Introduction

Beijing Daheng Image Vision Co., Ltd. (北京大恒图像视觉有限公司), commonly known as Daheng Image, is a Beijing-based technology company specializing in machine-vision components, automated inspection equipment, visual-information systems, and related software. Founded in 1991, it operates as a core business of the listed Daheng Technology group, whose shares trade on the Shanghai Stock Exchange under code 600288.

The company occupies an important position at the intersection of industrial automation, digital imaging, and plastics-processing quality control. Its technologies are used to inspect printed materials, pharmaceutical packaging, labels, bottles and containers, electronic products, and other manufactured goods. Within the plastics industry, Daheng Image is particularly relevant to flexible packaging, films, labels, molded containers, and high-speed production lines where automated detection of defects, dimensions, print quality, and surface conditions supports process consistency and material efficiency.

Daheng Image combines cameras, lenses, illumination, image-acquisition hardware, image-processing software, algorithms, and application-specific inspection machinery. Its development has followed the broader evolution of machine vision—from component supply and image processing toward integrated systems incorporating industrial computers, automation controls, and artificial-intelligence-assisted inspection. The company has also developed inspection solutions for banknotes, labels, flexible packaging, pharmaceutical packaging, and other specialized products.

History and Development

Daheng Image was established in 1991 and adopted a technology-development-oriented model from its foundation. The company developed a combined research, manufacturing, and commercial structure through which image-processing technologies could be converted into industrial products.

Important stages in its development include:

• 1991: Establishment of the company in Beijing and commencement of work in image-vision technologies.
• 2002: Reported achievement of ISO 9001:2000 quality-management certification, marking the formalization of quality procedures for its engineering and production activities.
• Expansion into integrated inspection: The company broadened its activities from image-vision components and processing technologies into complete inspection systems for printing, packaging, pharmaceutical products, containers, electronics, and other manufacturing applications.
• Internationalization: Daheng Image has marketed inspection equipment and related products in more than 30 countries and territories, according to exhibition and company materials.

Its development reflects a wider transformation in manufacturing inspection. As production lines have become faster and product specifications more demanding, manufacturers have increasingly substituted or supplemented manual inspection with camera-based systems capable of continuous, repeatable, and traceable measurement.

Business Operations and Segments

Daheng Image’s activities can be grouped into several closely related areas:

The company’s integrated approach is significant because industrial inspection normally requires more than a camera or software package. Production environments demand coordinated optical design, line synchronization, mechanical integration, defect libraries, operator interfaces, and communication with manufacturing-execution or plant-control systems.

Products and Technologies

Machine-vision components

Daheng Image supplies or develops core components used in industrial-vision installations, including:

• Industrial cameras and intelligent cameras
• Image-capture and image-processing boards
• Factory-automation and closed-circuit-television lenses
• Optical accessories
• LED light sources and other illumination equipment
• Laser-related optical components
• Vision software and algorithm packages

These components support applications involving two-dimensional imaging, high-speed line scanning, dimensional measurement, surface inspection, character recognition, and comparison against reference images. Proper selection of camera resolution, exposure time, lens geometry, lighting wavelength, and line speed is central to reliable inspection.

Printed-material and packaging inspection

Packaging inspection is a major application area. Systems can be configured to identify defects such as:

• Missing or duplicated print
• Registration errors
• Color or density deviations
• Smudges, streaks, scratches, and contamination
• Incorrect text, symbols, or barcodes
• Die-cutting and slitting errors
• Wrinkles, holes, and other film defects

For flexible packaging and labels, inspection equipment is generally integrated with web-handling or rewinding machinery. The system must maintain image stability while material moves continuously at production speed. A typical configuration combines line-scan cameras, controlled illumination, encoder synchronization, image-processing software, and mechanisms for marking, rejecting, or recording defective sections.

Daheng Image has also publicized label-rewinding equipment with software-assisted knife setting, slitting functions, first-piece PDF comparison, automatic modeling, and artificial-intelligence-related enhancements to inspection algorithms.

