In 1998, our organization diversified its business interests by investing in a specialized plating technique for electronic parts and IC transistors, which led to the establishment of Newtech Scientific Technology Co., Ltd.

In 2005, with its specialization and know-how, Sun Castle applied and integrated its expertise in manufacturing and supply chain management to invent its leading products such as digital keyless door locks. So far, Sun Castle has successfully integrated today’s modern technology with traditional methods of artistry and metalworking, in the manufacturing of fingerprint input door locks, digital code input door locks, and RFID card door locks. As such, Sun Castle gained a presence in the Taiwanese market as well as in markets throughout America, East Asia, Europe, and other regions.
