Steel coil slitting line often works for big coil material , whole line can cut big coils into small coils with rewinder function . Longway Roll Forming Machine ship whole slitting line today .

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.

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.

For decades, roll forming equipment on shop floors across the continent have formed various conventional steels with low carbon content, high ductility, yield strengths between 36 and 50 KSI, and tensile strengths up to 80 KSI. In recent years, roll formers have needed to make more parts from high-strength materials: stainless steels with tensile strengths up to 95 KSI or high-strength/low-alloy (HSLA) material with tensile strengths up to 110 KSI.

High-strength steels have become increasingly popular for use in the automotive industry mainly because of their very high strength-to-weight ratios. However, formability in these same materials remains a problem; the yield strength is very high in these metals, which means the springback is very high. This makes roll forming parts a challenge. However, the efficiency of roll forming makes it an ideal process for producing certain parts compared to hot stamping. If you intend to roll form high-strength steels, it’s important to understand how you have to adjust your equipment to get the best results. You also have to consider the steel you are purchasing and how that is affecting the process.

The global roll forming machines market size is poised to reach USD 121.56 million by 2023, according to a new report by Technavio, progressing at a CAGR of more than 3% during the forecast period. This means that choosing a suitable roll forming machine manufacturer is crucial for your business development. But how do you select the best roll forming machine from the many manufacturers available? In this article, we will introduce you to the key factors to consider when choosing a roll forming machine manufacturer, based on the guidelines of the International Roll Forming Standards Committee.

Tooling costs in manufacturing are already a sore spot for many purchasers, but some think roll form tooling is cost-prohibitive altogether. The up-front price tag tends to blind them to literal down-the-line savings.That’s right -- if your project fits, a roll form manufacturer can actually optimize your spending and get your parts out the door sooner and for less money per part.

While there is no catch-all roll forming solution for every business, there are some elements of the roll forming process that ring true across operations. Regardless of your size, your industry, and even your end product, roll forming machinery is designed to add efficiency, quality, and ultimately profits to your metal forming processes. The requirements necessary to maintain and operate a roll forming system can be loosely defined depending on your shop's specific needs. In this post, we'll discuss some of the variables that determine roll forming line operation and setup across metal forming industries.

As a business owner, you have to make decisions everyday that have an impact on the operations and profit margin of your business. When regularly working with metal roofing and siding panels, some contractors choose to offer on site roll forming for its many benefits as opposed to using factory made panels.At Western States Metal Roofing, not only do we manufacture metal panels but we also offer an on-site roll forming service to roofing professionals in the state of Arizona. However, if you are located outside our service area or use roll forming often, having access to your own roll forming equipment might be a better fit for you.  Here are the benefits of a portable roll former: It’s less expensive to buy metal coil and roll form the panelsLess shipping damagePanel lengths are determined at the jobsite which can lead to less manufacturing mistakes. Less packaging and freight costIf you’ve decided that your roof business needs a portable roll former, the next decision is which roll former do you get? In this article, we will discuss the top 5 portable roll forming machine manufacturers. In addition, we go over the pros and cons of leasing and buying so you can decide which option is better for your business.

Whether you’re a standing seam metal roofing contractor or regional panel supplier/manufacturer — it’s critical to buy the right roof panel rollforming machine from a manufacturer that you trust.We often hear from industry professionals about the overwhelming number of options of machine manufacturers, configurations, and types. Plus, many contractors want to fully weigh all of their options and make sure they’re getting the best machine for their business, especially with something so integral to a metal roofing installer or manufacturer’s productivity.Sheffield Metals is an industry leader in the distribution of coated and bare metal products used to rollform standing seam metal roofing and wall panels. While we don’t manufacture rollforming machinery, we do sell and distribute them on behalf of our trusted partners at New Tech Machinery.However, we know there are many manufacturers and distributors to consider. And since we believe that being an informed and educated consumer is the best way to make the right buying choice, we’ve put together a collection of some of the best portable and in-plant metal roof rollforming machine manufacturers.(Note: Manufacturers are listed in no particular order.)

1. Purpose: Suitable for longitudinal shearing of metal strips, and rewinding the slitted narrow strips into rolls.2. Advantages: convenient operation, high cutting quality, high material utilization, and stepless speed regulation of the cutting speed.3. Structure: It consists of unwinding (unwinding), leading material positioning, slitting and slitting, coiling (rewinding), etc.4. Applicable materials: tinplate, silicon steel sheet, aluminum strip, copper, stainless steel sheet, galvanized sheet.5. Applicable industries: transformers, motors, home appliances, automobiles, building materials, packaging industries, etc.Slitting machines are divided into parallel blade shears and oblique blade shears. Parallel blade shears. The two blades of this shearing machine are parallel to each other. It is usually used for transverse shearing of blooms (square, slab) and other square and rectangular section billets, so it is also called billet shearing machine. This type of shearing machine sometimes also uses two forming blades to cold cut rolled parts (such as round tube blanks and small round steel, etc.), and the shape of the blade is adapted to the cross-sectional shape of the cut-and-rolled part. Oblique blade shearing machine. The two blades of this shearing machine, the upper blade is inclined, the lower blade is horizontal, and they are at a certain angle to each other. The inclination of the upper blade is 1°～6°. This kind of shearing machine is often used for cold shearing and hot shearing of steel plates, strip steels, thin slabs and welded pipe billets. Sometimes it is also used to cut small steel into bundles.

Slitting steel is essentially, a cutting process. Large rolls or coils of steel are cut lengthwise to create strips of metal that are narrower than the original in width. This is an automated process where the master coil is run through a machine that has very sharp rotary blades, one upper and one lower, often called knives.While the knives, clearly, are key to the process the un-coiler, knives and re-coiler must all be aligned and set correctly (knife clearance and uncoil/recoil tension levels are critical) in order to avoid problems. Dull knives along with a bad set-up can lead to burred edges, edge wave, camber, crossbow, knife marks, or slit widths that don’t meet specs.Another basic processing application is blanking. A blanking line will uncoil the material, level it, and cut it to a specified length and width. As a result, a blank normally goes directly into the manufacturing process without being re-sheared. In order to achieve the desired tolerance, blanking lines utilize a close tolerance feed system, side trimmers and in-line slitters.Cut-to-length lines are generally thought of as systems that produce sheets. Sheets are cut to a standard size and typically re-sheared at the end user. In order to achieve flatness tolerances, cut-to-length equipment needs to have precision corrective levelers. These levelers elongate the steel beyond its yield point (the amount of stress the steel can take at the onset of permanent deformation) in order to remove internal stresses and produce a flat sheet.
