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 Tooling brings life to new automotive platforms
Roll forming machines have changed the way auto parts manufacturers make bumpers, chassis components, cross supports, door window runners and critical crash sub-assembly systems. Earlier the auto parts manufacturers use to brake press or stamp parts. It was a time consuming and labor intensive method. But after the advent of roll forming machines, it has become much easier for auto parts manufacturers to make quality auto parts. Today, the auto industry is growing at a rapid pace. There are many companies that make cars and trucks. They need quality parts and it is not possible for auto parts manufacturers to make parts in large quantity with brake pressing. So they are using roll forming machines.
Roll tooling or machine tooling is the most important part of roll forming machine. Metal tooling allows the sheet metal to be bent in to various shapes and sizes as the metal moves through the press tooling. By adding rafted or cassettes on a roll former, a manufacturer can reduce brake tooling change over time. Rafting helps in reducing bend tooling time to that point where running shorter runs of multiple profiles has highly profitable per part costs. This is due to the right alignment of tools roll in an automotive roll forming machine. A roll former with well aligned roll punch manufactures quality auto parts with minimal re-adjustment.
Roll forming machine has also helped auto industry in battling rising steel prices. With roll formers, auto parts manufacturers produce quality auto parts with no or little waste.
