Emergence of High Strength Steel Forming Machines
The demand for lighter vehicles following the 1970 fuel crisis led to the growing need for high strength steel, specially fabricated for the automotive industry. This called for the development of specialized pressing tools that can fabricate advanced high strength low alloy steel to produce different parts used in manufacturing cars, trucks and buses.
Today, we have special steel roll forming machines that continuously bend strips of steel or steel sheet into the desired cross sectional shape. This results in the production of automobile body panels like high strength steel plates conforming to steel specifications of the manufacturer. The roll forming machines used for fabricating advanced high strength low alloy steel need to feature harder die tools, also known as roller dies, as the press needs to be stronger and more accurate. A quality metal roll forming machine can produce high strength low alloy steel parts in large quantities or with long lengths and thus perfect for use in the automotive industry. It can fabricate rigid and high strength automotive parts from steel as heavy as 6 gauge. It can also be used to produce metal building components, studs, supports, angles, as well as roll formed channels like C-channels, U-channels, and hat channels.
All leading automobile manufacturers have their own steel specifications and so get the roll forming machine custom built. They usually need steel fabricated parts that have greater strength-to-weight ratio which can not be obtained through other methods such as forging.

Roll Forming Machines for Automobile Industry
Automobile industry has changed the way it used to produce structural body parts and auto rack parts required for producing cars and trucks. The rising steel prices may be the cause to this change but a shift in technology has been beneficial in many terms. Here, we will evaluate the new technique used in making body structural parts.
The process of making a car starts with the production of auto structural body parts. To produce body structural parts in large amount, auto parts manufacturers use metal stamping. The metal stamping is a labor intensive process. In addition, a high volume of steel goes into waste without being used in the manufacturing process. To battle steel prices, auto parts manufacturers need a technology, which can make bumper, D-Pillar, C-Pillar, D-post, window slide, longitudinal stiffner, roof cross member and crossmembers with no scrap, out of costly high-strength steel. They found all these characteristics in the roll forming machines.
Today's roll forming machines not only produce little scrap but also reduce the number of defective parts considerably. In this way a roll forming machine consumes maximum steel and makes high-strength body structural parts for car manufacturing companies. In addition, latest roll forming machines are labor intensive. It means that you can make as many quality parts as you want without putting in much labor.
Now roll forming machines use flying technology for cutting the profiles ‘on-the-fly’. You can also incorporate ‘rafted’ or ‘cassettes’ on a roll forming machine to reduce roll tooling change over times dramatically.
