ABOUT XINKEHUI
One materials partner
from crystal to delivery.
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.

05 / SHAPED PARTS
Shaped sapphire windows
Polygonal, stepped, drilled or special-profile parts produced to an approved drawing.
Send your drawing ↗WHERE IT WORKS
Built for demanding light,
heat and wear.
Sapphire combines high hardness, chemical stability, electrical insulation and broad optical usefulness. We help translate those material benefits into parts that fit your equipment.
Semiconductor & LED
Substrates, carriers and inspection parts where crystal orientation, flatness and surface condition matter.
Optical sensing
Protective windows for cameras, pyrometers, spectroscopy and analytical instruments.
Laser & photonics
Low-scatter, polished windows and coated components for controlled transmission.
Industrial protection
Hard, corrosion-resistant viewports and covers for harsh temperature or abrasive environments.
Material note
Final values depend on grade, orientation, geometry and process route. We quote to the drawing and inspection plan.
WHY XINKEHUI
Precision is a process,
not a promise.
Our job is to make the handoff between engineering, production and delivery feel simple and repeatable.
01
Specification clarity
We align material, orientation, diameter, thickness, surface, coating, quantity and inspection before release.
02
Flexible customization
From standard wafers to shaped windows, we support drawing-based review and small-batch validation.
03
Stable delivery rhythm
Packaging and repeat-order checkpoints are documented so approved programs can move with fewer surprises.
04
Commercially practical
We combine direct coordination with qualified domestic supply partners to balance lead time and cost.

FAQ
Useful answers before
you send the drawing.
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.
Which crystal orientations can you supply?
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.
What wafer diameters are available?
Common programs cover 2, 3, 4, 6 and 8 inch wafers. Other sizes can be reviewed against yield and tooling requirements.
Can you provide SSP and DSP finishes?
Yes. Single-side polished and double-side polished surfaces can be quoted with target roughness, TTV, bow and warp.
Can shaped sapphire windows be made from a drawing?
Yes. Round, square, polygonal, stepped and drilled windows can be reviewed from a 2D drawing or 3D file.
Do you offer AR or protective coatings?
Coating options can be matched to UV, visible or IR bands and the application environment. The final stack is confirmed before production.
What affects lead time?
Size, tolerance, finish, coating, quantity and inspection scope all affect the schedule. We confirm a production plan after reviewing the specification.
How are parts cleaned and packed?
Parts can be cleaned, separated and packed in trays, cassettes or vacuum-compatible packaging as required.
Can you provide inspection records?
Inspection records may include dimensions, thickness, surface quality, flatness metrics, coating data and visual inspection photos.
What applications use sapphire windows?
Typical applications include optical sensors, high-temperature viewing ports, laser protection, semiconductor tools, camera covers and analytical instruments.
How do I request a quotation?
Send the target size, orientation, thickness, finish, quantity, coating band and delivery destination through the form or WhatsApp.
