Our History
Our Journey in Making Things Right
Fifteen years ago, we started with a simple belief: a great product begins with a perfect mold. That's how our story kicked off in 2008 in Shenzhen, as a dedicated mold and plastic specialist. We were, and still are, obsessed with getting the foundation right.
A Big Move for Bigger Dreams
By 2014, our small workshop was buzzing with bigger ideas. To turn these ideas into reality, we needed more space and better capabilities. So, we packed up our expertise and moved to Dongguan, embracing a new name – Sunny More – to reflect our brighter, more expansive future. This wasn't just a change of address; it was an upgrade of our entire promise to our partners.
More Than Just a Factory – It's Your Workshop
Walking through our 2,500-square-meter facility today, you'll see more than machines. You'll see our Silicone Team and Plastic Team working side-by-side. This is where magic happens: an idea is sketched, a mold is crafted, and a product is born, all under one roof. We built this integrated space to give you one less thing to worry about.
The 'Why' Behind What We Do
We don't just fill purchase orders. We help solve problems. Whether it's a softer silicone brush for a spa day, a protective case for your favorite gadget, or a custom component for your latest project, we pour the same care into every item. Our 60-strong team shows up every day to ensure that when you choose Sunny More, you're choosing reliability you can feel.
Let's Build Something Together
We believe the best partnerships are built on open doors and handshakes. We're proud of our home and the work we do here, and nothing makes us happier than showing it to you. Come see for yourself, and let's talk about how we can bring your next product to life.
