The "Invisible Champion" of PVD Coating—This Kunshan Factory, 13 Years in the Making, Is Redefining the Possibilities of Metal Surfaces

Every Smooth Surface You Touch Has a Story Behind It

Have you ever wondered why the smartphone you hold every day, the smartwatch on your wrist, or even the tactile button in your car—why are they so smooth? Why do they still look brand new after a year of use? Why do they exude a captivating metallic luster under the sun?

The answer lies hidden within a film so thin, it's nearly invisible to the naked eye.

This film is only one-thousandth the thickness of a human hair, yet it can withstand 96 hours of salt spray corrosion without failure. It remains flawless after millions of touches. It gives cold metal the warmth of a soul.

And behind this film, there is a company that has been quietly cultivating this craft in Kunshan for 13 years.

Chapter 1: 13 Years, Focused on One Thing

December 2012. Kunshan Hi-tech Zone.

Back then, China's smartphone industry was just taking its first steps. PVD coating was an unfamiliar term to most people. But inside the workshop of Kunshan Yingliyue Electronics, the first vacuum coating machine had already begun its silent operation.

13 years later, that small workshop has evolved into a professional surface treatment enterprise with three production bases, 24 vacuum coating machines, and nearly 200 employees. From 1 machine to 24, from 1 factory to 3, from a dozen people to nearly 200—these changing numbers point to an unwavering direction:

Dedication to metal surface treatment. Mastery of PVD technology.

Some ask: Why not expand your business scope? Why not pursue more lucrative ventures?

Our answer is simple: Mastering one thing to perfection is far more valuable than doing ten thousand things mediocrely.

Chapter 2: From Smartphones to Pacemakers, We Coat More Than Just Metal

Yingliyue's client list includes smartphone giants, automotive brands, wearable tech innovators, and hidden champions in the medical device industry.

The mid-frame of the phone in your hand might have been coated by us.
The button on your smartwatch might have been coated by us.
The interior trim in your car might have been coated by us.
And perhaps, even the casing of a life-saving pacemaker was coated by us.

Why do they choose Yingliyue?

Because the problem we solve is never just one.

We provide: A complete one-stop surface treatment solution—from Polishing and Sandblasting, to PVD Coating, to AF Anti-fingerprint coating and Laser Marking.

This means:

• You don't need to shuttle your products between different factories.

• You don't need to argue about who's responsible for polishing defects versus coating defects.

• You don't need to worry about every detail of process integration.

You just need to hand us the design. We handle the rest.

Chapter 3: Three Factories, 24 Coating Machines—We're Playing a Long Game

Someone asked: Why build three factories? Can you really utilize 24 coating machines?

The answer is: Because our clients' needs are never one-dimensional.

• Factory No. 1 focuses on consumer electronics, serving clients in phones, computers, and wearables, pursuing ultimate aesthetics and tactile feel.

• Factory No. 2 focuses on automotive and industrial sectors, serving clients in car interiors and medical devices, pursuing stable quality and reliable delivery.

• Factory No. 3 focuses on R&D and innovation, exploring next-generation surface treatment technologies together with our clients.

24 coating machines are not just a simple accumulation of quantity. They are our "arsenal"—from magnetron sputtering equipment imported from Germany, to multi-arc ion plating equipment from South Korea, to our independently developed automated production lines. Behind every machine lies a technological barrier and a testament to client trust.

And operating these machines are nearly 200 Yingliyue people—engineers, technicians, quality inspectors, process specialists. Some have been in this industry for 20 years, others are fresh out of university. But they all share one thing: a obsession with perfection.

Chapter 4: Vision & Mission—Where Are We Going?

Over 13 years, we've navigated the difficult journey from 0 to 1, scaled up production from 1 to 24 machines, and expanded across industries from consumer electronics to automotive and medical.

But we know this is just the beginning.

Our Vision: To become a globally outstanding surface treatment supplier.

Not the "largest," but the "most outstanding." Outstanding means: technological leadership, reliable quality, trusted clients, and fulfilled employees.

Our Mission: Committed to providing clients with one-stop surface treatment solutions.

"One-stop" is not just a slogan; it's a promise. A promise that you only need to focus on product design, leaving the rest to us. A promise that every process step is managed responsibly for you. A promise that quality remains consistent from sampling to mass production.

Chapter 5: If You're Also Looking for a "Reliable" Surface Treatment Partner

PVD coating—it's not exactly difficult, but it's not exactly simple either.

Why it's "not difficult": The principles are in textbooks, and the equipment is commercially available.
Why it's "not simple": With the same equipment, the results can be worlds apart depending on who's operating it.

Where does the difference lie?

It lies in the accumulation of process parameters, in the experience of handling anomalies, in the employees' reverence for quality, and in every pitfall we've encountered and solved over 13 years.

If you're looking for a PVD coating supplier, if you're tired of dealing with polishing, coating, and laser marking separately, if you want a partner who can accompany you from sampling to mass production—

Come to Kunshan Hi-tech Zone. Come visit Yingliyue.

Take a look at our workshop. Look at our equipment. Meet our people.

Epilogue: The Invisible Coating, The Visible Dedication

In this era obsessed with "speed," we choose to be "slow."

Slow down, to coat every product perfectly.
Slow down, to serve every client attentively.
Slow down, to solidify every technological breakthrough.

Because we believe: Within the invisible coating lies visible dedication.

And this is precisely the reason Yingliyue exists.
