Precision meets innovation: laser welding with compounds from SITRAPLAS
Laser welding of plastics is a widely used method of joining technology today. To ensure a reliable automated process and a high quality welded joint, there are a few things to consider when selecting the material.
SITRAPLAS compounds are specially developed to meet the requirements of modern laser welding. Whether in the automotive industry, medical technology, electronics or other demanding sectors - with SITRAPLAS you can rely on process reliability, precision and quality.
A special solution: laser welding of white opaque SITRALON® (PC) with integrated flame protection.
Opaque white plastics pose a particular challenge in laser welding, as they reflect the laser beam and do not absorb it sufficiently. This can lead to uneven weld seams and therefore lower joint strength. The flame-retardant properties of thermoplastics further exacerbate this problem.
The LW grade of our SITRALON® (PC) guarantees optimum laser absorption, even in combination with flame retardancy. Special additives are used in the formulations to improve laser absorption. This enables you to achieve precise, stable and high-quality weld seams - even with flame-retardant opaque white plastics.
A particularly challenging material pairing was tested for its weldability in a material test conducted by Evosys Laser GmbH.
In the test, the broken weld seam showed a mutual material break-out without any thermal damage. This is a clear indication of the high quality of the weld seam. It is particularly noteworthy that when the weld seam breaks open, the material plate breaks before the seam itself gives way. This underlines the exceptional stability and strength of the joint achieved by laser welding SITRALON® LW grades.
