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 ...

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

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.

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 ...

Device makers are taking increased interest in product designs and assembly that support closed-loop recycling. A Branson plastic welding process can safely and nondestructively “unweld” plastics used ...

Making vehicle structures out of a combination of metals and plastics could make them dramatically lighter, stronger, safer and more environmentally friendly than the all-steel or all-aluminum ...

Unlike composites made with a thermoset matrix, thermoplastic composites (TPCs) require neither complex chemical reactions nor lengthy curing processes. Thermoplastic prepregs require no refrigeration ...

Owning a workshop requires some knowledge about the basics of welding. It is also important to familiarize yourself with the different types of welding, and where it should be applied. Most workshops ...
