GRAFE Masterbatches for laser marking

Laser markings on plastic parts are resistant to chemicals and abrasion, and result in a permanent and clear inscription. The plastics experts at GRAFE provide their customers with masterbatches for plastics which can be written on with lasers. In pretests using their own in-house laser marker, they are able to determine the ideal settings for writing on the plastic. GRAFE supports its customers by providing the perfect laser marking solution with a comprehensive range of services.


"Laser marking is a highly efficient process in the design of plastic products and has become a real alternative to conventional printing methods over the past years," says Lars Tonnecker, Head of Sales at GRAFE. "It is quick and economical, and it results in a durable, very clean, precise and well-defined marking without having to pre-treat the parts."


Laser marking can be implemented in three types of marking colors: light, dark and colored marking. The end-result is determined by the process, the polymer and the admixtures that are used, such as pigments and other additives. These additives are necessary in the laser marking process to guarantee the required standards of contrast, definition and marking speed. Tonnecker continues: "Depending on the desired application, we develop the ideal formula for the masterbatches. These are then tested in-house for their suitability for writing on using our own laser marker from the company FOBA. This means that our customers receive a fully tested plastic product along with all the parameters necessary for marking the part later.”


One thing is sure: Whether it be for barcodes, type plates or writing on cables and parts for the automotive industry, – the laser marking of plastics has grown in importance over the past years. Due to its high flexibility for changing layouts and other technical advantages, it is quickly replacing the conventional printing of plastic parts. The technology is suitable for application in all areas where components are marked without using chemicals and are resistant to abrasion.
