Keel plastic chain, also known as dragon-bone plastic chain, is a special modular plastic conveyor chain widely applied in automated production lines. Constructed from high-performance POM engineering plasticbody matched with stainless steel hinge pins, it combines flexible bending performance with solid load-bearing capacity, becoming a preferred conveying component for beverage, food packaging and logistics handling industries.
Different from ordinary flat-top chains, the unique keel-shaped interlocking structure enables the chain to achieve small-radius horizontal turning and reverse bending, which helps designers buid compact conveyor layouts without excessive transfer turntables. It can run smoothly on both straight and curvrd sections, saving factory floor space and simplifying whole-line mechanical design.
Most keel plastic chains adopt food-grade POM raw material, complying with FDA hygiene requirements. The smooth surface resists residue accumulation and supports high-pressure water washing and hot-water disinfection. No lubrication is required during normal operation, running with low noise compared with metal chains, which fits clean production requirements of dairy, bottled beverage, backed food and quick-freeze food workshops.
Wear resistance and stable operation are its core strengths. Stainless steel pins reduce internal friction between chain links, extending service life under continuous high-speed running. Modular assembly brings great convenience for maintenance: only the damaged single segment needs replacement instead of the whole chain, cutting down spare-part cost and production downtime. Customized width, special color and anti-static versions are available for diversified working conditions.
Typical application scenarios include bottle filling lines, carton and Tetra-Pak packaging transfer, food cooling conveyors, packaged goods logistics sorting, as well as pharmaceutical and electronic component handling. It works reliably within temperature range from -30℃ to +90℃, adapting to cold storage, normal-temperature workshop and partial hot-processing environments.
When selecting Keel Plastic Chain, users shall confirm working load, running speed, turning radius requirement and sanitary standard. Matching sprockets and guide rails are essential to avoid chain deviation, jamming and abnormal wear. With advantages of flexible routing, easy sanitation and low maintenance cost, kaal plastic chain keeps replacing traditional metal chains in modern automated conveying systems.
