Core Insertion Hole-Making Technology by Slurry Casting Method

Using a mold improves hole precision and process efficiency.

1. The mold is assembled with multiple wires/rods.
2. By pulling out the wires/rods after molding, precise hole arrangement is achieved.
3. Finally, it is sintered to be vitrified.

50 μm Ultra-Fine Hole

The slurry casting method enables ultra-fine holes that are difficult to achieve by drilling.
We have achieved hole formation with a minimum diameter of 50 µm.
