LASER WELDING

SAME PERFORMANCE WITH IMPROVED LASER TRANSPARENCY

PROMYDE’s new polyamides have been developed based on a change in morphology, allowing a four-fold improvement in direct laser transmission and improving overall transmission by up to 50%.

This new solution is a milestone, as laser transparency for polyamide 6 has not been achieved before, and mechanical properties are comparable to those of standard unreinforced PA6.

Laser welding consists of joining a transparent part by means of laser beams, melting the underlying half of the component that absorbs the laser beams. Thus, laser welding is the fusion of a laser-transparent material with a laser-absorbing material.

With the improved laser transparency offered by Promyde, it is now possible to weld thicker thicknesses with an unbeatable surface finish and weld strength. In this way, applications that previously required other joining methods can now be laser welded.

Therefore, new Promyde laser welding polyamide not only opens up completely new possibilities, but also makes a significant contribution to the efficiency of the part welding process.

LASER WELDING: CRYSTALLINITY AND MORPHOLOGY AS KEY FACTORS

Laser welding of partially crystalline thermoplastics is more complex than that of amorphous plastics due to the scattering of the laser beam in the spherulites. This problem was recurrent in all partially crystalline plastics, especially with polyamide 6.

Thanks to the Promyde laser welding innovation, it is now possible to create a Polyamide 6 structure with improved optical and mechanical properties.

DIRECT TRANSMITTANCE: TRUE LASER TRANSPARENCY

In addition to increasing laser transparency, Promyde laser welding polyamides improve the quality of the transmitted laser beam, i.e. direct transmittance.

In the case of Promyde laser welded polyamides, the direct transmission reaches 96% of the total transmission. This is directly related to reduced laser beam broadening and therefore to exceptional weld quality.

LASER WELDING: CRYSTALLINITY AND MORPHOLOGY AS KEY FACTORS

Advantages of laser welding are important for small parts where flexible geometric design and clean operations are needed. Thus, Promyde grades for laser welding:

  • They allow materials to be joined with high precision without damage and without structural changes. Laser welding avoids the need for adhesives and/or other bonding materials.
  • It is especially interesting for electronic devices, automotive control units or assemblies with sensors.
