Addressing the pain points of existing fiber cement production lines—high energy consumption, low efficiency, and poor stability—we offer a full-chain refurbishment and upgrade service, encompassing on-site diagnosis, solution design, equipment upgrades, and commissioning and acceptance. During the on-site diagnosis phase, our technical team conducts 3-5 days of production line operation data collection and equipment testing to accurately pinpoint efficiency bottlenecks. In the solution design phase, we combine the client's production capacity needs and budget to provide multiple upgrade paths, including core equipment replacement, intelligent system installation, and process parameter optimization. For example, for a client's aging production line put into operation in 2015, we increased production capacity by 40%, reduced unit energy consumption by 25%, lowered equipment failure rate by 60%, and achieved a return on investment (ROI) of up to 18 months by replacing the intelligent filter press, installing online monitoring equipment, and implementing an intelligent control system. Our refurbishment and upgrade services have covered over 50 existing production lines in more than 20 provinces and cities across China, helping clients achieve a leapfrog upgrade in production line efficiency at the lowest cost.
