Minamida Corporation employs rolling and tapping technologies to form essential screws and serrations on workpieces manufactured through cold forging. Rolling uses two flat or round dies to form screws or serrations on the workpiece's outer diameter. In contrast, tapping uses a specialized tool to form screws on the workpiece's inner diameter, achieving precise machining necessary for fastening and fitting parts together. These technologies significantly improve the assembly and reliability of products.

Features
The greatest feature of Minamida's rolling and tapping technology is its ability to form high-precision screws and serrations without compromising the strength of workpieces produced by cold forging. In particular, screw forming through rolling processing utilizes the material flow, allowing for stronger and more durable screws compared to those made by cutting. Tapping creates precise internal screws, enabling the production of products that meet various fastening requirements.

Specifications
Rolling processing directly applies dies to the workpiece's circumference under pressure to form the desired screw shape or serrations. Tapping processing, on the other hand, involves rotating a specialized tap tool inside the workpiece's inner diameter to form precise internal screws. These processes are used to manufacture precision joint components for a wide range of fields, including automotive parts, electronic devices, and industrial machinery.

Minamida Corporation's rolling and tapping technologies significantly contribute to improving the quality and production efficiency of joint components in the manufacturing industry. These advanced processing techniques enhance product reliability and performance, boosting the competitiveness of the manufacturing sector. In all industrial sectors requiring precise screw forming, Minamida's technology demonstrates its value.
