On September 10, 2025, the 26th China International Optoelectronic Exposition (CIOE 2025) opened grandly at the Shenzhen World Exhibition & Convention Center. As a leading manufacturer of vacuum coating equipment and solutions in China, HCVAC brought its latest technologies and a full lineup of optical coating machines to the show — attracting strong attention from industry professionals, customers, and partners.
HCVAC's booth was bustling with visitors on the first day. Professionals from optics, semiconductors, display technologies, and automotive electronics stopped by to learn more and discuss key topics such as:
How to achieve uniform film coatings
Ways to improve yield and process stability
The localization of high-end coating equipment
Many visitors praised the performance of HCVAC's machines and their latest process breakthroughs. Several potential clients also showed interest in building long-term cooperation.
At CIOE 2025, HCVAC presented a full suite of vacuum coating solutions for emerging fields such as optical coatings, semiconductor packaging, MEMS devices, and precision optics, including:
• E-Beam Evaporation
Featuring a proprietary RF ion source and exclusive ratio control method with multi-point in-situ monitoring, this system enables high-precision, stable deposition of optical multilayers. Coating loss is reduced by up to 30%.
• Magnetron Sputtering
Equipped with a new ICP ion source and online magnetic field adjustment, ensuring film uniformity ≤ ±1% and absorption rate < 0.1% — ideal for high-spec optical applications.
• Atomic Layer Deposition (ALD)
Designed for demanding applications that require ultra-dense, high-reliability thin films.
• Cluster Coating Systems
Flexible and modular platforms that support multi-process integration, ideal for scaling up complex multilayer structures.
In addition to equipment, HCVAC showcased its end-to-end capability across equipment, spare parts, and coating process development — helping clients transition smoothly from R&D to mass production.
CIOE 2025 is in full swing! HCVAC warmly invites industry professionals and partners to visit us at Hall 7 · Booth 7C53, where we continue to explore the boundless potential of vacuum coating technology across optoelectronics, semiconductors, and next-generation displays.
