A reliable source for sapphire substrates, optical windows and precision-shaped components. From prototype quantities to repeat programs, we align crystal orientation, finish, coating and inspection to your process.

ABOUT XINKEHUI
Shanghai Xinkehui New Materials Co., Ltd. is a technology company focused on semiconductor and optical materials. We coordinate sapphire, silicon, silicon carbide, GaAs, InP, YAG and related crystal products for customers who need clear specifications, responsive engineering communication and stable delivery.
For sapphire programs, our strength is practical customization: confirm the drawing, lock the inspection points, keep the packaging consistent and build a repeatable supply rhythm.

Sapphire combines high hardness, chemical stability, electrical insulation and broad optical usefulness. We help translate those material benefits into parts that fit your equipment.
Substrates, carriers and inspection parts where crystal orientation, flatness and surface condition matter.
Protective windows for cameras, pyrometers, spectroscopy and analytical instruments.
Low-scatter, polished windows and coated components for controlled transmission.
Hard, corrosion-resistant viewports and covers for harsh temperature or abrasive environments.

Final values depend on grade, orientation, geometry and process route. We quote to the drawing and inspection plan.
WHY XINKEHUI
Our job is to make the handoff between engineering, production and delivery feel simple and repeatable.
We align material, orientation, diameter, thickness, surface, coating, quantity and inspection before release.
From standard wafers to shaped windows, we support drawing-based review and small-batch validation.
Packaging and repeat-order checkpoints are documented so approved programs can move with fewer surprises.
We combine direct coordination with qualified domestic supply partners to balance lead time and cost.

FAQ
Still deciding between a standard wafer and a custom window? Tell us what the part must do and we will help define the shortest path to a quote.
C-plane, A-plane, R-plane and M-plane can be reviewed for qualified programs. Confirm the off-angle, flat or notch details on the drawing.
Common programs cover 2, 3, 4, 6 and 8 inch wafers. Other sizes can be reviewed against yield and tooling requirements.
Yes. Single-side polished and double-side polished surfaces can be quoted with target roughness, TTV, bow and warp.
Yes. Round, square, polygonal, stepped and drilled windows can be reviewed from a 2D drawing or 3D file.
Coating options can be matched to UV, visible or IR bands and the application environment. The final stack is confirmed before production.
Size, tolerance, finish, coating, quantity and inspection scope all affect the schedule. We confirm a production plan after reviewing the specification.
Parts can be cleaned, separated and packed in trays, cassettes or vacuum-compatible packaging as required.
Inspection records may include dimensions, thickness, surface quality, flatness metrics, coating data and visual inspection photos.
Typical applications include optical sensors, high-temperature viewing ports, laser protection, semiconductor tools, camera covers and analytical instruments.
Send the target size, orientation, thickness, finish, quantity, coating band and delivery destination through the form or WhatsApp.
