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 ...

If your project requires joining two pieces of plastic and need a stronger connection than you'd get with glue you can weld two pieces of plastic together by using a rotary tool to spin a plastic rod.

Even though 3D printers can fabricate complex shapes that would be nearly impossible to mill, they are not well suited to designs requiring bridging or with large empty spaces. To overcome this, ...

Select the right welding system when joining rotationally molded parts. It's often to a designer's advantage to make a rotationally or rotomolded part as simple as possible, then customize it with ...

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 ...

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.

Last time we talked about a video that purported to do plastic welding, we mentioned that the process wasn’t really plastic welding as we understood it. Judging by the comments, many people agreed, ...

The automotive industry is experiencing an essential transformation because manufacturers require fuel-efficient vehicles combined with lower emissions along with safer transportation systems. The ...
