Closed Loop Automated Central Feeding System For LSZH Material Production

Our closed-loop automated feeding system is engineered specifically for halogen-free, low-smoke (LSZH) material production, ensuring contamination-free processing of sensitive flame-retardant formulations like ATH, MDH, and nano-fillers. The system delivers ±0.3% dosing accuracy while maintaining strict dust-free and explosion-proof standards.