Container and pharmaceutical-packaging inspection

The company’s application portfolio includes inspection of bottles, containers, and pharmaceutical packaging. Such systems may evaluate dimensional features, closure or cap position, label placement, print content, surface contamination, and other attributes that influence product acceptance.

For cylindrical or irregularly shaped products, inspection design can involve multiple cameras, controlled rotation, telecentric optics, backlighting, or specialized illumination. In pharmaceutical and regulated packaging, inspection systems also contribute to traceability by recording images, defect classifications, and production results.

Banknote, ticket, and security-print inspection

Daheng Image has developed inspection technologies for banknotes, commercial tickets, and other security-related printed materials. These applications typically require high-resolution imaging, precise registration analysis, detection of subtle printing deviations, and controlled handling of confidential or high-value products.

The technical requirements of security-print inspection overlap with those of premium packaging and label production. Both fields depend on accurate comparison with approved artwork, detection of small defects, and reliable operation across long production runs.

Image-processing architecture

A complete Daheng Image system may include:

1. Optical and lighting design suited to the product surface.
2. Area-scan or line-scan cameras selected for the required resolution and speed.
3. Image-acquisition hardware and industrial computing.
4. Defect-detection, measurement, and classification algorithms.
5. Mechanical integration with conveyors, printing presses, rewinders, fillers, or packaging lines.
6. Interfaces for alarms, marking, rejection, reporting, and production control.

The effectiveness of such systems depends on the relationship between hardware and software. A high-resolution camera cannot compensate for unstable web handling or unsuitable illumination, while sophisticated algorithms require consistent image quality and carefully defined acceptance criteria.

Applications and End Markets

Daheng Image serves manufacturing sectors in which visual quality, dimensional conformity, authenticity, or production traceability are important. Identified application areas include:

• Flexible packaging films and laminated materials
• Labels and printed packaging
• Pharmaceutical packaging
• Bottles, jars, and other containers
• Printing and commercial-ticket production
• Banknotes and security printing
• Electronic-product manufacturing
• Textile and cotton inspection, including foreign-fiber detection
• Medical imaging and healthcare information systems

For plastics processors, the company’s systems can support inspection of extruded films, printed webs, laminated packaging, injection-molded containers, caps, and other products. Machine vision is particularly valuable where defects are intermittent, production speeds are high, or product geometries make manual inspection inconsistent.

The company’s role is therefore primarily downstream and enabling rather than that of a polymer producer or plastics converter. It contributes to the plastics ecosystem by helping processors and packaging manufacturers control output quality, reduce waste, verify printed information, and automate release decisions.

Global Presence and Market Position

Daheng Image is headquartered in Beijing, with its principal address at Daheng Technology Building in the Haidian District. Its products and systems have been promoted in international markets, and company-related exhibition material reports sales of inspection products in more than 30 countries and territories.

The company participates in industrial exhibitions associated with printing, packaging, electronics, pharmaceuticals, and plastics-related manufacturing. Its presence in these channels reflects the cross-sector nature of machine vision: the same fundamental technologies can be adapted to different substrates, production speeds, defect classes, and regulatory requirements.

Its competitive position is based less on a single standardized product than on the combination of:

• Locally developed vision hardware and software
• Application-specific inspection engineering
• Integration with production equipment
• Experience in high-speed printed-material inspection
• Ability to supply both components and complete systems
• Adaptation to Chinese manufacturing environments and export applications

The market remains competitive. Daheng Image operates alongside specialized machine-vision manufacturers, automation-system suppliers, optical-component producers, printing-equipment companies, and international inspection-system providers. Differentiation depends on detection accuracy, line speed, system stability, software usability, integration capability, service response, and total cost of ownership.

Research and Development

Research and development is central to Daheng Image’s operating model. The company describes itself as a high-technology enterprise focused on image-vision research, product development, and commercialization.

