Automotive Roll Forming

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.
