Achieving the world's smallest micro check valve structure.

Achieving the world's smallest micro check valve structure.

Composite of different materials that is impossible even with a 3D printer.

The interior of the cylinder, with an outer diameter of approximately 2mm, has a hollow and undercut structure, and a ball that acts as a valve is housed inside. Such a shape cannot be achieved with conventional MIM or 3D printers. With our unique μ-MIM technology, we can mass-produce complex internal structures that are impossible to achieve with traditional methods using net shape manufacturing.
