The process of metal rolling enables the creation of cylindrical objects by passing a sheet of metal through a pair of rolls to attain the desired contours. This method is considered to be a key-enabler for obtaining components such as tubes, pipes, and cylinders in various dimensions and sizes. This process is carried out with the help of sophisticated machines in order to attain the desired curves and angles.
Cold rolling of metal is a process that is carried out at room temperature. There are several reasons why this method is the preferred choice. Here are some of these:
- This process helps create neat and clean cylindrical shapes that need very little finishing operations. The surface finish is much better as compared to other processes. Time and money required to be invested in subsequent processes can be saved.
- The cold roll forming process is proven to be highly effective as it provides accurate results. The best part about this process is that it’s suitable for low volume as well as high volume forming requirements.
- Different types of metal sheets, plates, strips and rods can be used for creating tubes using the cold metal rolling process.
- Another advantage is that the cold rolling process doesn’t reduce the thickness of the metal. And, this process can be carried out in a single pass, thus eliminating the need for repeatedly passing the metal through rollers.
Types of cold roll forming methods and materials used
There are various types of cold roll forming processes that your chosen metal forming and fabricating services company might suggest. Some of the commonly used types of roll forming processes include: controlled rolling, profile rolling, roll forming, roll bending, and ring rolling. Each of these methods has its unique advantages depending on the exact component required.
There are several different types of metals that can be put through the cold roll forming process. Some examples of metals that are suitable for this process include carbon steel, aluminum, stainless steel, copper, brass, and certain other alloys. Typically, the cold rolled products measure under 0.25” in thickness. However, this mainly depends on the length of the cylinder and the type of material being used.
Deep drawing is another popular press operation that creates a cavity in a sheet of metal. In the deep drawing method, the sheet metal is pushed into a forming die using a punch.
Thus, when you choose a services firm for your metal rolling requirements, you might want to verify whether they meet standards such as the ASME and AWS, and the typical expected delivery time in addition to other technical specifications. Firms that have tie-ups with logistics firms for honoring international delivery requirements have a definite edge over others.
