How does Hot Metal Stamping Work for the Automotive Industry?

Posted by

The manufacturing process of metal stamping cleanly creates robust metal forms and parts. It is the process that the automotive component manufacturer uses, and the process uses the specialized dies that press the metal sheets into their exact form. 

The auto manufacturers benefit a lot through metal stamping for the parts like the hubcaps and fenders since the dies are use for creating consistently shaped and sized parts meeting the strict tolerances and specifications.

How does the Automotive Component Manufacturer Use Hot Stamping?

Hot stamping is press hardening or hot forming, referring to the processes of forming metal while it is super-hot and is rapidly cooled down. The press-hardened metal is heated over 1700 degrees F in the initial stage of the press line.

The material is transferred instantly onto the press, and part forms while the material is already hot. Therefore, the material is cooled quickly in the die by the stamping supplier in India. The process alters low-tensile-strength metal to highly high-strength steel.

Why Use the Hot Stamp Process?

Hot stamping has proved to be an extremely effective process in production for the automotive industry with the following benefits:

Increased Tensile Strength

The relatively complex parts are formed in a single step that yields the shaped part with a strong amount of times stronger than the regular steel part.

Complex Components

Hot stamping forms the complex parts in a single stroke. Therefore, the multi-component assemblies are redesigne and formed in one part eliminating a few additional joining processes such as welding.

No Spring Back

When the automotive component manufacturer uses the hot stamping method, it relieves warping and spring back issues.

Lighter Weight

Some parts are both lightweight and higher in strength levels as it results in lighter and fuel-efficient vehicles and becomes more impact-resistant.

High Production Speed

The technology is extremely suitable for higher speed in terms of production.


After the dies are made, the stamping supplier in India creates higher volumes of runs of automotive parts at lower costs. Metal stamping techniques mainly handle a variety of metals allowing the companies a huge degree of flexibility without any extra costs. The dies for metal stamping are cost-effective and work properly. The last steps of the parts that are produce involve plating are cost-effective.

Material Efficiency

The process of metal stamping uses sheet metal for creating the parts. Sheet metal does not add any wasteful heft or thickness to the part as it is efficient. Sheet metal is use for an array of parts, including the structural elements, chassis, and mechanical components in the transmission or engine system.


The processes of metal stamping are handle completely through machinery. It reduces a lot of risk for human error and inconsistency as it lowers labour costs and retains safety for employees.

Techniques and Technologies

The metal stamping processes continue developing and improving with new technologies. The manufacturing process benefits through the increased end-to-end automation; however, the stamping machinery is becoming much more advanced. One of the most popular advancements uses electromagnetic tools.

Types of Metal Stamping Presses

The automotive and other industrial parts involve three popular kinds of metal stamping presses, such as:

  • Mechanical presses having mechanical flywheels involving motor
  • Hydraulic presses have pressurized fluids controlling the pressure and application of force on workpieces.
  • The mechanical servo presses use only motors and no kind of mechanical flywheels.

These three kinds of press work with the automated system, such as the automatic feeders, to increase production speed and efficiency. The automatic feeders send blank sheets or coiled metal through the presses to create a fast run.

The hot metal stamping is well-suited for forming elements that are lightweight and quite strong. The technology is extremely suitable for various safety-critical structural parts, including bumper beams and door reinforcements for the automotive industry. 

There are indicators use by the stamping supplier in India that are use for continuing growth at increasing rates. The sheet metal is use across various industries, including aerospace, auto, telecommunications, electronics, etc. 

Furthermore, the prices for the metals have reduced significantly, offering more affordable conditions for using metal stamping. Finally, many companies are envisioning the benefits of using metal stamping for clients.
