...limitations. With respect to the nature of beam delivery, there is little difference between the. techniques used for metal and plastic welding. The essential difference in the plastic. welding approach is the through transmission IR concept. Figure 1: The laser transmission welding principle...

: the ability to use an extrusion to provide variable length and width and the use of injection moulded corner pieces to provide the necessary jointing. The requirements for light weight and easy assembly rule out the use of welding and the assembly is built up using the clip-in corner pieces which give...

...turnaround. Product platforms also need to be highly configurable. These qualities can be fully achieved with modern sheet-metal fabrication methods. When these techniques are used in conjunction with laser welding, the results can exceed the functional criteria demanded by most case and tray...

...fasteners such as machine screws or sheet metal screws. However, in some cases welded flanges are desired. Spot welding would be used in cases. where disassembly is not required. Fully seam welded edges may also be a requirement,. especially if the application requires a more tightly sealed enclosure...

...created unacceptable conditions. To address these issues, the next step in development of vision sensors for assembly monitoring provided sensors for in-process monitoring. Most automotive sheet metal assembly operations involve spot welding, an environment with weld splatter, smoke, high...

sheet shows deliberate non-uniform or “profile heating” of the sheet. Cooler sections at the corners are intended to control drawdown in those locations. Ability to monitor and modify the surface temperature of a heated sheet is critical to making high-quality thermoformed parts. In most cases...

Metals and Plastics. A designer and manufacturer offers resistance welding and reflow soldering power supplies, heads, monitors, and accessories for both large-scale and fine-spot applications that require precision metal joining. Unitek Miyachi Corp. (Monrovia, CA) has introduced a diode-pumped...

...disassembly. Welding further causes undesirable fumes and burnouts and often needs complicated electrodes and pilots that can stall production. Some types of conventional mechanical fasteners have drawbacks as well. For example, sheet-metal screws may lack adequate holding power and aren't always...

...hours. Potential Drawbacks. Is TPE the right choice for every application? Of course not! There are issues with bendability in corners. There are also problems with form-curing TPE profiles, and excessive flash when welding frames.  Because of their higher material costs compared to other rubbers...

...aluminum, steel, or copper beryllium, and any metal that conducts electricity will work. The nest usually has a buffer board or sheet attached in the seal area to minimize the heat-sinking effect of the metal nest and provide an insulated landing for any tear-seal tool edge. The reason for most tools...
