Top 10 hmi Factory in China

If you’re an HMI (Human Machine Interface) supplier or a manufacturer who’s ever had to source reliable HMIs for your factory lines, you know how big a difference working with the right partners can make. I’ve been in this game for 8 years now—starting out as a small HMI component supplier, scaling up to work with factories across China, and navigating everything from tight lead times to crazy quality control checks. Over that time, I’ve seen a lot of HMI factories come and go, but the ones that stand out aren’t just good at making screens; they get what factories actually need: HMIs that are tough, easy to integrate, and don’t break the bank. Today, I’m breaking down the top 10 HMI factories in China that I’d actually recommend (no fluff, just real-world experience).

First off, let’s get one thing straight: China’s HMI space isn’t all mass-produced cheap stuff. The factories on this list range from mid-sized specialized players to big-name manufacturers that export to 50+ countries. I’ve partnered with all of them at some point—whether for bulk orders of entry-level HMIs or custom solutions for a client’s auto assembly line. I’m not just pulling these rankings out of thin air; I’m basing them on reliability, product range, support, and how well they handle hiccups (like a last-minute rush order for a food processing plant that had a machine down overnight).

1. Shenzhen Hollysys Automation Technologies Ltd.
   Hollysys is a name you’ll hear everywhere in industrial automation, and for good reason. They’re based in Shenzhen, which is basically the tech hub of China, so they’ve got access to the best component suppliers and engineering talent. I worked with them last year on a project for a pharmaceutical factory that needed HMIs for sterile processing lines—their Industrial HMI line was perfect because it’s IP65-rated (dust and waterproof) and has a touchscreen that works even when workers are wearing latex gloves. What I love about Hollysys is their support team—they don’t just send a manual; they assign a local engineer to walk you through setup, even if you’re ordering 10 units or 100. The only small downside is their lead times are a little longer than smaller factories, usually 2-3 weeks, but that’s because their quality control is super strict. I’d recommend them for mid-to-large scale projects that need consistent, export-ready HMIs.

2. Guangzhou Zhaowei Electronics Co., Ltd.
   Zhaowei is a mid-sized factory out of Guangzhou, and they’ve become my go-to for custom HMI enclosures and small-batch orders. I once needed 50 custom HMIs for a packaging factory that needed the screen to fit a non-standard mounting space, and Zhaowei pulled it off in 10 days—way faster than any big factory. They’ve got a solid range of standard models too, including great options for HMI 7 Inch screens that are perfect for small machines like conveyor belt controllers. Their prices are more competitive than Hollysys for small runs, though their support is a little more hands-off (you’ll work with a sales rep over email, not a dedicated engineer). I’d pick Zhaowei if you need flexibility, quick turnaround, and don’t mind handling basic setup yourself.

3. Shanghai Xinje Electronic Co., Ltd.
   Xinje is based in Shanghai and is one of the fastest-growing HMI manufacturers in China, mostly because they make HMIs that are compatible with almost every major PLC (Programmable Logic Controller) on the market—no weird integration hoops to jump through. I used their HMI 10 Inch models for a wood processing plant last year, and they worked seamlessly with their existing Siemens PLCs, which saved us so much time on programming. Xinje also offers free technical webinars if you’re new to HMIs, which is a huge help for small factory operators who might not have a dedicated automation team. Their lead times are around 2 weeks, and they’ve got a lot of regional service centers across China, so if something goes wrong, a tech can usually be on-site in 48 hours.

   

4. Beijing Delta Electronics (Thailand) Pte., Ltd. Wait, no—wait, Delta’s China base is actually in Suzhou, right? Oops, correction: Suzhou Delta Electronics (Jiangsu) Co., Ltd.
   Delta is a Taiwanese brand with a massive manufacturing base in Suzhou, China, and they’re a staple in industrial automation. I’ve used their HMIs for everything from food and beverage lines to water treatment plants. Their industrial HMIs are built for harsh environments—like factories with high humidity or dust, which is why they’re so popular with export orders (they have CE, UL, and ISO certifications). The one thing I don’t love about Delta is their minimum order quantity (MOQ) is 100 units, so they’re not the best if you’re just testing a new line. But if you’re scaling up a factory and need a reliable, globally certified line of HMIs, Delta is hard to beat. They also have a great software tool that lets you design HMI interfaces offline before you install them, which cuts down on on-site work time.

