21 Years of Silicone Innovation — Our Story

In August 2005, Cui Delin — a veteran with deep roots in China's organic silicone industry — founded Shenzhen Yuanfeng Xingye Technology Co., Ltd. with a single conviction: that silicone, the world's most versatile food-safe material, could be engineered to genuinely improve everyday life.

What began as a small team in Shenzhen has grown into a nationally recognized high-tech enterprise with a 4,500 m² factory, 20+ specialized machines, 300+ granted patents, and a client roster that spans Walmart, Disney, Nike, Nestlé, and the FIFA World Cup. Through every stage of growth, our founding principles have remained unchanged: integrity, quality, and genuine partnership with our customers.
 

Founding Vision — Why Silicone?

Chairman Cui Delin chose silicone for reasons that still define us today. Unlike plastic, food-grade silicone is biologically inert, free of BPA, phthalates, and heavy metals. It withstands temperatures from −40 °C to +230 °C without degrading. It is recyclable, long-lasting, and safe for direct food and infant contact. In 2005, most Chinese manufacturers were treating silicone as a commodity. We saw it as a precision material with untapped engineering potential.

That insight drove our earliest R&D investment: proprietary silicone compound formulas and mold design capabilities that let us engineer products most factories could not. Today, three of our invention patents cover silicone formulations for antimicrobial properties and infant-grade safety — a direct expression of our founder's original vision.
