Company profile
A factory, not a trading house
Everything published on this site describes what the manufacturer makes and publishes. Where a figure is not published — floor space, headcount, capacity — it is not stated here either.
Dongtai YILON Industrial Co., Ltd. was founded in 2014 and is based in Sizao Town, Dongtai City, Jiangsu Province, China. The company manufactures airtight & waterproof zipper manufacturing across 9 published product ranges and 60 published sub-models.
YILON is a National High-Tech Enterprise, which reflects a focus on research and development rather than assembly alone. The company runs its own R&D team and holds multiple technical patents. Its airtight and waterproof zippers are rated IPX6 to IPX8, with airtight builds published at a 60 kPa sealing-pressure reference and a durability figure of 3,000+ open/close cycles.
Products are exported to more than 30 countries and regions, with long-term supply relationships with more than 300 enterprise clients worldwide. The company also takes part in international exhibitions.
What the R&D work is for
Airtight zipper problems are rarely solved by a catalogue part. The published capability is in-house R&D plus OEM/ODM production: size and tape width, length and effective opening, colour, slider type and count, opening style, material and coating, waterproof rating and oil resistance, and test requirements — all produced to the project rather than picked off a shelf.
