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 ...

Introduction The automotive market is continuously evolving, as cars are required to be light and highly fuel-efficient, as ...

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 ...

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 ...

Industrial lasers are used to process engineering plastics across many markets. Some examples of the common processes are shown in Figure 1, including laser marking, cutting, and welding.

In this video, we create a recycled plastic box using plastic welding techniques, eliminating the need for screws or fixings.

The last two decades have seen substantial improvements in ultrasonic plastic-welding machines. Bench-top models feature proportional-valve controls, linear encoders, line-voltage regulation, internal ...
