Fabricated High Strength Steel for Automobiles
The rising demand for fabricated steel parts by the automotive industry is quite understandable. First, steel costs about one-fifth of the price of aluminium when bought in bulk as required by a car manufacturer. Second, the currently available car shapes demand thinner sheet steel which is not only lighter but also cheaper. Lighter steel parts allows for lighter cars which in turn results into greater fuel efficiency. There is yet another reason for greater usage of advanced high strength steel or fabricated high strength low alloy steel in the automotive industry. Most companies dealing in iron and steel industry have substantial experience when it comes to shaping and forming steel compared to the other materials to make vehicle bodies.
Advanced high strength steel or high strength low alloy steel can be effectively fabricated for producing parts used in the automotive industry with the help of roll forming machines. Roll forming is a continuous steel sheet bending process wherein a long strip of steel is made to undergo consecutive sets of rolls or stands, each performing an incremental part of the bend, until the desired cross section shape or profile is achieved. In most cases, advanced high-strength steel types are bent to produce steel with suitable mechanical properties required in the automotive industry. The process used is called the hydro forming process where high water pressure is used to mould the steel over the die. There are different types of roll forming machines available. The final choice depends on the steel specifications of the automobile manufacturer.

Roll Forming Automotive Structural Parts
Manufacturing quality auto parts is not that difficult as it was before the advent of metal roll forming machines. Earlier the auto parts manufacturers used to stamp or brake press for making chassis, bumpers, cross supports, door window runners and critical crash assembly systems.
The auto industry has been in dire need of quality parts as car making companies compete to launch new models in quick succession. Stamping method was labor intensive and it could not produce quality auto parts in huge numbers. But roll forming machines have solved the puzzle. Let’s see what one can do with metal rolling & forming.
A metal forming equipment helps reduce the number of defective auto parts produced. Metal forming rolls also help increase the volume by reducing the per part costs. Another big advantage of roll corporation is repeatable part tolerances. Today, roll form equipment comes with flying technology. With the help of this technique, a metal roll forming equipment can cut profiles on-the-fly. Leading auto parts manufacturers use special software in metal roll former for quality products. Known as Finite Element Analysis, the software helps test drive the mill before producing it.
Metal forming roll has also helped the auto industry battle skyrocketing steel prices. Metal roll forming machine was invented at a time when auto parts manufacturers were asked by the car making companies to make affordable parts. Since metal rolling & forming consumes all the steel and produce little or no waste, it provides the tailor-made solution to the auto parts manufacturers.
