From automotive and aerial vehicles to medical equipment, roofs and more, sheet metal has countless applications. As a result, the sheet metal manufacturing industry is thriving. According to the Bureau of Labor Statistics (BLS), the number of workers employed in the sheet metal industry is expected to grow by 9% through 2024. In 2016, roughly 139,000 workers were employed in the industry. Within the next seven years, however, the BLS expects over 150,000 workers to be employed in the sheet metal industry.
Workers use a variety of tools to form and finish raw metal into sheet metal, one of the most important being a rolling machine. What is a rolling machine, and what role does it play in sheet metal production?
A rolling machine is a piece of manufacturing equipment that contains two or more rollers through which raw metal is fed. The purpose of rolling machines is to compress raw metal into a thinner and more uniform shape, which is essential when producing sheet metal. They feature at least one pair of rollers that compress the raw material as it’s fed. When the metal comes out of the rollers, it has a thinner and more uniform shape.
Rolling machines have been around for centuries. According to Wikipedia, the world’s first rolling machine was invented by Henry Cort in the mid- to late 1700s. While Cort’s design was very basic, it allows steel mills to produce 1,500% more metal than before.
To produce sheet metal, metalworking companies first heat up the raw metal in a large furnace. Once the metal has achieved a molten state, a worker pours the liquefied metal into an a thin ingot-shaped mold and allowed to cool.
Next, a worker feeds the ingot through the rollers of a rolling machine. Each pair of rollers compresses the ingot, allowing for a thinner and more uniform shape.
After the metal has been rolled, it’s often annealed. This involves heating the metal back up and allowing it to cool. The purpose of annealing is to remove stresses and, therefore, increase the strength and durability of the metal.
While rolling machines are most commonly associated with sheet metal production, they are used in other metalworking applications. For example, a rolling machine can bend raw metal to achieve unique shapes. By definition, however, rolling machines — when used in the context of metalworking — are machines that contain one or more pairs of rollers to manipulate raw metal.

A plate rolling machine can be a valuable addition to your metalworking operation. They are good for small and medium-sized businesses that need to efficiently produce a large number of plates, but would it work for your business?
That’s what Accurl is here to help you determine. Keep reading to learn what a plate rolling machine is as well as the components and features you can find on metal rolling machines. Plus, we included some different types of rolling machines to consider and the benefits you can expect for your operation.
A plate rolling machine, or plate forming machine, will roll different kinds of sheet metal into round or conical shapes. This can be highly beneficial for a variety of industries including automotive, construction, consumer goods, home furnishings, and more.
Plate-bending machine components include the top roll and lower rolls or side rolls. These are the parts that shape the metal plates into desired cones or cylinders. Additionally, these machines have a transmitting device with the gear, shaft, shaft pin, and retaining cover that ensures smooth and swift movement and the frame, drop end part, and drive system.
There are a few sheet metal rolling machine varieties that you might want to be aware of so you can select the best option for your business.
The different varieties of sheet rolling machines are generally categorized by the number of rolls, the type of power, and the pinch, but there are also some based on the geometry of the result. Here are some of the main categories to be aware of.
First, it’s important to examine the different powers. They are generally placed into two categories: hydraulic and electric. Hydraulic rolling machine construction uses a mechanical motor and is a cost-effective approach to small and medium metalworking operations.
Electric metal rolling machines, on the other hand, are typically more efficient and easier to use, making them preferred for larger operations or for businesses that plan to scale no matter how quickly.
Also known as a single initial pinch metal plate roller, these options are generally for low-volume operations but can be both electric or hydraulic. They pinch the flat metal sheet between two rolls, whole a third offset bending roll will ensure the correct bend.
They are cost-effective but do require more operation because, in most cases, they require removal and reinsertion of the sheet to prebend both ends.
These steel plate rolling machines can create more unique shapes and can have 3 or 4 rolls. They are also called double-pinch pyramid plate rolls or double-initial-pinch plate rolling machines and have a more efficient operation than three-roll initial-pinch models.
There are options available for almost any size operation from very low volume to heavy-duty sheet metal roller options. This is why they are one of the most popular styles of steel roller machines on the market today.
Four-roll steel sheet rolling machine varieties have an additional roller that pinches the plates during the rolling process. This can accelerate production times because the operator can pre-bend the leading edge, roll the cylinder or cone body, and finish off the trailing pre-bend all in the same direction.
That’s why these are often recommended for high-volume businesses or industries where both speed and precision are necessary.
Two-roll machines are small plate rollers designed for thin-gauge material, which means they aren’t recommended as heavy-duty steel plate rolling machines. However, they are swift and will roll round parts even if the metal has cutouts or holes.
One of the downsides is that they require a separate mandrel for each diameter and material thickness, but if you only need to roll a few different shapes or materials they can be fast, affordable, and effective.
Plate and sheet metal cone rolling machine models offer a lot of advantages for your business including efficiency, precision, increased output, and easy operation.
While some steel sheet rolling machine options are more efficient than others, these machines can help you boost productivity. That means more work gets done and you have the capacity for higher revenue.
Plate rolling machines are very precise and the accuracy can mean happier clientele no matter what industry you’re in. That’s why they are used in industries where accuracy is critical like aerospace or construction.
Connected with efficiency is the benefit of high-volume output. This is especially true of 4-roll steel plate bending machines, but any of these options both hydraulic and electric can help you increase output compared to manual bending processes.
Plate rolling machines are easy to use, safe, and effective. While some training is required, they are easier to use than many of the alternatives, especially models that pinch both sides because that means your team will not have to weld, and if they do the welding will be minimal.
As you can see, a plate rolling machine is a great addition to business operations in a variety of industries. They can help you produce a higher volume of highly precise bends that elevate your business and your bottom line.
