Introduction
Roll forming machines are divided into mobile and fully automatic. In countries like Germany where labor costs are relatively high, fully automatic roll forming machines are the main choice in this market. Therefore, local manufacturers in Germany mostly produce fully automatic machines. However, there are also some semi-automatic machines for export. Roll forming machines mainly include roof tile machines, keel machines, door frame machines and other different models. The finished products produced by this machine are mostly used for roofs, steel structure houses, etc. Therefore, the market demand is very large.

CRC production ranges from simple to complex parts in many shapes and gauges.
What is cold roll forming machine?
Cold roll forming machines are utilized to shape high-strength steel components at room temperature, a process known as cold rolling. These machines are often employed to process long lengths of metal, producing a variety of metal products such as lift rails and shelving. The cross-sectional profile of the cold roll forming machinery is typically customized to meet the specific requirements of the customer. The forming kun is used to control localized processing of the material, preventing folding and wrinkling during the operation. These machines are specifically designed to address the needs of metal bending.
Key Components and Process
Uncoiler: Holds and unwinds the metal coil.
Feeding System: Guides the metal strip into the machine.
Roll Forming Mill: Consists of a series of roller dies that progressively shape the metal strip into the desired profile through multiple stages.
Cutting Mechanism: Cuts the formed profile to the required length, which can be either a flying shear or a stationary cutter.
Control System: Usually includes PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) for precise control and monitoring of the process.
How do roll forming machines work?
Roll forming machines operate by using multiple stationary rolls to continuously bend metal at room temperature, a process known as cold rolling. This method allows for steel production without the need for heating, thereby reducing production steps and saving time.
The rolls are arranged in groups, with each group bending the metal progressively more than the previous one. As the sheet enters the roll forming machine, these fixed rolls serve both to secure and bend the metal.
This process, also referred to as progressive processing, ensures high precision in the workpiece. It operates at speeds ranging from 30 to 600 feet per minute, making it ideal for high-volume production and the creation of very long parts.
As the demands on cold roll forming machines increase, including additional machining requirements such as punching, stamping, bending, locking, and even in-line welding operations, our machines are upgraded to meet these needs. This ensures that parts are produced in a single pass, enhancing productivity and practicality.
