Stretch forming is a type of metalworking most commonly used in aerospace applications. During the metal stretch forming process (also known as ‘wrap forming’), metal sheets or extrusions are stretched to exceed their inherent elastic limit and formed around contoured dies to create the desired shape. This “stretching” results in an increased material yield strength and a stronger finished part. Since stretch forming machines maintain constant tension of the metal throughout the process, they minimize imperfections and wrinkles.

Roll forming—also stylized as roll-forming or roll forming—is a metalworking process that employs a series of rolls to continuously bend a coil of sheet metal until it has the desired profile. The rolls come in sets that are mounted on consecutive stands to facilitate the forming operation. As the strip—typically made of coiled steel—runs through the sets of rolls, each set incrementally produces a bend in the material.

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.

The main difference is that while rolling forces the metal to flow into a different shape, sheet metal forming works by causing deformation in the material overall, with minimal effect on the grain structure or the thickness of the material.

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.

A steel cut to length machine is also called the CTL line machine, cut to length lines, and heavy gauge lines. The steel cut to length machine is used for unrolling and cutting the heavy gauge strip material into the desired length, creating the final profiles. The steel cut to length machine is utilized for applications in the food and beverage industry, electronics, and construction equipment today. The CTL line machine typically processes the wide steel coils with high-performance cutters that can cut to precision lengths, quick tooling change system, decoiling, and stacking systems to produce the steel sheets or steel plates. Some cut to length machines also involves recoiling systems to achieve unique contours. 

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.

LINBAY MACHINERY exported this machine to Argentina. This machine is capable of producing two different sizes of the OMEGA version. On each shaft we have installed two sets of wheels, one set of wheels to produce one size. The cutting knives are also of special quality with two sizes on one knife.
