Minerals & Metallurgy
The metal stamping manufacturing process produces strong metal parts and shapes quickly and cleanly. The process uses specialized dies to press sheet metal into the correct shape. Automakers benefit from the use of metal stamping for parts such as fenders and hubcaps because molds can again be used to make parts that are consistent in size and shape to meet tight specifications and tolerances. Some of the key benefits of metal stamping include:
Cost-effective: Once molds are made, manufacturers can produce high-volume auto parts at low cost. Metal stamping technology can handle a wide variety of metals, which gives companies a lot of flexibility without increasing costs. Metal stamping dies themselves are also cost-effective to create and maintain good working condition. Finishing steps such as electroplating to produce parts are also cost-effective.
Material Efficiency: The metal stamping process uses sheet metal to make parts. Sheet metal is efficient and does not add wasted weight or thickness to the part. Sheet metal can be used for a range of parts, including structural elements in an engine or drivetrain, chassis and mechanical components.
Automation: The metal stamping process can be handled entirely by machinery. Not only does this reduce the risk of human error or inconsistency, but it also reduces labor costs and keeps employees safe.
Technology and Technology
The metal stamping process continues to develop and improve with new technologies. Not only has the manufacturing process benefited from increased end-to-end automation, but stamping machinery has also become more advanced. A popular advancement is the use of electromagnetic tools. These devices can better interact with metal plates by using electromagnetic forces to precisely position them. Electromagnetic aids can both make more complex and complex forms and reduce material waste by narrowing the margins between stamps.
There are three popular types of metal stamping machines used for automotive and other industrial parts. They include:
Mechanical press with a mechanical flywheel driven by an electric motor.
Hydraulic press, with a pressurized fluid that controls the pressure and force exerted on the workpiece.
Mechanical servo presses that use only motors and no mechanical flywheels.
All three press types can be used with automated systems such as automatic feeders to increase efficiency and production speed. The automatic feeder feeds rolled or blank sheet metal through the press for fast running.
Metal punches and dies can use many different metals to make different parts. Some of the metals most commonly used in stamping automotive parts include aluminum, copper, and steel. Each metal has unique properties that make it ideal for certain applications.
Aluminum: Manufacturers use aluminum for visible parts and details because of its aesthetic appearance and light weight. Companies can also easily form alloys with aluminum and other metals to create stronger or more durable varieties.
Copper: This metal is corrosion-resistant, malleable, attractive, and affordable. Companies can also choose copper for environmentally conscious customers; the metal is easy to recycle and reuse.
Stainless Steel: This metal is resistant to corrosion and rust because it has at least 11% chromium. Not only does it add durability, but it also has a glossy, attractive finish.eg:prepainted steel coils
Steel and Steel Alloys: Steel alloys come in many different varieties, such as mild steel, high strength steel, and specialty steels that can be used to make a variety of durable components.
