Non-contact laser welding offers several advantages when it comes to joining one plastic part to another. It works on the principle of partial transmission which lets a laser’s light travel through ...

Figure 1. Various test samples that have been laser welded in an applications lab (a) and a low-density polyethylene fluid container welded with a diode laser system (b). Direct welding of plastics is ...

Lasers have been used to weld together plastic parts for decades, but until recently the technology had one major disadvantage: it could not be used to weld clear polymers. Recently, high-powered ...

Laser welding of plastics is now a convenient and flexible technique that is proving popular for joining automotive parts and medical equipment as well as consumer products. Most people are familiar ...

You want welds that stay consistent, but quality can drift when parts shift, fit-up varies, or different operators take over.

Manufacturers of electronic components with printed-circuit boards (PCBs) have a new method for mounting PCBs to their respective thermoplastic housings or substrates: laser staking. The technology ...

A technology has been developed that significantly shortens the time for the plastic welding process used to seal automotive rear-view cameras. This technology, which introduces lasers into the ...