Its development activities encompass:

• Camera and image-acquisition technologies
• Optical and illumination configurations
• Image-processing software
• Defect-detection and classification algorithms
• High-speed web inspection
• Automated equipment integration
• Medical image processing
• Artificial-intelligence-assisted inspection functions

Exhibition materials describe a research-and-development team of more than 100 people and identify proprietary innovations in banknote, label, and flexible-packaging inspection. In practical terms, continued development in this field requires improvements in sensor resolution, processing speed, algorithm robustness, calibration, data management, and the ability to distinguish genuine defects from acceptable product variation.

Artificial intelligence is becoming an increasingly important development direction. Machine-learning methods can assist with variable surface defects, complex patterns, and defect categories that are difficult to define using fixed rules. However, industrial deployment still requires representative training data, stable validation procedures, explainable acceptance criteria, and controls against false rejects and missed defects.

Sustainability and Environmental Initiatives

Machine vision can support environmental objectives indirectly by improving manufacturing efficiency. In plastics and packaging production, automated inspection may help reduce:

• Scrap caused by undetected defects
• Rework and customer returns
• Material consumption associated with repeated production
• Waste from incorrect printing, slitting, or packaging
• Energy use associated with producing nonconforming goods

These benefits depend on how systems are implemented and operated. Inspection equipment itself consumes electricity and may require computing hardware, lighting, replacement components, and maintenance. Environmental performance therefore depends on the full production system rather than on inspection technology alone.

For packaging manufacturers, the strongest sustainability contribution generally comes from earlier and more accurate detection of process deviations. Detecting a defect near its point of origin can prevent the continued production of large quantities of nonconforming film, labels, or containers.

Financial Performance and Economic Impact

Daheng Image is a subsidiary or core operating asset associated with Daheng Technology rather than an independently listed public company. Publicly available company and exhibition materials emphasize its technologies, products, and applications rather than presenting a complete standalone financial profile.

Its economic contribution is reflected in the engineering and supply-chain activities surrounding machine vision. These include research and development, optical and electronic component production, software development, system integration, installation, technical support, and maintenance. By automating inspection, its systems can also influence the productivity and quality economics of printing, packaging, pharmaceutical, electronics, and plastics manufacturers.

At group level, the company benefits from the resources and corporate structure of Daheng Technology. Its performance is consequently connected to investment in industrial automation, demand for packaging quality, export manufacturing, pharmaceutical production, and the broader adoption of digital factory systems.

Quality Management and Certifications

Quality management is a significant requirement for inspection-system suppliers because their equipment can influence product release, production efficiency, and regulatory compliance. Daheng Image has reported ISO 9001:2000 quality-management certification and has been recognized as a Beijing high-technology enterprise over multiple years.

For customers, system quality extends beyond formal certification. It also involves:

• Optical calibration and repeatability
• Stable operation at production speed
• Consistent defect classification
• Traceable software and parameter settings
• Maintainable mechanical and electrical design
• Clear procedures for system validation and change control

These considerations are particularly important for pharmaceutical packaging, security printing, and other applications in which inspection records and controlled operating parameters may form part of the customer’s quality system.

Innovations and Future Outlook

Daheng Image’s future development is linked to several structural trends in the plastics and manufacturing industries:

• Greater use of automated inspection on high-speed production lines
• Demand for shorter production runs and rapid product changeovers
• More complex packaging graphics and variable data
• Growth of traceability and digital quality records
• Adoption of artificial intelligence for difficult-to-classify defects
• Integration of vision systems with factory automation and manufacturing software
• Demand for lower scrap rates and more efficient use of raw materials
• Expansion of inspection into films, batteries, medical products, and advanced electronics

A major opportunity lies in combining inspection with closed-loop process control. Rather than merely identifying defective products, future systems can provide structured process data to printing presses, extrusion lines, rewinders, fillers, and other equipment. Such integration can shorten response times and help prevent recurring defects.

The principal technical challenges include maintaining accuracy across changing materials and lighting conditions, reducing false alarms, validating artificial-intelligence models, protecting production data, and providing reliable support across international markets. Success will depend on the company’s ability to combine specialized application knowledge with scalable software and robust hardware.
