Baoding Sinhai Sunboard Manufacturing Co., Ltd. has specialized in polycarbonate manufacturing for over 30 years. Every custom small-format pc sheet is produced from 100% virgin Bayer or Sabic polycarbonate resin and CNC-cut to your drawing, sample, or 3D file. Available in thicknesses from 0.95mm to 25mm, these panels support tight-tolerance applications across electronics, medical devices, industrial equipment, and display systems — and ship as pre-cut, edge-finished components ready for direct assembly.
A product is a polycarbonate panel that has been made to exactly match your drawing or sample. It can be cut to any smaller size, from millimeter-scale parts to panels less than 1,000 mm.
These parts are different from regular bulk sheets because they are made for applications with tight tolerances and specific geometric needs. They are used when standard distributors can't provide the required level of precision in terms of size and when pre-cut, edge-finished parts cut down on the number of steps needed to finish the project.
Some of the industries they work with are medical devices, industrial equipment, safety barriers, signs, and custom architectural glazing.

Every sheet starts with 100% virgin Bayer or Sabic polycarbonate resin — no recycled content, no compromise on clarity or dimensional consistency.
The impact strength reaches 850 J/m, which is substantially higher than glass of equivalent thickness. This makes custom small-format pc sheet a practical choice for machine guards, safety barriers, and equipment windows where mechanical failure carries real consequences.
The co-extruded UV protective layer is 50µm thick and filters 98%–100% of UV radiation below 380nm, reducing yellowing and photo-oxidation over the service life of the panel.
Dimensional stability across a -40°C to +120°C service range — combined with a heat deflection temperature of approximately 135°C — means these panels maintain shape and tolerance under normal operating conditions.
Sinhai's in-house CNC workshop supports the full range of secondary processing operations commonly required for precision components.
Supported operations include:
CNC-machined edges are produced with diamond-tipped tooling and optimized feed rates to minimize burrs and edge stress. You can submit drawings, physical samples, or 3D files; Sinhai's engineering team reviews and confirms feasibility before production begins.
Each custom small-format pc sheet order goes through dimensional inspection, optical clarity checks, edge condition verification, and coating adhesion testing before shipment. Raw materials are inspected at intake, and a final check is completed prior to packing.
Tolerances are verified against the agreed drawing, and any non-conforming parts are identified and removed before dispatch.
These precision PC components are used across a range of demanding applications:
Each part ships wrapped in PE protective film, packed in carton or on a wooden pallet or crate, suitable for sea freight, truck, or air shipment. Logo printing on packaging is available for OEM and branded orders. Sinhai's logistics team supports customs clearance and cross-border documentation.
Q1: What is the customization range and dimensional precision?
A: CNC cutting, engraving, drilling, chamfering, and irregular machining are all supported. Standard CNC tolerance is ±0.1mm; tighter tolerances may be available on request depending on part geometry. Thickness range is 0.95–25mm, and the maximum part size is 2.1m × any length.
Q2: What is the MOQ and sampling process?
A: A sampling service of 3–5 pcs is available with a 5–7 day lead time. For formal orders, MOQ is 200 pcs or 100m² for custom-cut parts. Contact our sales team to confirm volume requirements for your project.
Q3: Why choose PC over acrylic for small electronic windows?
A: Acrylic offers slightly higher optical clarity, but polycarbonate provides substantially greater impact resistance and will not shatter — relevant for handheld devices and industrial equipment where safety and durability are priorities.
Q4: Can these sheets be cold-bent into small radii?
A: Yes. Cold-bending is supported, but the minimum bend radius must be at least 175 times the sheet thickness to avoid stress cracking. The engineering team can confirm bend feasibility based on your drawing.
Q5: How is UV-related yellowing controlled over time?
A: Each sheet is produced with a co-extruded UV protective layer that filters 98%–100% of UV radiation below 380nm, which reduces photo-oxidation and discoloration over the panel's service life.
