Company History

Mold Tooling Experts

David Jon emerged as the visionary behind Haitian Import & Export in 1998. In 2003, DSW established a new company, NINGBO DSW International Co., Ltd., which supplies alarms, sirens, and plastic tooling. Like many other manufacturers, the DSW team dedicated much of their time to producing plastic molds, die-casting tools, stamping parts, and assembling PCBs for home appliances.

Since 2004, DSW Industry has specialized in manufacturing high-precision dies and plastic molds. Over time, we expanded into plastic injection molding, micro-molding, aluminum die casting, and progressive stamping. We deliver tight-tolerance, high-quality solutions to our overseas customers, ensuring exceptional product quality, competitive pricing, and outstanding after-sales service.
