The company was officially founded. Meanwhile, an R&D laboratory for ultrasonic transducers was set up, establishing the technical roadmap of independent core sensor technologies. Within the same year, our first open‑type ultrasonic sensor was released, making us one of the early domestic enterprises that mastered piezoelectric ceramic matching and acoustic structure design for ultrasonic transducers.
Building upon open‑type sensors, the company overcame challenges in potting processes and sound‑transparent materials, and took the lead in launching waterproof‑type ultrasonic sensors rated IP67/IP68. These products meet the requirements for outdoor deployment and harsh working conditions, and provided initial verification of our integrated “transducer + structure” design capability.
Initiated the self‑development of >200kHz high‑frequency ultrasonic transducers, breaking through narrow beam and high‑sensitivity reception technologies for precision liquid level and small object detection.
A dedicated ultrasonic‑specific IC design team was set up. By deeply integrating front‑end weak‑signal processing, temperature‑compensation algorithms and transducer drive circuits, we realized full independent control from the transducer physical layer to the signal‑processing layer.
We released our first general‑purpose ultrasonic sensor for industrial automation featuring self‑developed adaptive threshold algorithm, offering an initial alternative to base‑series sensors from Pepperl+Fuchs and SICK.
Via strategic spin‑off, Hengchuang Business Division runs independently for industrial automation and high‑end scenarios. The Algorithm & AI Perception Laboratory was launched for multi‑target recognition, anti‑interference filtering and IO‑Link protocol stack research.
As China’s first enterprise with full‑range industrial‑grade ultrasonic sensor offerings, our product lines are fully benchmarked against Pepperl+Fuchs, SICK and microsonic. Hengchuang stands out from domestic peers with complete full‑stack in‑house development capabilities across transducers, hardware circuits and algorithm & bus communication technologies.
The programmable ultrasonic sensor series featuring built‑in algorithm firmware libraries was released. Software‑based configuration allows adaptation to various scenarios, achieving “one hardware platform, multiple intelligent functions”.
Leveraging self‑developed ultrasonic array sensing and beamforming algorithms, Hengchuang pioneered an on‑line bulge inspection system for plywood. It slashed equipment cost by over 80% to the 100‑thousand‑RMB level. Thanks to full‑stack R&D advantages, the system gained large‑scale adoption among plywood producers, solving drawbacks of manual inspection. Guided by “technology democratization”, it brings world‑class ultrasonic detection to SMEs and fuels industrial upgrading.
Realized independent iteration for transducer, circuit and algorithm core modules. Sustained leadership in product reliability and special‑scenario adaptability, providing deeply customized sensing solutions for industrial automation, intelligent logistics and new‑energy industries.
