Pressure Die Casting Aluminum Audio Speaker Parts vs Extrusions. Audio Speakers and other sound-related components don’t live without going through maintenance and parts replacement. Eventually, after months or years of use, parts need to be replaced with newer ones to continue its lifespan. Many of today’s consumers would turn to die casting to be able to get parts instead of buying a new component every time a part of the system starts malfunctioning, and one of the processes used to create speaker parts is extrusions. Extrusion, if you look it up over the net, is basically a process used to create objects (in this case, parts) of a fixed cross-sectional body. The top advantages of using extrusions are being able to create complex cross-sections and being able to work with materials that are normally brittle and that can easily break.

But because of the limitations involved in extrusions when it comes to shaping and the time spent to produce the parts, manufacturers are now turning to pressure die casting using aluminum as the main alloy. As compared to extrusions, die casting with aluminum makes production faster, allows more net shape, and all the features of the part, from top to bottom, side to side, can be done in one operation alone.

Examples of Aluminum Heat Sinks Die Castings. Heat sinks are devices used to remove heat emitted from parts of electronic applications or appliances. Examples of these are your mobile devices, computers that run 24/7, audio amplifiers, and the like. Though heat sinks have already been made and used prior to the development of aluminum heatsinks, they didn’t last long plus they were more expensive and had limitations in terms of thermal conductivity. When manufacturers of heat sinks started producing them but made with aluminum, people discovered the benefits they got from them such as the increase in durability, cost efficiency, and better thermal conductivity.

Another significant benefit when using aluminum heat sink die castings is the ability to conduct electricity. This means that you don’t have to keep adding copper plating, the heat sinks are easily electrically grounded, and you can prevent further danger when dealing with large amounts of electricity.

There are many examples of aluminum heat sinks that are being used by people everyday. These people normally use electronic applications that emit large amounts of heat from their interior parts and components, so it is only safe to use these heat sinks to prevent breakdowns or malfunctions. Examples of these include CPU heat sinks, refrigeration, cooling electronic devices, and motherboard heat sinks. You will also find aluminum die casting heat sinks being used to cool down PCs, cell phones, and other equipment.

Pressure Die Casting Aluminum Speaker Parts vs Gravity Casting. Pressure die casting is a manufacturing process used to create aluminum brackets, parts, chassis and more. These metal parts can be seen almost anywhere and everywhere, making them integral in our day to day lives. Pressure die casting initially melts the aluminum metal. The molten metal is then injected into a mold under great pressure. Afterwards, it is set aside to cool for a while. When the Mold is opened, it reveals the finished die casting. Because of this fast and easy process, thousands of parts can be made every day.

Gravity casting uses the similar manner as sand casting. It uses the force of gravity rather than high pressure to fill the mold with the molten aluminum metal. Gravity casting is most fitting for mass production and full mechanized casting. One advantage over gravity casting is that they usually give a better surface finish and mechanical properties, due to its slower cooling rates compared to pressure die casting.

Compared to gravity casting, pressure die casting requires less machining. Die castings can cast holes depending on how and where you want it. Die castings give closer and more accurate dimensions, plus it can be produced at a larger scale, with less labor costs per casting.
