Cold forged parts are a popular choice for manufacturers that need to produce products that can withstand the harsh conditions of the automotive industry. They are available in a wide variety of materials and can be produced quickly and efficiently at high production rates.
Cold forging is a process that enables metals to be formed into shapes without the use of heat treatment. This process is widely used for a number of reasons, including its ability to create close dimensional tolerances and perfect surface finishes.
The advantages of cold forging are that it can be used to make a wide variety of shapes, it can be done at room temperature, and it does not produce shavings like hot forging. These features help to increase productivity and reduce the cost of production.
A cold forged part is created by placing a piece of metal between a die and a punch. Then, it is shaped and molded into the desired shape by using pressure to cause it to conform to the die.
Another advantage of the cold forging process is that it can be used to form a variety of different materials, including aluminum and stainless steel. This allows for more flexibility when it comes to designing components and can be used to create products that require close dimensional tolerances or high strength.
This process can also be used to produce a wide variety of shapes and sizes, including holes, chamfers, pins, elliptical fins and steps. This process allows for the creation of intricate contours and shapes that would otherwise be difficult or costly to do through other processes.
Depending on the finished product, this process can be used to make everything from gears to rivets and many other types of hardware. In addition to enhancing the strength of the product, it can also help to reduce the cost and make the parts more durable.
Cold forging can also be used to produce a number of different sizes and shapes, including larger pieces that would not be possible through other processes. This is particularly useful for creating axles and leaf springs that are used in automotive applications, as well as for other mechanical devices that have a range of complex features.
These types of parts can be manufactured on both hydraulic and mechanical presses, but are more commonly made on mechanical press machines. They should be lubricated before and after being formed to prevent stick-ups that can occur during the process.
A common way to do this is with a zinc phosphate or polymer coating. This type of coating can be very effective at preventing errors and keeping the workpiece from sticking to the die, extending the life of the tool.
Other ways to lubricate the tools that are used during this process include using calcium aluminate, aluminum fluoride or phosphate coatings. These can be applied to the dies and the workpiece before they are forged to ensure a long life of both items. This can be a great way to save money on the manufacturing process and prevent expensive mistakes.
