Manufacturing · Two Production Bases
Our Inner Mongolia base supplies glass microfiber, and both plants use wet-laid forming. Production systems feed data to a central digital control platform.
Nanjing is our founding site and now serves as the group headquarters.
Our Inner Mongolia plant supplies glass microfiber directly to the separator lines, giving us control over raw-material quality and supply.
The Chuzhou base occupies more than 20,000 m² in the National Economic & Technological Development Zone. Automated lines and smart warehousing add 8,000 t/year, bringing total capacity to 18,000 t.
The wet-laid process
From glass microfiber to packed rolls. Select a step; red markers identify the five key QC control points defined in our control plan.
Glass microfiber from our Inner Mongolia base and process water are charged into the line according to the recipe for each customer specification.
Raw material weighing — every charge weighed against the recipe
Fiber and water are pulped into a stable stock. Mixing and beating time is standardized per raw material, protecting fiber length while reaching the target beating degree.
Mixing time — standard beating time per fiber type
In the wet-laid step, dilute fiber stock flows onto the forming wire and dewaters evenly, allowing the fibers to settle into a flat, uniform web.
Stock concentration — the core of thickness consistency
Forming wire speed — set by product specification
The wet web is dried under a controlled temperature profile, tuned per grammage and density, so the sheet keeps its strength and structure.
Drying temperature — standard values per grammage and density
The dried web is slit to the customer's specified dimensions, with in-line light-table inspection for surface defects.
Slit material is wound into rolls. In-line thickness measurement feeds data to the control center and back to the forming section to control the specified ±5% thickness tolerance.
Finished rolls enter storage. At Chuzhou, a smart warehouse system tracks each pallet from the production line to container loading.
Products are cut to length, counted and labeled to the customer specification, then export-packed for sea or air freight.
Pulping, beating, forming, drying, winding and thickness control feed data to the manufacturing control center, where output, completion rate, pass rate, equipment utilization and raw-material stock are displayed together.
In-line thickness measurement closes the loop back to the forming section in real time.
R&D covers raw-material improvement, AGM separators for start-stop batteries, automotive pasting paper and Stranmat composite mats. Custom separator development is available for specific battery designs. See the quality system
The Chuzhou plant uses rooftop photovoltaic generation and a zero-discharge industrial wastewater system. An RO treatment system supplies process water for separator manufacturing.
