About the Factory
Seven extrusion lines, 22 CNC machining centres, 20,000 tonnes a year, and virgin resin from Covestro, SABIC and Mitsubishi Chemical.
Jiangsu Xinjincheng New Materials Co., Ltd. researches, extrudes and machines polycarbonate and acrylic sheet. We are a manufacturer, not a trading company — the sheet you buy is made on our own lines, in our own plant in Jiangsu Province, China.
The plant
Our site covers 100 mu — roughly 6.7 hectares — and runs seven imported intelligent extrusion lines with an annual capacity of 20,000 tonnes. Alongside extrusion we operate 22 CNC machining centres capable of ±0.1 mm precision cutting, 3D contour forming and micro-structure engraving.
That combination matters more than it sounds. A mill that only extrudes has to send your cut-to-size work to a subcontractor, which adds a week and a second party to blame when tolerances slip. We do both under one roof, so a finished part can leave the same building the sheet was extruded in.
Materials
We buy virgin polycarbonate granules from Covestro, SABIC and Mitsubishi Chemical under long-term supply agreements. Standard production contains no recycled or reprocessed feedstock.
This is the single biggest quality variable in this industry and the easiest place for a supplier to cut cost quietly. Recycled content shows up as yellowing, brittleness and falling light transmission two or three years after installation — long after the invoice is settled. Our sheet is specified to hold ≥ 85% light transmission after ten years, and V0-rated flame-retardant grades are made from V0 resin rather than surface treatment.
Research and development
We operate an in-house polycarbonate application research institute staffed by a cross-disciplinary team led by six PhDs, holding 23 core patents. The institute develops the functional grades that ordinary sheet mills have to buy in:
| Grade | Verified performance |
|---|---|
| Frosted / matte polycarbonate | Light transmission ≥ 88% |
| Anti-fog polycarbonate | Effective for ≥ 5 years |
| LED diffuser sheet | Diffusion uniformity > 95% |
| Flame-retardant polycarbonate | B1 rating, ignition point 580 °C, self-extinguishing |
| Hard-coated polycarbonate | Abrasion-resistant surface for glazing and guarding |
| Anti-static (ESD) polycarbonate | Surface resistivity to customer specification |
Our internal technical standards for optical performance, impact strength and weathering are aligned to EN and ASTM test methods. Sheet is verified stable from −40 °C to 120 °C: it does not go brittle in a Canadian winter and does not soften on a Gulf rooftop.
Quality control
We run quality control across the whole chain, from incoming resin to finished product — raw material certificates, extrusion line monitoring, dimensional checks against the order specification, and optical and impact testing on production samples. Third-party national testing has verified the low- and high-temperature performance figures quoted above.
Who we supply
We supply distributors, fabricators, OEMs and volume buyers in more than 30 countries. Typical customers are sheet distributors who want a factory relationship instead of a trader’s margin, fabricators who need consistent sheet for CNC work, and equipment manufacturers who need a functional grade — flame retardant, ESD, diffuser — that their local stockist does not carry.
We are a core member of the Jiangsu Bakway New Materials Group.
How to start
Send a specification or a drawing. We quote in USD on FOB, CIF or DDP terms, and our minimum order is 100 m² or 1 tonne — a trial pallet, not a container.
