Repeatable Precision
Printing one piece well is not hard. Printing one million pieces, each identical to the first — that is the baseline of the precision printing industry.
17+ Years of HMI Printing Expertise
Dedicated solely to precision printing for human-machine interface applications.
High-Volume Multi-Category Output
10M nameplates + 50M labels + 1M film switches/month, stable delivery across mixed product types.
Top-Tier Quality Systems
IATF 16949 + ISO 9001 certified – IATF holds<1% penetration in precision printing industry.
Global Customer Reach
Serving 3C, home appliance, medical, and industrial brands across Europe, Americas, Japan, Korea, and Southeast Asia.
The Meaning of Our Existence
Precision-printed products are the "features" that the users first come into contact with when they see and touch a product. But precisely this aspect is the one that is most likely to be underestimated within the supply chain.The material was chosen incorrectly, the texture was not right, the backlight was uneven, and the labels fell off... Any minor flaw will make the entire product seem cheap. And we have been doing this for 17 years.
A good HMI printing supplier is not merely:
- Printed Clearly and Attached Firmly.
- The Sample Has Passed the Verification Once, and the Mass Production Will Not Break Down.
- It Is Still Possible to Obtain the Same Supplier's Quotation Three or Five Years Later.
- If There Is Any Problem, We Won't Shirk Responsibility. We Will Take the Initiative to Provide a Solution.
Proofing Equals Mass Production
The same production line, same parameters, same batch. ERP + MES records every process. Once the sample passes, parameters are locked — no transfer-line defect increase.
Fully In-House Process
Screen printing, adhesive coating, stamping and die-cutting all in one factory. Engineering team conducts structural compatibility analysis before prototyping.
Compliance Is Designed
6 major certifications (ISO 9001/14001/45001/14064/IATF 16949/QC 080000). IATF adoption rate in precision printing is less than 1% — we have it as our daily baseline.
17-Year Material Expertise
Clear understanding of PET, PC, 3M, and conductive silver paste lifecycles. Alternative solutions prepared in advance. If your product is still in demand in 10 years, we can still supply it.

Customer Trust
The common choice of growing global industrial brands.
We've sourced membrane switches from KeyPadOne for our home appliance control panels since 2019. Their consistent quality and on-time delivery have made them our go-to HMI supplier. The IATF 16949 certification gives us confidence for our automotive-grade projects as well.
- Sourcing ManagerSmart Home IoT Company
Our medical diagnostic equipment requires absolute reliability. KeyPadOne's touch panels have passed every validation test we threw at them — from harsh chemical resistance to 100,000+ cycle durability. Their engineering team also helped optimize the circuit layout, saving us 15% on BOM cost.
- R&D DirectorMedical Device Manufacturer
We only ordered 200 sets of custom nameplates for our initial IoT device pilot. Most suppliers would have turned us away, but KeyPadOne treated us like a key account from day one. One years later, we're ordering 50,000 units per batch and the quality has never slipped.
- Product ManagerSmart Home IoT Company
Our industrial controllers operate in high-temperature, high-humidity environments. KeyPadOne's membrane switches with custom dome embossing design have near-zero failure rates after 3 years in the field. Their CCD inspection reports come with every shipment — full traceability.
