It will be the park’s second largest foreign project. The plant will be built in two phases, with construction beginning next quarter and completed in two years.

The company is owned by Americans Ha Vinh Ly and Nhe Thi Le, who also own Hayward Quartz Technology Inc in Silicon Valley in the U.S. It supplies a number of major original equipment manufacturers.

The largest foreign investment in the park is by the Sunshine aerospace components factory belonging to another U.S. company, Universal Alloy Corporation.
