This cold forming technique avoids stresses associated with hot forming or machine presses.<\/p>\n\n\n\n<p>[Diagram showing custom roll forming working stages from unwinding coil to finished profile]<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Coil\/sheet feeding<\/li>\n\n\n\n<li>Accumulation\/degating for continuous high speed forming<\/li>\n\n\n\n<li>Initial shaping through pre-break rolls<\/li>\n\n\n\n<li>Gradual incremental bending at multiple stands via contoured rolls<\/li>\n\n\n\n<li>Additional integrated secondary processes like punching or notching<\/li>\n\n\n\n<li>Part cutting to length at exit end<\/li>\n\n\n\n<li>Formed profile collections and packaging<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Design and Customization Capabilities<\/h3>\n\n\n\n<p>Roll forming imparts durability with uniform profiles tolerant to high loads. Custom roll formers produce parts suited to any volume through rapid design of application-specific tooling matched to end use size specs without dies required with stamping.<\/p>\n\n\n\n<p>Forming analysis tools like CAD, FEA optimize cross-sectional design. Flexible tooling design enables cost-effective customization in dimensions, hole patterns, notches and overall part functional geometry. Common feature additions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Custom widths and diameters<\/li>\n\n\n\n<li>Lengthwise curling of edges or reinforcing ribs<\/li>\n\n\n\n<li>Perforations and louvers for weight reduction<\/li>\n\n\n\n<li>Holes, slots, notches and tabs for joining applications<\/li>\n\n\n\n<li>Embossing and text for branding<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Materials Handled<\/h3>\n\n\n\n<p>Custom roll formers process low to high strength metals with excellent surface finishes free of flaws, tool marks or warping associated with alternative techniques. Materials include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mild steel<\/li>\n\n\n\n<li>High strength and alloy steel<\/li>\n\n\n\n<li>Stainless steel<\/li>\n\n\n\n<li>Aluminum<\/li>\n\n\n\n<li>Specialty alloys<\/li>\n\n\n\n<li>Pre-painted\/coated stock<\/li>\n<\/ul>\n\n\n\n<p>Materials under 0.15 in (3.81 mm) thickness can be formed without splitting or tearing.
