In the afternoon, the industrial area outside Dubai was shrouded in a dim yellow. The strong wind whistled past with fine sand, hitting the metal exterior wall of the factory with a crackling sound. In the workshop, Li Ming, the technical director of the ply-pack factory, was debugging a newly assembled device with his team. He stroked the seam of the fuselage with his hand and said to the engineer next to him: "The sealing strip here must be tightened by another 2 mm. Sand grains can penetrate everywhere. What customers want is foolproof."
This scene is a daily microcosm of the sandstorm protection packaging equipment developed by the ply-pack factory to cope with the sandstorm environment in the Middle East. The core of this type of equipment lies in the innovation of the sealing structure. It adopts a three-layer staggered silicone ring design and a dynamic air pressure balance system. Even in an environment with a dust density of up to 300μg/m³, it can ensure that the dust content in the packaging cabin is less than 5μg/m³. A purchasing manager of a UAE food company lamented during the acceptance: "Our nut production line used to lose 12% of finished products every month due to dust pollution. Now the equipment has been running for three months and the return rate has been directly reduced to zero." From research and development to mass production, supply chain collaboration has become the key. The factory cooperated with German material suppliers to develop a high-temperature resistant and anti-static composite coating that can resist the penetration of fine dust below 50μm; while local Saudi logistics companies have optimized transportation routes and compressed the delivery cycle of precision components from 35 days to 18 days. "Sandstorms are not a problem of a single link," Wang Li, head of the supply chain, emphasized at an internal meeting, "From the material of the bearing dust cover to the electrostatic adsorption technology of the packaging film, every detail needs to be synchronized upstream and downstream." The demand for change in the industry is driving the upgrade of technology direction. The frequent strong sandstorms in the Middle East in recent years have exposed traditional packaging equipment to hidden dangers such as motor jamming and sensor misjudgment. The ply-pack factory's sandstorm protection packaging equipment has a targeted modular design. Customers can freely change the filter level according to the dust concentration. At the same time, it is equipped with an AI environmental perception system to adjust the internal air pressure of the equipment in real time. A medical consumables company in Kuwait reported: "In the past, the circuit board had to be shut down after each sandstorm. Now the system will automatically trigger the double sealing mode, and the continuity of the production line has increased by 40%." Standing on the observation deck on the top floor of the factory, General Manager Zhang Yuan looked at dozens of roaring prototypes in the test area. There was a line of words written on his notebook: "Fighting against wind and sand is essentially a race against time." Below it was a photo sent by a customer - in the yellow sand, the equipment printed with the ply-pack logo was still running stably, and the surface of the packaged precision instrument box was as smooth as new.
