An iron or steel leveler is a piece of machinery used to flatten, level, and remove internal stresses from irregularly shaped steel or iron products. The working principle of an iron leveler involves passing the material through a series of rolls that apply perpendicular forces to it, changing its shape from being wavy or rippled to flat and uniformly plain. Iron levelers can be classified based on their function and design into the following types.
Iron levelers with 3 to 7 rolls are usually used for light levels of flattening. In contrast, those with more than 7 rolls are employed for heavier levels of flattening and typically have greater load capacities.
Unlike roll levelers, straightening presses usually have only three or four roll blocks. However, they are stationary and require the passage of the object being leveled through some of its roll blocks.
Drag chain levelers are typically used for high-throughput operations in which funneling or singling out product is more important than achieving a close level of tolerance. For example, they can be used in the poultry industry to convey chicken in processing plants.
Due to the requirement of compressive force to level areas, an iron leveler and a press brake may work on the same principle, offsetting plates' and sheets' geometric irregularities. However, the primary functions of the two sets of machinery are different. The primary function of a press brake is to create bends in sheet metals with a high degree of accuracy, while the primary function of an iron leveler is to flatten sheets/plates with a low to moderate level of accuracy.
The specifications of the leveling irons differ according to the application, but some general specifications are as follows.
Proper maintenance of the leveling iron will ensure longer performance. Following the manufacturer's instructions when using and after using the leveling iron is essential. Cleaning it thoroughly after use is crucial. Most often, the uncleaned leveling iron becomes the cause of uneven asphalt. The wrong use at the wrong time can also cause irregularities in the iron that need to be leveled.
Cleaning the leveling iron with a proper solution that is not acidic will prevent rust and will be easier to level the material again. Leveling irons that are coated with a rust-preventive coating must be stored away from any moisture. Any tools or parts are needed to level an area should be clean and dry, and that will minimize the need to clean the leveler before using it again.
The following industries and scenarios use an iron plate leveler.
Construction industry
Workers use levelers to flatten steel plates before they are used to build foundations, beams, and frames of structures. They use levelers to produce high-quality steel products that will not warp or crack when used under extreme pressure or heat.
Manufacturing industry
Workers use iron plate levelers to produce iron parts and components that are flat, uniform, and stable. Manufacturing industries that frequently use levelers are the automotive and aerospace industries. They use hydraulic or mechanical levelers to ensure iron products meet quality standards.
Metalworking industry
The iron leveler is the main tool for metalworking industries. They use it to level all kinds of irregular metal slabs or plates. One leveling machine can do multiple jobs as it levels, flattens, and straightens uneven metal.
Repair service
Repair shops use small iron levelers to fix or level irregular metal parts. They may use CNC levelers for sophisticated work requiring a high level of accuracy. With the iron leveler, repair services can ensure metal components are flat before further repairs are done.
When choosing an iron leveler for sale, buyers need to consider the factors carefully to ensure it can fulfill their specific requirements in a given application and environment.
Adjustability and versatility
Business buyers need to look for a leveler that can adjust the thickness of the board according to their need. In addition, it would be ideal if the leveler can work with different types of irons.
Safety features
Safety is the foremost concern for both leveler users and buyers. Look for safety features such as thermal insulation, shutdown switches, and emergency shut-off buttons.
Quality of build materials
Business buyers need to choose leveling machines made from high-quality materials that are corrosion resistant and have long-lasting durability.
Operating method
It is vital to check the operating mode of the leveler prior to purchase. Buyers can find levels with operating methods ranging from manual and electric to foot pedals. Assuming the number of slabs to be leveled, buyers can choose the operating mode that matches their particular requirements.
Machine dimensions and weight
Consider the dimensions and weight of the leveler based on the dimensions and weight of the slab and the requirements of the ironing process. Make sure the leveler can conveniently handle the slab.
Warranty period
Warranties vary from manufacturer to manufacturer. Before making a purchase, carefully read the warranty terms to ensure the required coverage and support.
Q1: Can an iron leveler correct warped panels with a decorative side underlay?
A1: Leveling warped plywood with a decorative underlay presents a challenge because achieving the correct temperature and pressure requires careful consideration of the appearance of the board. The use of an iron may correct warping, but there is a risk of damage to the decorative layer, such as burning or melting. To avoid this, level the board at a lower temperature or put a cloth over the decorative layer while leveling.
Q2: Is there any way to prevent warping in plywood?
A2: There are ways to prevent warping in plywood, such as using a sealant or varnish to coat both sides of the plywood to equalize moisture distribution, maintaining a consistent humidity level in the room where the plywood is located, and choosing high-quality plywood. If the board is not yet purchased, opt for exterior-grade plywood, which has more adhesive layers.
Q3: Can an iron leveler fix bowled countertops?
A3: An iron can fix a bowed countertop if the material is laminate or wood. However, if the countertop is made of solid and heavy material like granite or marble, it cannot be leveled with an iron. In such cases, it is best to consult an expert and avoid using the iron, which may only cause more damage.
Q4: Can an iron leveler fix cabinet doors that don't align properly?
A4: An iron leveler can correct cabinet doors that do not align properly, provided that the doors are laminate or wood. However, if the cabinet doors are made of solid and heavy material like solid wood, it is better to adjust the hinges so that the solid doors align correctly solidly. In the case of laminate or plywood cabinets, the doors can be leveled using the hinges.
Q5: How long does it take to fix the warping with an iron leveler?
A5: Depending on the size and number of warped boards, it can take anywhere from a few minutes to several hours to fix the warping using the iron. The good thing is that leveling small boards like cabinet doors may only take a few minutes to level with the iron. In contrast, larger boards may take longer, especially if they require more than one ironing session to correct the warp.
