Technical Information about Die Casting
Die Casting, A Description of the Die Casting Process- Die casting is a manufacturing process in which molten metal is injected, under considerable pressure, into a hardened steel die or also called die casting mold. Dies are often water-cooled. The die is then opened, and the die casting parts are ejected (many times thousands of die casting parts each day, sometimes only a few hundred die casting parts). Once the die casting tooling is paid for, die casting parts are a very inexpensive aluminum part manufacturing process.
Aluminium die casts are light in weight. In contrast to other die cast materials, aluminium can resist extremely high operating temperatures. Their strength, flexural rigidity and resistance to corrosion guarantee excellent heat dissipation. Due to its excellent shielding properties and light weight, aluminium is the preferred material for electronic housings.
Heat sinks remove heat from parts and components in electronic applications. Aluminum heatsinks are designed in a way that requires less machining than other manufacturing processes. The cooling fins can be manufactured at the same time as the mounting holes. Heatsink parts are made with all features necessary for cooling electronic components and to mount the heat sinks on the printed circuit board (PC board). Aluminum heat sinks have a high dimensional stability. Heat sink production begins as soon as the tooling is produced.. Heatsinks look good as raw parts or can be anodized or powdercoated.
Heatsink parts or heat sinks made in aluminum draw heat from PC boards and have a thermal conductivity CGS of 0.23. The electrical conductivity of aluminum die cast heat sink parts is 27 percent of copper standard. Aluminum heat sinks are also very light, having a specific gravity of about 0.10 pounds per cubic inch. Some aluminum heat sinks have external threads cast into place. The maximum threads per inch die cast into place is 24 TPI.
Aluminum heat sink parts have another advantage. They are electrically conductive. This benefits the manufacturers in three ways:
Aluminum heatsink parts do not need added cost plating in copper.
Because the parts are electrically conductive, they can easily be electrically grounded.
Aluminum Heatsink parts are used for RF and EMI shielding..
