If you need a quality roll forming machine, you have many options. However, before make a right decision, it's important to understand the benefits of buying from a reliable supplier like Longway . Here are a few reasons why consider buying your next roll former from here .

Last Month , we finish final testing for a Wall Cladding Panel Forming Machine , which is designed as customer profile for Chile market . Here is the machine details .

Roll forming is a continuous process which converts sheet metal into an engineered shape using consecutive sets of mated rolls, each of which makes only incremental changes in the form. The sum of these small changes in form is a complex profile.

From Wikipedia, the free encyclopediaBending along rollsRoll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section. The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.

Roll forming is a flexible, responsive and cost-effective alternative to extrusion, press braking, and stamping.Well-suited for customized or standard shape production, roll forming is a simple process ideal for even the most complex shapes.

There are several advantages of using roll forming for your projects:

The desired cross section is gradually formed as it passes through the rollers. The material starts as a flat coil or blank and each pair of rolls adds to the shape.

The roll forming process is a metal-forming operation that imparts the desired shape to a material strip in a progressive manner.

A roll former may appear to be a complex machine, with its 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.  

Even design engineers with 20+ years of experience still Google this question. Despite its efficient and industrious nature, roll forming is a niche manufacturing process known to few and understood by even fewer.

Last week, we detailed the advantages of press braking, comparing it to roll forming as a metal fabrication bending process. Although they have little in common, other than the process category, both are important and have many uses. More than anything, choosing one over the other depends mainly on the end product undergoing fabrication. This week, we’ll take a look at closer look at roll forming specifically.

Rolling is a forming process which reduces the cross-sectional area of the incoming metal stock or produces a new cross-section of the material at the exit while improving its mechanical properties through the use of rotating rolls.

The following article is based in part on “Justification for roll forming,” prepared for the FABTECH conference by Brian Rodgers, senior application engineer, Formtek Inc.

AMS Controls’ core business is machine control and production management for roll forming industries. As such, length control is a primary focus, so we wanted to produce a series of articles on issues that can cause length variance– where problems come from, and how to eliminate them. Once we got past encoder issues (which are common across all machine types), we wanted to tackle length control based on machine application – non-stop vs. stopping, servo control vs. non-servo control.

Metal rollforming might not be as simple as you may think; machines can come in a variety of sizes, product outputs, uses, speeds, and more. Before you buy, make sure you’re educated on the background and importance of metal rollforming in today’s industry.

Roll Former offers the most productive and cost-effective roll forming equipment for the metal roofing and architectural sheet metal industries. Since 1978 we have been leading the industry with our innovations and service.

If sheet metal fabrication and aluminum extruding got together and had a baby, you’d get roll forming. Roll forming is like sheet metal fabrication where thin flat sheets of metal are bent into a 3D shape, but in contrast, these bends are formed gradually and continuously so a constant 2D cross-sectional shape comes out the other end like an extrusion. Long strips or coils of flat metal are fed into one end of a roll forming line where it passes through a series of rolling dies and comes out the end in a totally new shape.

Since steel mills producing “long sections” of structural steel–including angles, bars, beams, channels, and tees–manufacture their products through a rolling process, these sections are often referred to as, for example, “rolled beams.” (In part to distinguish them from built-up girders, i.e. beams made by welding three pieces together.)

“Roll forming is a process that uses a set of precisely placed rollers to perform incremental bending to a continuously fed strip of metal. The rollers are mounted in sets on a consecutive stand with each roller completing one small step of the process.
