When an automobile user thinks of die cast aluminum, they tend to think of the alloy wheels in a motorbike first. Unlike the bulky die cast aluminum, the alloy wheels have thin separations and are lightweight in general. In fact, the alloy wheels can be as light as the magnesium wheels, and still give balanced finish and higher tensile strength.
Thick Wall Aluminum Die Casting Requires Time
Engineers tend to spend more time casting aluminum, especially on the heavier parts of an automotive. The thick separations can range up to 15 to 20 millimeters at the heaviest. The molten metal is filled into a die until the aluminum cools down and solidifies gradually.
Aluminum has a high freezing and melting point, making the process straightforward for the die casters, but it also makes the die cast process somewhat time-consuming.
Thin Wall Aluminum Die Casting Requires Skill
The time taken to solidify aluminum from a liquid state is less for thin automobile components. Hence, to create one-millimeter thin component, the filling needs to be done every 30 milliseconds or so.
The skill level and engineering precision can determine the success rate in die casting and so does the tool at hand. In fact, the modern day die cast tools give better control in bending, drop-in positioning, and 3D designing. Even the tensile strength is gauged through force using advanced tools.
Plus Points of Aluminum versus Steel Alloy
The benefits of die cast aluminum go to the ancillary industries in the automobile segment. Thin wall die casting creates lightweight automobile component such as the alloy wheels to name one. If you measure the steel wheel and standard alloy wheel of an automobile, you can see a difference in the finish.
Aluminum could hold up the high temperature, making the alloy wheels noticeably distinct. Moreover, the casted alloy wheels are trendy, corrosion-free, and offer high tensile strength.
Segments that Rely on Ancillary Industry
To cast alloy wheels with a thin wall, the industry finds the state-of-the-art die cast engineers. Further, die casters have found a way of late to cast standard aluminum using process and technology. Traditionally, it is an ancillary company using quality controls, avant-garde molding tools, and machinery that supports the automobile segment.
The automobile is one segment that relies on the die casters expertise, another one is the telecommunications segment.
