The process of metal rolling is technically defined as ‘a metalworking technique of plastically deforming metal by passing it between a pair of rolls.’ This method helps in changing the cross section of a piece of metal. This method is one of the four common types of bulk deformation processes—with the other three being drawing, forging and extrusion.
Rolling is used for manufacturing rolled cylinders. It is a preferred process for forming useful components such as cylinders, tubes, pipes and rings. These components can be formed in several different sizes and dimensions.
Cold rolling is a process that is used when good dimensional accuracy and the desired surface finish are a concern. This process is carried out below the re-crystallization temperature of the metal. This is a more common method in the metal forming and metal working industry, and can be used for manufacturing pipes and tubes from metal sheets, strips, plates and rods. Cold metal rolling can be carried out in a single pass, and sometimes, several rollers are used in a series to achieve the desired results.
There are several different types of rolling processes that are used in the metal-working industry. Some of the most popular and effective ones are—ring rolling, roll bending, roll forming, profile rolling, and controlled rolling. Each of these types has its unique advantages, and can be used with different materials such as copper, brass, stainless steel, aluminum, and steel. The final components can be finished in a variety of options.
Another metal forming process that is commonly used is deep drawing. As part of the deep drawing process, a sheet of metal is formed into a three dimensional shape by using processes such as hydroforming or punching. This process is used for manufacturing cans, tanks, housing for components, vessels and sinks.
Here are some important things to remember while choosing a metal rolling service provider:
- While placing an order for rolled metal products, it is vital to ensure that your chosen firm meets prevailing industry standards such as ASME and AWS.
- Choosing a firm that offers international delivery of finished components ensures that you can get the consignment sent to your off shore manufacturing or assembly units. It’s fair to expect a typical delivery time of around 4 weeks to 12 weeks depending on the nature and volume of your order.
- Speaking of volumes, there are certain firms that do not accept small batch production. This might not always work in your interest. Hence, you might want to choose a firm that can offer you volumes from 1 part (where feasible) to 50,000 parts if so required.
- It is important to choose a metal rolling service provider that has a wide and varied client portfolio.
