Laser Marking Plastic

laser marking plastic

A plastic laser engraving machine, or non-metal laser marker, uses laser beams to directly generate marks on the plastic surface, including text, codes, labels, characters, lines, numbers, and even colors, without other processing procedures.

The most suitable for marking plastics is the carbon dioxide laser marking machine. Of course, the fiber laser marking machine can also mark most plastic products. The material components, the scope of the marking, and the thickness of the marking material will all affect the final choice of laser markers. The UV laser marking machine can perform ultra-fine marking and special material marking because of its very small focus spot and small processing heat-affected zone. It is the first recommended product for customers with higher marking effects requirements.

If it is used for rapid marking on a factory assembly line, you can consider an online laser marking machine to be embedded in the assembly line system to realize automatic marking.

Laser Engraving Plastic Advantages

High Efficiency

Compared with traditional marking methods, plastic laser marking machine has faster marking speed and higher efficiency.

It uses laser beams to mark directly on the surface of plastic materials without any physical contact, which greatly reduces marking time and cost and improves productivity.

High Precision

During the marking process, the laser beam can accurately control its position and shape, so as to achieve fine marking effect.

Whether it is text, patterns, or barcodes, they can all be presented clearly and finely on the plastic surface.

The advantages of this high-precision marking make it widely used in precision manufacturing fields such as electronic components and mechanical equipment.


During the marking process, the laser beam can remove the oxide layer on the surface of the plastic material, thus forming a clear and obvious mark.

This very high-definition marking effect is widely used in industries such as auto parts and plastic products.

For example, in the production process of auto parts, plastic laser marking machines can clearly mark the information and signs on the parts, which is convenient for production, sales, and after-sales service.


Plastic laser engraving machine is a very important laser equipment, with high efficiency, precision, and clarity, and is widely used in plastic products, electronic components, mechanical equipment, auto parts, and other industries.

First of all, it can be used for product identification and traceability. By engraving the product name, model, production date, and other information, it is convenient for consumers to identify and trace the source of the product. In addition, laser marking can also realize the engraving of serial numbers and batch numbers, as well as the generation of barcodes and QR codes, which provides convenience for logistics management and anti-counterfeiting traceability.

Secondly, laser marking can also be used for brand promotion and design. It can engrave trademarks, logos, and various artistic decorative patterns to enhance the beauty and uniqueness of the product.

In addition, laser marking can also be used in safety certification and anti-counterfeiting measures, such as engraving anti-counterfeiting marks and quality certification marks to ensure product quality and credibility.

Laser Engraving Plastic Project Ideas

Plastic Animal Ear Tag Marking

Laser marking QR codes and digital information on animal ear tags will not cause wear to the products. The marks are clear and beautiful, permanent, and will not fade or peel off.

Lamp Holder

Equipped with a rotating lamp holder fixture, all angles of the curved surface can be marked with high precision and fast speed.

Packaging Bags

The plastic laser marking machine can print trademarks, production dates, batch numbers, barcodes, and other information on the packaging bags, to realize the identification and traceability of the bags.

PVC Pipe

The laser marking machine for plastic can also be used with production lines for the automatic marking of PVC pipes, saving a lot of labor and costs and improving efficiency.

Laser Engraving Machine for Plastic


Which types of plastic are suitable for laser marking?

Laser marking is suitable for most common plastic materials, including polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC), etc. Different types of plastics may require different types of laser equipment or parameter settings.

Will the fiber laser marking machine burn the plastic when marking?

The fiber laser marking machine will not burn the plastic when marking on plastic. The output power of the fiber laser marking machine is generally not high. As long as the parameters are adjusted properly, the laser will only evaporate a thin layer on the plastic surface without burning it. But fiber laser is only suitable for part of the plastic.

Can laser marking be used for color marking on plastic?

Usually, laser marking on plastics is a single-color mark, which is mainly achieved by changing the color of the material surface or creating contrast. If colored marking is required, consider using dyes or additives to achieve this.

How to adjust the parameters for laser marking plastic?

First, set the power, speed, and frequency to the middle value, and then adjust them to high and low. If you want to make deep and black colors, generally adjust the power to high, and the speed and frequency to low. However, plastic is prone to blistering, so it depends on the specific material of your plastic. You can only try it yourself slowly. The power and frequency can be adjusted every five values, and the speed can be adjusted every five hundred values. Two are fixed at each adjustment, and only one parameter is adjusted.
