Quality Control
Named resin suppliers, testing against EN and ASTM methods, and what we will tell you when something goes wrong.
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.
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.
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.
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.
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.
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.
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.

A manufacturer. We extrude sheet on seven production lines at our own plant in Jiangsu and machine it on 22 CNC centres. Annual capacity is 20,000 tonnes.
Not in standard production. We buy virgin granules from Covestro, SABIC and Mitsubishi Chemical under long-term agreements. Recycled content is the cheapest way to cut cost in this industry and the hardest for a buyer to detect until the sheet yellows two or three years later.
Order samples — A4 pieces of standard grades are free. Compare them edge-on against sheet from your current supplier; recycled content shows as a grey-yellow cast in the edge, which is the hardest place to hide it.
More than 30, across Europe, North America, Australia, the Middle East and Asia. We quote in USD on FOB, CIF or DDP terms from a minimum of 100 m² or 1 tonne.
Resin supplier certification and batch traceability as standard. Our internal technical standards for optical, impact and weathering performance are aligned to EN and ASTM methods. For a specific certified test against a named standard, tell us which one before you order.
