Precision Processing Components

Core Pin


Adamant has been producing ‘’ferrules’’ for fiber optic connectors and ‘’bonding capillaries’’ for semiconductor equipment using our high precision ceramic injection molding technology. In order to keep tight tolerances for the inner diameter, we have also developed an ultra high precision core-pin.

We can provide core-pins (with or without a step) per end users specifications, made by an ultrafine particle hard alloy.
