Precision Sheet Metal Components in Communication Devices

Today, there are so many ways to communicate that the internal components of our devices are more important than ever. And when it comes to those internal components, especially in the case of modern communication devices, precision sheet metal parts are key. Even though end-users may not see them, they perform necessary and mostly unglamorous tasks that directly affect how well a device works and how long it lasts. Communication devices, much like the human body, need rigorously maintained internal environments. And if the internal environment is going to be rigorously maintained, the components within it need both protection and a somewhat final, fixed state.
Selecting the appropriate material for sheet metal parts is crucial. Conductive materials must be available for the device's electrical functions. The choice becomes more intricate when one considers the need for electromagnetic interference (EMI) shielding. Metals or special coatings are then used, requiring an intricate balance with a device's corrosion resistance—especially for any metal part likely to be used in a harsh environment. Lightweight materials also require special consideration; a device part's strength-to-weight ratio is vital. A sheet metal part must be strong if it is to perform its function at all, yet the right material allows it to be light enough to avoid the not guilty weight problem.
The design of these elements requires complete accuracy, and by this we mean that deviation must be kept within the limits of not being seen or felt and not impacting fit, function, or finish. This sounds simple, but it is something we have to plan for and work at. It requires unfailing attention to detail and a highly consistent assembly process. It is also critically important because the perceived quality of the product is highly influenced by this precision. If it doesn't look and feel right, people will question the value and purpose of the product.
The process that results in precision sheet metal parts involves some of the most advanced tools available for metal cutting, namely the laser and waterjet. These high-energy beam processes allow for not only very smooth edges but also dimensions that are quite precise. When it comes to bending metal, it is CNC machines that do the bending. They are the best in this respect, because they can consistently control the angles and we could say they "bend" the parts in a very nice way. Computer numerically controlled machines carry out all the operations (in addition to cutting and bending, also punching) needed to form a sheet metal part. And here, punching is also done in a precise way, because sometimes, holes (for instance, when a part will be riveted or screwed to another part) must be in a very specific place; otherwise, the assemblies in which sheet metal parts are used may not function correctly.
When communication devices are engineered, the need to shed excess heat is of paramount importance. Sheet metal parts are used extensively as exterior surfaces for heat sinks and heat-path components. Ventilation holes are also employed in the metalwork when feasible, although they obviously come at a price in terms of protection from outside interference—and heat sinks, as we know from the experience of airplane designers, can themselves be a source for taking in chilled water and thereby create a pathway for a potential problem.
Finally, there are quality control measures to ensure that the end product is what it should be. To check dimensions, we use very precise measuring tools and machines—most notably, the coordinate measuring machine. We also use this machine in the prototype department so that we can guarantee what we're asking for in a design is, in the end, what's actually being built. When we ask the prototype department to build something to a certain tolerance, we know they can do it with the assurance we would have making a similar request to the end product assembly line. The reliability and the durability of what we ask for in a prototype test is something we can depend on in the quality of the end product.
