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 ...

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 ...

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.

Plastic welding systems maker Dukane Corp. is expanding its equipment portfolio with the acquisition of Blackhawk Technology Group LLC, a contract manufacturer of laser plastic welding services and ...

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 penetration welding operates contact-free and enables direct process control. The question on how plastic parts can be bonded permanently in the best possible way has been occupying the minds of ...

The longevity of plastic is both a blessing and a curse. On the one hand, it’s extremely durable, inexpensive, and easy to work with, but it also doesn’t biodegrade and lasts indefinitely in the ...

A laser blast produces miniature diamonds from plain-old plastic. That’s right, the same kind used in soda bottles. When squeezed to about a million times Earth’s atmospheric pressure and heated to ...

At MD&M West, Emerson demoed its Branson laser plastic welding portfolio, including a Galvo welder that uses photons to weld plastics without vibration and contamination. As Machine Design’s content ...
