Advanced Manufacturing Layout & Equipment

Our 2,000+ square meter production workshop is divided into dedicated functional zones, forming a full closed-loop production process from raw material inspection to finished product testing:

1. Raw Material Processing Zone: Equipped with precision CNC cutting machines, automatic welding stations, and stainless steel forming equipment. All raw materials (including 304/316L stainless steel, high-pressure membranes, and food-grade piping) undergo strict incoming inspection before entering the production line, eliminating quality risks at the source.

2. Module Assembly Zone: Dedicated assembly lines for RO reverse osmosis systems, EDI ultrapure water equipment, stainless steel water tanks, and sewage treatment units. Our standardized assembly process ensures consistent product performance, while our flexible workflow supports both mass production of standard models and rapid assembly of custom-tailored units.

3. Quality Testing Zone: Every piece of equipment goes through a full-cycle test before delivery, including pressure resistance testing, water quality parameter calibration, electrical safety inspection, and 24-hour continuous operation monitoring. Only products that pass all test items can be labeled as qualified and move to the packaging stage.

4. Logistics & Packaging Zone: With dedicated packaging and loading areas, we use export-grade fumigation-free wooden cases, shock-proof packaging, and standardized loading procedures to ensure products arrive at your site in perfect condition, even during long-distance international transportation.
