A Complete Guide to Laser Additive Masterbatch for Plastic Injection Molding

Laser marking additive masterbatch has changed the manufacturing and product identification process. These additives are incorporated into the plastic manufacturing process to enhance the contrast of the plastic with laser marking, enabling accurate and permanent marking of logos, serial numbers, barcodes, and other identifiers. They are extensively used in various applications, including animal ear tags, plastic cables, safety seals, electronics, lighting, automotive and more. In this blog, we discuss what a laser marking additive masterbatch is and provide everything you need to know to make the most of laser marking additives. 

What is a Laser Marking Additive Masterbatch? 

A laser marking additive masterbatch or laser colourant is are specialized colourant to produce high-contrast, durable marks. These additives help in uniform adsorption of laser energy, leading to improved clarity, speed and excellent contrast in marking performance. One of the main benefits of laser marking additives is their ability to produce high-contrast marks without compromising on material integrity, contributing to cost-effectiveness and environmental sustainability. Using a non-contact marking reduces material waste and the need for an ink-based marking. Laser marking masterbatch offers a cleaner and sustainable alternative to traditional labelling methods.  

How Does Laser Marking Additive Masterbatch Work? 

Laser marking plays a pivotal role in modern plastic manufacturing. It helps in accurate and precise identification, engraving and marking information on various plastic components. The laser beams emit a high-energy pulse that acts on the material to be marked. The laser light is converted to heat energy through the mechanism of laser marking additive, causing the material of the material to melt, foam, colour change and form the desired marking. 

Laser Marking Additive Masterbatch Principle 

Carbonization 

In the initial stage, the laser beam interacts with the surface of the material, generating heat for the resin to become charred and carbonized. The thermal reaction forms a dark marking on the workpiece, typically suited for light colour substrates. 


Foaming 

The laser additive produces heat for a high degree of resin degradation. The heat generated forms bubbles on the surface, producing a light coloured or white marking, typically suited for dark-coloured and black substrates. 


Ablation 

A high-energy laser is used to vapourize the resin and remove a layer of polymer. This reveals a contrasting layer of the base material to produce a highly durable and long-lasting marking. 

Which Types of Plastics Can Be Marked with Laser Marking Additives?

Almost every industry needs marking and identification of parts and components are crucial. Laser marking additives can be used for various plastic resins, including ABS, PC, LDPE, HDPE, & PET. It can also be used for general-purpose plastics and engineering plastics like PVC, PP, PA, PBT, POM, TPU, PET, NYLON, Epoxy resins, rubber and plastic alloys like ABS+PC. 

Advantages of Laser Marking Additive Masterbatch 

Eco-friendly 

The use of laser marking additives eliminates the need for solvents, ink, or any other inorganic substances. With non-contact marking it reduces waste and the need for additional materials for a clean and sustainable identification process. 


Flexibility in Performance 

The additive can be for patterns, numbers, characters, fonts, logos and intricate designs. These laser marks are resistant to abrasion, as well as offering exceptional protection from counterfeiting and environmental elements. 


Efficiency 

As compared to traditional engraving techniques, these additives enable faster speed embossed designs that are challenging to engrave using traditional techniques. This makes it a cost-effective and time-saving marking technique. 


High-precision Permanent Marking 

It is a highly accurate marking technique for high-resolution graphic marking, micro-markings. The marking will not fade or wear out over a period of time, offering great value to product traceability.
