Microlap is a leading US manufacturer of precision orifices made of synthetic ruby and sapphire, silicon nitride, ceramic and other hard materials. We mechanically drill each orifice to reduce material fatigue often caused by laser drilling; our exclusive "Micro-Rolled" lapping process provides polished radiuses for superior stream consistency.
