Raziol is a family-owned company with over 80 years of history, based in Iserlohn in the Sauerland region. From there, the company and its approximately 140 employees develop and produce solutions for lubricants and application technology for industrial forming processes.
The focus is on applications in which metals or other materials are formed, stamped, or drawn. Areas of application are primarily found in the automotive industry, among suppliers, in the manufacture of household goods, and wherever forming is a central process step.
Lubricants play a decisive role in forming. They influence not only the quality of the components, but also tool life, process reliability, and cost-effectiveness. In addition to developing suitable lubricants, the range of services also includes the appropriate application technology. The aim is to apply the lubricant evenly, reproducibly, and in precisely measured doses. This reduces material consumption and process fluctuations, which is particularly important in automated production lines. The systems are designed to be integrated into different production environments. Whether for series production in the automotive industry or more variable applications at suppliers, the combination of lubricant and application technology is designed for consistent processes.
A central element of the solution shown is the brush cleaning system. It is used before pre-cut blanks enter downstream spray chambers or forming processes. In this step, the blanks are cleaned of solid particles that may have been created during cutting or transport. This cleaning is crucial to ensure uniform lubrication and trouble-free further processing. Cleaning is carried out using brush technology that operates during the running process. Each blank is cleaned automatically without the need for additional manual intervention. During regular operation, the machine is closed to ensure safe and clean operation. For maintenance work, it can be moved to a position where all relevant components are easily accessible.
The brush cleaning system is fully integrated into a higher-level control concept. In conjunction with the oiling system, several process steps can be implemented via a central control system. This reduces interfaces, simplifies operation, and minimizes potential sources of error. The cleaning and maintenance functions of the machine are also integrated into this concept. The heart of the system is based on proven technology that has been in use for years in the automotive sector and by various suppliers. This experience is reflected in the design of the machine, which is designed for continuous operation and high availability.
A special feature of the system is its ease of maintenance. The ability to move individual drives in a targeted manner makes it easy to reach brushes and other components. This greatly facilitates maintenance, replacement, and adjustment. In the state shown, for example, the lower brush can be lifted in a targeted manner to demonstrate how individual elements can be maintained or replaced. In operating mode, the brushes automatically move to the set board geometry. For the application shown, a board thickness of one millimeter is set so that the brushes move exactly toward each other. This automatic adjustment ensures consistent cleaning quality even with changing component dimensions.
Another key feature is the integrated crash detection system. In industrial practice, it can happen that circuit boards become deformed or enter the process in a faulty state. Without protective mechanisms, such components could cause considerable damage to the machine. The automatic crash detection system therefore monitors the process continuously. If a disproportionately deformed blank is detected, the brushes and rollers react immediately. They move apart before any damage occurs. This protective mechanism increases operational safety and reduces unplanned downtime. During normal operation, the brushes remain in their intended position; the safety function only intervenes in the event of a deviation.
The solution shown illustrates how closely cleaning, lubrication, and control are linked. Only when the blanks are clean can the lubricant be applied optimally. At the same time, precise application ensures that the forming process is uniform and material-saving. The integrated control system ensures that all steps are coordinated. Typical features of the solution shown are:
The combination of lubricants, application technology, and brush cleaning represents a holistic approach to forming processes. Instead of viewing individual process steps in isolation, they are understood as a coherent system. This is particularly relevant in the automotive industry and for suppliers, where high cycle rates, consistent quality, and low downtimes are required. By integrating all relevant functions into a consistent concept, processes can be stabilized and operated economically in the long term. The system shown is an example of this approach and illustrates how proven technology can be combined with practical safety and maintenance concepts.
