Manufacturing · Three Production Bases
From self-supplied raw glass fiber in Inner Mongolia to a fully automated new plant in Chuzhou — one wet-laid process, digitally controlled end to end.
Where Alpha Beta started. Separator production, the R&D center and the central quality inspection center on the Yangtze — the company's technical home for over thirty years.
Our own micro glass fiber production feeds our separator lines — raw-material self-supply that most converters don't have, controlling quality from the fiber itself.
A 20,000 m²+ site in the Chuzhou National Economic & Technological Development Zone, one hour from both the Nanjing and Hefei industry clusters. Fully automated lines and smart warehousing — 8,000 t/year of our 18,000 t total.
The wet-laid process
From micro glass fiber to packed roll. Select a step — the red markers are the five key QC control points locked in our control plan.
Raw micro glass fiber — self-supplied from our Inner Mongolia base — and process water are charged to the line to a recipe set per customer spec.
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
The wet-laid step: dilute fiber stock sheets onto the forming net and is dewatered evenly, so fibers settle into a flat, uniform web.
Stock concentration — the core of thickness consistency
Forming net speed — fixed per 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 on the big-axis slitter to customer plate dimensions, with light-table inspection for appearance defects along the way.
Slit material is wound into rolls. In-line thickness measurement runs continuously here, feeding the control center and closing the loop back to the forming section — how we hold ±5% tolerances roll after roll.
Finished rolls enter the warehouse. At Chuzhou, a smart warehousing system tracks every pallet from line to container.
Cut to length, counted and labelled per each customer’s specification documents, then export-packed for sea and air freight.
Every line reports to the manufacturing control center — live daily and monthly output, completion rate, pass rate, equipment utilization and raw-material stock on one wall of dashboards.
In-line thickness measurement closes the loop back to the forming section in real time.
R&D runs alongside production: raw material enhancement, AGM for start-stop application, pasting paper for automotive, and Stranmat. Customized separator development for specific battery designs is a standing service. See the quality system
The Chuzhou plant runs a photovoltaic system across its roofline and a zero-discharge industrial wastewater installation. Process-water purity is verified in our ICP program — it's a separator quality parameter, not just an environmental one.
We host customer audits and technical visits at all three bases. Tell us your dates — Chuzhou is one hour from Nanjing.
