Overall, plastic laser marking technology boasts numerous benefits and promising applications. As laser technology advances, it is poised to play a vital role in plastic processing by offering reliable and efficient solutions for product quality and identification needs.
How to Selection a Laser Marking Machine for Plastic?
Laser marking machines are extensively utilized in today’s manufacturing industry for marking and identifying various materials. When it comes to plastic products, selecting the right laser marking machine is pivotal. Among the diverse options available in the market, the most prevalent choices are fiber laser marking machines and UV laser marking machines. Below, we will delve into the characteristics and suitability of these machines to assist you in making an informed decision.
The fiber laser marking machine is an efficient, stable, and durable equipment ideal for marking most plastic products. It excels in achieving high-speed, high-precision marking with enduring clarity. Notably, this machine stands out in marking depth and speed, making it particularly suitable for long-term operations and mass production.
On the other hand, the UV laser marking machine utilizes a high-energy UV laser to generate exceptionally high energy density within a minute focal spot range, enabling detailed and precise marking on plastic materials. Additionally, the UV laser marking machine typically features a compact design and lower energy consumption, making it well-suited for energy-conscious production environments.
When selecting a plastic laser marker, various factors come into play, such as desired marking effects, production speed, material type, and cost. For simple markings, a fiber laser marker may suffice, while complex plastic processing or higher energy consumption requirements may necessitate a UV laser marker.
In conclusion, whether opting for a fiber laser marker or a UV laser marker, thorough consideration of all factors based on the specific situation is crucial. Only by understanding your requirements and comprehending the distinct characteristics of different laser markers can you make the most suitable choice to enhance production efficiency and product quality. This article aims to guide you in selecting the ideal plastic laser marker for your needs.
The picture shows you the comparison of using a fiber laser marking machine and a UV laser marking machine to mark the same plastic injection molded part. When laser marking black on colored plastic, the fiber laser can mark a high-contrast dark black, while the UV laser marking machine shows a gray-black color.

When laser marking white on black polymers, a fiber laser can laser mark a high-contrast white mark on the PA+GF injection molded sample shown on the left, while a UV laser can mark a more delicate light white mark (1.5% laser marking additive for the PA+GF molded part)
Comparison Of The Advantages And Disadvantages Of Fiber Laser Marking Machines And UV laser Marking Machines When Applied To Plastic Marking
Fiber laser marking machines and UV laser marking machines are commonly utilized technologies in plastic marking. Fiber laser markers excel in fine marking, high speed, and efficiency. They can precisely create clear marks on plastic surfaces, making them ideal for applications that demand high-precision marking and mass production. However, fiber laser marking machines may encounter issues with large heat-affected areas when processing specific special plastic materials, leading to potential deformation or damage during marking.
On the other hand, UV laser marking machines offer advantages such as low radiation heat, minimal heat impact, and reduced damage to plastic surfaces during marking, making them suitable for processes with stringent requirements for plastic materials. Despite these benefits, the applicability of UV laser marking machines to plastic materials is somewhat limited, requiring the selection of suitable materials for marking. They may not match fiber laser marking machines in terms of marking speed and efficiency.
In summary, the choice between fiber laser marking machines and UV laser marking machines should be guided by the specific plastic materials and marking needs at hand. Fiber laser markers are well-suited for most plastic marking scenarios, while UV laser markers are better suited for processes with specialized requirements for plastic materials. In practical applications, selecting the appropriate marking equipment based on product specifications and budget constraints ensures optimal marking results. For instance, when marking a white pattern on a colored polymer plastic product, a UV laser marking machine is essential.
The following image illustrates the marking effects of a UV laser machine and a fiber laser machine when marking the same sample with DOME’s laser marking additive(white laser marking on colored polymer):
The left picture shows the comparison between using a UV laser machine and a fiber laser machine when we want to laser mark white on colored polymers. It can be clearly seen that the fiber laser machine can only mark black. So when you want to laser mark white on colored polymers, you must choose a UV laser machine.
How To Set The Parameters Of The Laser Machine For The Best Marking Effect?
To achieve the best marking effect with a laser machine on plastic materials, it is essential to set the parameters correctly. Follow these guidelines to optimize plastic laser marking:
- Laser Power, Speed, and Frequency: Adjust these settings based on the type and thickness of the plastic. Higher power can create deeper marks, but be cautious of overheating. Moderate scanning speed ensures quality marks without thermal damage. Adjust spot size for uniformity in mark size and depth.
- Marking Frequency: Customize the marking frequency for clear and deep marks. Choose appropriate scanning modes like linear, bidirectional, or turbine scanning based on requirements.
- Working Distance: Adjust the working distance to maintain clarity and depth in marks.
- Test Marks: Before actual marking, conduct test marks on sample materials to fine-tune laser settings and techniques. Continuous testing and optimization are key to achieving the desired marking quality.
- Consultation: If facing challenges, seek advice from laser marking technology experts or manufacturers for guidance and support in optimizing the marking process.
By implementing these adjustments and recommendations, you can enhance the laser marking process on plastics, ensuring high-quality and durable results. These strategies will aid in achieving optimal marking outcomes on your fiber laser marking machine.
