Factors to Consider When Buying a Metal Straightening Machine

Straightening machine is a device that can be used to straighten or bend metals. It is commonly used to correct the wavy and curly edges of sheet metal, preventing them from becoming damaged by cutting or punching processes. It can also be used to straighten other types of deformed metal, such as I-beams or square bars. It is a forming process that involves using sets of rollers to alternately stretch and compress the upper and lower surfaces of a flat piece of metal, exceeding its yield point in order to straighten it. It is important to note that different metals, such as steel vs aluminum, have different yield points and there is no one-size-fits-all solution for straightening.

In addition to the type of metal you’re working with, the thickness and width of your product will influence the straightening capability of your machine. The maximum width of a straightener is limited by the ability of the pinch rolls and end journals to resist the shear stresses produced by the material being processed. This is a function of the diameter of the work rollers and the centre distance between them. The optimum straightening capability of a machine can be established by setting the entrance side pinch rolls to the minimum depth required for the given material, while raising the exit side rollers to a higher penetration.

The resulting shear stresses are concentrated at the center of the rollers, where they are located farthest from the bearing and journal surfaces. This causes the rollers to deflect. Excessive deflection causes a loss of contact surface area, reduced straightening efficiency and in severe cases, marked or broken material. It is possible to reduce this tendency by establishing the desired pinch roll pressures through an air pressure regulator or screw down and gauge combination.

For those looking to minimize heat damage to their hair, there are a number of irons that use nano-ceramic and tourmaline plates. These plate technologies reduce friction and release a low amount of moisture while straightening, helping to keep your hair healthy and glossy. These types of irons are typically more expensive than those that use traditional metal plates, but they can save you time and money in the long run by reducing the amount of styling needed to get your hair into the style you want.

Another factor to consider when selecting a straightener is how portable it will be. If you are going to be traveling a lot with your straightener, you may want a smaller and lighter version that is easier to pack and carry. The BaByliss Pro Nano Titanium 1.5-Inch straightener is a good option, weighing in at just 300g and having a compact size that makes it easy to slip into a tote bag or purse. The heat settings are easily accessible on the face of the iron, and the plates are 1.25 inches wide to help you get more hair straightened in each pass and to cut down on styling time.
