The company runs a distinctive 'materials + equipment' integrated solutions model, coupling its resin portfolio with system integration offerings such as valve-array multi-port systems, simulated moving bed (SMB) chromatography, high-throughput industrial preparative chromatography, EPC engineering, and customized technical services. End markets span life sciences/biopharmaceutical purification (including antibody and peptide/oligonucleotide synthesis), new energy metals (salt lake direct lithium extraction, gallium/rubidium/nickel/cobalt recovery), water treatment (nuclear-grade and electronic-grade ultrapure water), food and plant extraction (juice, sugar alcohols, organic acids, CBD), chlor-alkali, chemical catalysis, and environmental remediation (VOCs removal).

Commercial model is direct enterprise field sales with pricing quoted per specification and volume; cumulative dividends since the 2015 ChiNext IPO exceed CNY 1.1 billion across more than ten distributions, and operating revenue for the first three quarters of 2025 reached CNY 1.933 billion with total assets of CNY 6.414 billion. The company sells to 100+ countries, has 200+ system installations delivered, and recently (2025–2026) expanded its European footprint via a Sweden subsidiary and acquired a strategic stake in Tianjin Fengxinze Technology to extend into biopharmaceutical chromatography systems.
