Almost all plastic can be marked using a laser – whether it’s polyamide, ABS or polycarbonate. Enjoy the benefits of JustLaser laser machines: an exact, permanent marking without damaging the surface. Marking plastic with a laser is contactless, the results are permanent, abrasion-resistant and resistant to acids, alkaline solutions, solvents and (hot) oils. Regardless of whether you’re making black or white marks – a laser marker from JustLaser with high peak performance and short pulse duration provides optimal results, even for challenging designs.
Experience has shown that marking plastic with a laser marker is an advantageous method with a number of possible applications. A large number of plastics are suitable for laser marking:
As almost any plastic can be processed using a laser, the range of applications for laser marking plastic is large. The marking method is based on the material and the desired result. Admixtures (e.g. flame retardants, additives, etc.) and pigments in the product react to laser marking in different ways. So, you work with the foaming, carbonising or recolouring techniques. It is recommended that you carry out a test before the production run to check that the quality and processing time can be reproduced. The following components are frequently marked using a laser:
When marking plastic with a laser, various methods can be used thar are based on the coupling of laser light. The energy has the effect of carbonising or foaming a polymer. This results in the desired change of colour. The following variants are used in practice:
It is possible to mark individual pieces or hundreds of parts simultaneously when marking plastic with a laser. The laser markers from JustLaser are based on ytterbium fibre laser technology (table value: 1,062.3 nm), causing a temperature increase and subsequent reactions of the chemicals in the plastic. The resultant marking will be light or dark – in either case, it will also be permanent. Predefined colours can be created when using additives or laminates. Very small fonts (up to 2.5 pt.) which can only be read using a microscope can also be produced. It is also possible to mark very large working areas without any issues.
You can use your usual software to create your desired marking (at a resolution of up to 1,200 dpi). The laser technology from JustLaser can be integrated with almost any Windows-based software, including AutoCAD, Adobe, CorelDRAW and Bartender. You can connect the laser to your computer quickly and easily via USB or Ethernet interface.
It is more economically efficient for many businesses to buy their own laser than to outsource component marking to external companies. The relatively low cost of a laser marker from JustLaser and its versatile range of potential uses make it a sensible investment for businesses of any size.
A big benefit of using a laser to mark plastic is that even the smallest components and details on difficult-to-reach places can be marked quickly and easily. Contactless processing provides perfect, highly-resilient results. The plastic component doesn’t need to be clamped or secured for this process, guaranteeing process safety. The process leaves component surfaces (colour change) completely undamaged. It is not necessary to carry out any special pre-treatment or post-treatment.
The results are high-contrast and can be read easily, even with the smallest line widths. They are heat, solvent and acid-resistant, and are permanently abrasion-resistant. In terms of optimal quality assurance, this guarantees long-term traceability for components and products.
A large number of different plastics are suitable for laser marking or cutting. There are practically no limits to design: Dynamic content from ERP systems, logos, serial numbers, data matrix codes, barcodes, photos and much more can be produced on plastics using a laser. The marking is quick and efficient – it isn’t necessary to change tools or retool for different inscriptions.
In comparison to alternative processes, marking plastic with a laser is considered to be an extremely cost-effective variant. There are no maintenance costs (no tool wear) or costs for consumable materials (chemicals, inks, etc.). The process is significantly quicker in day-to-day work than mechanical processes, for example.
Laser markers from JustLaser are characterised by a range of benefits. The flexible technology is suitable for a broad range of materials. As this method is contactless, the material remains unstressed mechanically. There are also no tool costs or expensive maintenance works.
At JustLaser, you can also benefit from low investment costs and set-up costs and purchase a high-quality product that will win you over through its high throughput speed and precision!