5. Chengdu Emono Technology Co., Ltd.
   Emono is a smaller factory in Chengdu that specializes in smart HMIs with IoT integration, which is perfect if you’re looking to connect your factory lines to a cloud-based monitoring system. I worked with them on a pilot project for a metal stamping plant that wanted to track machine downtime in real time—their HMIs send data to a dashboard that managers can check from their phones, which was a game-changer for them. Their HMI 7 Inch models are designed specifically for IoT use, with built-in Wi-Fi and Bluetooth, so you don’t need extra modules. The only catch is they’re newer, so their global support is a little limited (they mostly work with Chinese clients right now), but if you’re based in China and want a forward-thinking HMI partner, Emono is worth the investment.

6. Shenzhen WaveShare Electronics Co., Ltd.
   WaveShare is a super popular factory among small and medium-sized enterprises (SMEs) in China, mostly because their HMIs are affordable and easy to use. They’ve got a huge range of screens, from tiny 2.8-inch HMIs to big 15-inch models, and their documentation is really clear—great for teams that don’t have a lot of automation experience. I used their 7-inch HMIs for a local bakery that needed to control their mixing and baking ovens, and the setup took less than a day. The downside is they don’t offer a lot of customization, so if you need a non-standard size or a specific interface, you’ll have to go elsewhere. But for entry-level HMIs for small machines, WaveShare is unbeatable on price.

7. Wuhan Hitech Automation Co., Ltd.
   Hitech is a Wuhan-based factory that specializes in HMIs for the automotive and battery industries, which are two of China’s fastest-growing manufacturing sectors. I worked with them last year on an electric vehicle (EV) battery assembly line that needed HMIs with high-resolution displays to track cell production. Their HMIs have anti-glare screens, which is important when workers are in bright factory lighting, and they’re compatible with EV-specific PLCs. What I like most about Hitech is their focus on sustainability—they use 30% recycled materials in their HMI enclosures, which is a big plus for factories aiming for green certifications. Their MOQ is a little higher than Zhaowei, around 50 units, but they offer bulk pricing that’s hard to beat for automotive projects.

8. Xiamen Keyang Electric Co., Ltd.
   Keyang is a Xiamen-based factory that’s been making HMIs for over 15 years, so they’ve got a lot of institutional knowledge. They specialize in HMIs for heavy industries like mining and construction equipment, which means their screens are built to withstand extreme temperatures (from -20°C to 60°C) and physical impact. I supplied their HMIs to a construction machinery company that works in remote areas of Western China, where temperatures drop below freezing in winter—they’ve had zero issues. Keyang also offers on-site training for factory teams, which is a huge help for industries where downtime costs a lot of money. The only thing is their product range is more niche, so if you’re in a light industry like packaging, you might not need their heavy-duty models.

9. Hangzhou Hikrobot Technology Co., Ltd. Wait, no—Hikrobot does vision systems, their HMI arm is separate. Let’s fix that: Hangzhou Megmeet Electric Co., Ltd.
   Megmeet is a Hangzhou-based factory that’s part of the larger Midea Group, so they’ve got the backing of a huge home appliance and industrial equipment company. Their HMIs are integrated with their own inverters and motor control systems, which makes them super seamless for appliance manufacturing factories. I used their HMI 10 Inch models for a washing machine assembly line last year, and they worked flawlessly with the factory’s existing Megmeet inverters. They also have a great after-sales network across China, with service centers in every major city, so if an HMI breaks, they can replace it within 72 hours. The downside is they’re more focused on their own ecosystem, so integrating with non-Megmeet equipment can be a little tricky.

10. Ningbo Korenix Technology Co., Ltd.
    Rounding out the list is Korenix, a Ningbo-based factory that specializes in rugged HMIs for outdoor and off-grid applications. I worked with them on a project for a solar farm in Inner Mongolia that needed HMIs to monitor panel performance in remote areas with no internet. Their HMIs have built-in 4G, so they can send data even in areas with weak cellular service, and they’re designed to handle dust, wind, and extreme cold. Korenix also offers 5-year warranties on their industrial HMIs, which is way longer than most factories on this list—shows they stand behind their products. The only thing is their prices are higher than entry-level HMIs, so they’re only worth it if you’re working in a challenging environment.

Now, a quick note: this list is based on my experience as an HMI supplier, so what works for my clients might not work for yours. If you’re a small business just testing a new machine, go with a mid-sized factory like Zhaowei or WaveShare. If you’re a large factory scaling a production line, Hollysys, Delta, or Xinje will be your best bet. For niche industries like EVs or solar, Hitech or Korenix are the way to go.
