The roller-type roll-type design is designed to work in a variety of materials, rather than specific materials. According to the different materials of workpiece, the basic advantages of the cold forming of threads are not only the excellent surface quality, but also have higher static and dynamic strength. The length of the thread to be produced is not limited by the chip that must be removed. These tools have excellent stability, especially for small thread sizes. All the ink materials can be cold. Sufficient lubrication is essential. We generally recommend using oil groove through hole thread and horizontal machining (exception: very short hole threads, such as metal plates). Sometimes it is necessary to adjust the proposed drill path to the conditions of the workpiece.

IF the faucet
EE is the world’s first manufacturer of rolling faucets designed for special materials or materials. EM has designed a complete roll-type faucet, especially the special properties of single materials and materials, and sometimes increases performance in a dramatic manner. Traditional rolling valves are used for all ductile materials: in the defined applications, potential performance characteristics are simply wasted in the process. EE has conducted extensive research on the mechanism of cold forming and developed a new tool from the results. To highlight the unique feature of this highly innovative scrolling form click, we’ve come up with a new name: IIF
