WHO WE ARE
Guangdong Yumingsheng Precision Manufacturing Co., Ltd. -- YMS -- is a silicone product manufacturer based in Dongguan, China.
We specialize in B2B OEM/ODM silicone manufacturing for brands, wholesalers, distributors, importers, and private-label companies worldwide. We do not operate retail -- our entire operation is built around one purpose: manufacturing silicone products that meet your specifications, at scale.
