A better understanding of roll forming and its tooling

A roll former may appear to be a tremendously complex machine, with its wide array of stations and high speeds. It’s worth learning about how it works because it can perform a unique function and create identical end products consistently that meet the strictest of specifications. To better understand what the roll forming machine is doing, it’s best to break it down to study each place the metal …

Engineering Angle: Factors affecting sheared edge quality in stamped parts

In the automotive industry, the use of advanced and ultrahigh-strength steels (AHSS/UHSS) continues to expand, as these materials can help reduce vehicle weight while adding strength and improving fuel economy and crashworthiness. The process of stamping parts from sheet metal frequently includes shearing operations such as blanking, piercing, and trimming. In all these processes, shearing …
