Die casting is an efficient and effective way to produce the parts needed in large quantities for various industries. It is the most commonly used manufacturing technique, as it is capable of producing the required product quickly and accurately. Die casting works in conjunction with plastic molding and other processes, including forging, machining, and electroplating, to create final products.
The basic principle of the die casting process is that a liquid metal is introduced into a die, and a plunger forces the liquid metal out, causing it to fill the mold. This is done repeatedly, creating layers of metal.
The mold used must be constructed of special alloys that are resistant to the heat die casting parts manufacturers of the molten metal. For this reason, molds are fabricated from refractory materials, and the part must be removed after solidification of the molten metal.
The most common metal used in die casting is aluminum, which can be cast in a wide range of shapes and is easy to clean. Aluminum is also readily available, inexpensive, lightweight, and resistant to corrosion. The die casting process begins with the preparation of a master tool. The tool consists of a pattern, which is a negative replica of the shape to be cast. The master tool is first formed using a wax or wood model, then used to make a positive replica of the mold.
