From 32 Vacuum Coaters to a Global One‑Stop Surface Finishing Benchmark – Redefining “Surface Value”

A decade of focus. With PVD vacuum coating at our core, we’ve integrated CNC, polishing, and laser engraving – delivering not just coatings, but the “highlight moment” for every product surface.

When a smartphone button glides under your fingertip, when a smartwatch case reflects a deep, premium luster, when an automotive logo stays brilliant through heat, cold, and wear – these “invisible crafts” are the everyday miracles created by Kunshan Yingliyue Electronics Co., Ltd.

Why do leading brands choose Yingliyue? Because we turn “surfaces” into “solutions”

Surface finishing is never just a final coating – it is the decisive battleground for product performance, feel, and longevity. Since our founding in 2012 in Kunshan High‑tech Zone, we have grown from a modest 800 m² PVD vacuum coating workshop into three factories, 32 vacuum coaters, nearly 200 skilled team members, and over 50,000 m² of integrated production space – a story of relentless focus and breakthrough.

We are not a “do‑a‑little” supplier. We are a one‑stop solution provider.
CNC → Grinding & Polishing → PVD/DLC Coating → Laser Engraving → 100% Inspection – five core processes seamlessly connected. With just a drawing or a sample, Yingliyue returns a perfectly finished component that has passed through thousands of quality checks.

Three factories, three leaps: From “good coating” to “full process ownership”

• 2012 Kunshan Yingliyue – Started with PVD vacuum coating. After eight years of deep cultivation, we became a technology hub for vacuum coating in East China.

• 2020 Kunshan Polishing Base – In response to customer needs, we added 40 flat lapping machines and 10 cleaning lines, making mirror‑finish surfaces a standard.

• 2021 Nantong Wonengcheng Electronics – Full process integration: CNC, polishing, PVD, laser engraving. Daily capacity exceeds 3,500 sets for three‑piece assemblies – from raw material to finished part, all under one roof.

Every expansion is not just about scale – it is a qualitative leap in vertical integration. Today, Yingliyue provides a closed‑loop service from incoming material to full inspection and shipment for five major industries: mobile phones, computers, wearables, automotive, and medical devices. Our customers no longer need to coordinate three different factories.

Technology is not a slogan – it is backed by 30+ patents and an ISO/IEC 17025‑level lab

At Yingliyue, R&D is never an “add‑on” – it is a must‑have. We hold over 30 granted patents, and multiple invention patents have been transformed into high‑volume production processes. From Private Technology Enterprise to High‑tech Enterprise, from ISO9001 to IATF‑16949 (the automotive industry’s strictest quality standard), and also ISO14001 and ISO45001 – every certification is a cornerstone of customer trust.

Even more critical: we have built our own fully equipped testing center:
Nano‑indentation tester, nano‑roughness tester, CMM, 2.5D profiler, 1000x microscope, cross‑sectioning device, constant temperature & humidity chamber, UV aging tester…
Every batch goes through five inspection gates: incoming inspection, in‑process sampling, post‑unloading check, 100% final inspection, and outgoing inspection. Quality is not shouted – it is measured, data point by data point.

The “hit products” you know – many carry Yingliyue’s fingerprint

Open our customer casebook, and it reads like a who’s who of premium electronics and automotive:

• Apple – iPhone buttons, side button lapping, vibration motor iron cores – micron‑level tolerances, mirror‑grade finish.

• Xiaotiancai (iFlytek) – PVD coating for Z9 smartwatch cases – wear‑resistant, skin‑friendly, no fading.

• Beats – Headphone hinges, charging port decorative parts – delicate metallic texture, durable through repeated plugging.

• Huawei – Phone earpieces, speaker meshes, watch cases – from matte to high‑gloss, precisely capturing every design language.

• Xiaomi, OPPO, OnePlus – Pop‑up cameras, USB‑C ports, laptop hinges – high‑difficulty 3D parts with industry‑leading coating uniformity.

• Automotive – Mercedes‑Benz keys, BOS speaker grilles, Hongqi H9/LS7, Tank 500, BMW X1, Lotus Eletre, Volvo S90, Hozon Neta… We don’t just coat – we understand the extreme demands of automotive parts: weather resistance, corrosion resistance, and wear durability.

One‑to‑one customization – not just service, but “collaborative R&D”

Many customers first ask us “Can you do black coating?” After a conversation, they discover we can help them optimize front‑end CNC roughness, adjust polishing to reduce distortion, and even recommend better base materials. That is the true meaning of Yingliyue’s one‑stop solution:

✨ Tailored processes for special properties – ultra‑hard, anti‑fingerprint, antibacterial, insulating, skin‑feel… whatever function you need, we deliver it through coating design.
✨ Assistance with upstream & downstream processes – we analyze your incoming material issues and anticipate your downstream assembly pain points.
✨ Dedicated project manager from trial to mass production – one single point of contact, rapid response, no delays.

Looking ahead: PVD at the core – becoming a global value engine for surface finishing

“To become a globally outstanding surface finishing provider” – this is not a slogan on a wall, but a reality happening every day inside our 32 coaters. In the next three years, Yingliyue will continue to invest in high‑durability DLC coatings, optical‑grade PVD, and eco‑friendly pre‑treatment processes, while expanding into advanced automotive smart surfaces and medical implant coatings.

We don’t chase trends. We make every product’s surface the starting point of a trend.

Let your next product exceed expectations – starting from the surface.
