Project Introduction
Project background:
A veterinary drug manufacturer and listed company whose main business is veterinary drug preparations has two production bases. One plant started an equipment upgrade project in 2025 to further improve line automation and product quality standards. For premade pouch packaging, the company already uses DIKAI's customized pagination machine with the DLU500X laser coding system, which runs stably with good results. Roll-film packaging is spread across three workshops with several Dewo vertical packers that currently use Markem X40 coders to print production date, expiry date and batch number. To improve coding efficiency and mark quality, sharpen the product image and reduce coding defects, the company launched the roll-film coding upgrade project at the end of 2025. Based on the production process, product characteristics, on-site space and customer needs, this plan provides a systematic solution combining coding and inspection to keep the equipment running stably and fully meet customer needs.
Customer pain points:
1. Complex working environment: the products are powders, and the site has heavy dust and corrosive sugar. The existing equipment is not well adapted and long-term stability is hard to guarantee. 2. Mark quality and product image: the X40 marks have weak adhesion and are easily erased during production flow, causing packaging appearance defects and failing the consistency and aesthetics the customer expects. 3. Operating cost and after-sales service: X40 consumables and spare parts are expensive and service response is slow, raising overall operating cost and downtime risk. 4. Limited installation space: the installation area is narrow, so new equipment must be compact and space-saving. Customer needs and solution: 1. Compliance and environmental friendliness: the equipment must run stably and comply with national and industry regulations. The zero-consumables design has no chemical emissions and meets green production requirements. 2. Coding quality and adaptability: the system must adapt to film of multiple sizes and print precisely in the designated position, with clear, high-adhesion and rub-resistant marks that stay durable and traceable. 3. Defect detection and linked control: if the coder is abnormal or a code is missed, blurred, missing or wrong, the system must detect it in real time, output an error signal to the packaging machine and reject automatically. 4. Full automation: coding, inspection and packaging run in a fully automatic linked flow, minimizing manual intervention and improving continuity and stability. 5. Service and technical support: responsive after-sales service for fast troubleshooting, plus long-term technical support and spare parts supply.
DIKAI coding solution:
1. System composition: integrated laser coding plus vision inspection delivers efficient, permanent marks and closed-loop quality control through online vision inspection. 2. Laser selection: continue with the DLU500X laser system, already proven in other workshops for stability and environment adaptability. A 70mm x 70mm field lens enables embedded installation in the tight space while keeping the marking range and accuracy. 3. Vision selection: the Keyence IV4 smart vision system is compact with built-in AI learning and strong anti-interference for long-term stable operation. 4. Installation structure: custom brackets and control cabinet made to the actual site dimensions fully use existing space without extra floor area or large-scale renovation.
Project highlights:
1. DIKAI lasers are widely used in the pharmaceutical industry. 2. With the DIKAI vision system, 100% online monitoring of coding quality is achieved. 3. Deep linkage of coding, inspection and packaging builds a fully automatic closed loop that reduces manual intervention and improves line efficiency.
