The Dongguan site is SUNPNS's R&D headquarters and core manufacturing base, integrating R&D and design, tooling development, automated production lines, and an independent quality laboratory. It operates four process lines — fabric lamination, die-cutting, stitching, and heat transfer/dye-sublimation — and maintains a dedicated automation equipment department that designs and assembles production lines in-house, continuously improving manufacturing efficiency and yield. With end-to-end sampling and mass-production capability, the site handles new product development, process validation, and fast delivery for customers worldwide.
Commissioned in 2018, the Suzhou site is SUNPNS's key capacity hub in East China, focusing on stitched bags and luggage, storage products, and die-cutting orders. Equipped with standardized stitching lines and die-cutting equipment, it follows the quality control system and management standards of the Dongguan headquarters and includes a finished-goods warehousing and logistics area. This enables localized production and rapid response for customers across the Yangtze River Delta and surrounding regions, significantly shortening lead times for East China customers.
Established in Hung Yen Province in 2021, the Vietnam site was SUNPNS's first step into Southeast Asia. It operates heat transfer, dye-sublimation, and digital printing lines with independent testing capability. This overseas capacity gives customers diversified supply chain options and tariff cost optimization, and coordinates with the Dongguan and Suzhou bases to deliver synchronized supply at home and abroad, serving more than 100 partner customers worldwide on a stable basis.
