JNTC Plans Vietnam Glass-Platter Output for Seagate in 2027

JNTC plans to start making glass platters for Seagate hard disk drives at its Viet Tri, Vietnam, factory in the first quarter of 2027, then expand deliveries in the second quarter. The schedule would add a new product line for the South Korean glassmaker’s storage business.

JNTC converted its third factory in Viet Tri from making glass covers for wearable devices and vehicles. The work began in late 2024 and involved an investment of about 55 billion won. The site’s mass-production line is complete, with annual capacity of about 120 million to 170 million pieces.

The company expects the operation to begin contributing revenue in the first quarter of 2027 and estimates several hundred billion won in additional sales each year. JNTC plans to prioritize Seagate’s demand before 2030, then pursue customers including Western Digital and Toshiba.

Over the longer term, JNTC aims to raise annual capacity to 400 million to 500 million pieces.
