatches like a black seed or carbon black.

Adjustment of Laser technical parameters

Adjusting laser technical parameters is crucial for achieving the desired level of precision and contrast during the marking process. Expertise is required to balance power, frequency, and scan speed to generate the right amount of heat on plastic surfaces. Even under the same conditions, if the font size is different, necessitates the use of different laser parameters. It's important to conduct multiple tests to find the optimal marking effect. Simply increasing the added amount without adjusting the parameters may lead to blind cost escalation.

Plastic raw materials

The variation in laser marking effects when different plastic raw materials are mixed with laser marking additives. The saturation, sharpness, and definition of laser markings generally appear good when additives are used in materials such as PP, PC, PE, PVC, ABS, and TPU. However, materials like PA6, ABS+PC, and HIPS show somewhat inferior responses to laser marking additives. The image above displays a comparison of the laser marking effects on ABS and ABS+PC when the same amount of laser marking additives and laser machines are utilized.

We have always put quality first

To ensure the quality of our products, the raw materials are subject to strict quality control upon receipt of the goods, and the finished products are also carefully inspected. This involves taking a random sample of the product and then comparing the initial value with the current value in our lab. This process allows us to determine how well the product meets the specified quality requirements. We have a wide range of modern testing equipment that allows us to analyze various parameters for quality control.

Why Use Laser Marking Additives?

Laser marking is a durable and versatile method for marking plastic surfaces, offering benefits such as improved quality control and brand protection. However, not all polymers react the same way to laser marking, and laser marking additives may be necessary to achieve desired results without altering the color or properties of the plastic. When selecting a laser marking additive for your plastic polymers, it is essential to choose one that is compatible with your plastic and that will not affect its properties or performance. DOME Materials offers high-quality laser marking additives tailored to specific needs. Contact us today to learn more about our products and services.

Usage Notice of Laser Marking Additive

  • Laser marking additives are mainly used in injection molding or pelletizing production processes, just mixed evenly with the substrate.
  • Laser marking black or gold on black polymer: We recommend that the raw materials be natural or transparent, and no carbon black or black masterbatch should be added.
  • It is also important to ensure that the laser marking system used is compatible with the additive and to test the mark on a small area before applying it to the entire material.
  • Most laser marking additives do not require baking. It is recommended to dry the raw materials first and then mix our laser marking additives evenly.
  • It is important to follow the instructions for use provided by the additive manufacturer and follow proper disposal procedures.
