Our Background
2018
Established in 2018, we began with sapphire component manufacturing, focusing on precision windows and custom sapphire parts.
2019
From 2019, we expanded into international trade business, serving global customers with reliable sapphire processing solutions.
Capacity Expansion
Production capacity has been continuously expanded to support flexible quantities, stable quality and long-term supply.
Sapphire Process Steps
1：X‑Ray NDT Crystal orientation apparatus
First, crystal orientation is verified via X‑ray non‑destructive testing. Markings are applied strictly according to customer‑specified crystal‑axis requirements.
2：Sapphire Brick Cutting
The sapphire ingot is precision‑sliced. The blank thickness is close to final dimensions, reserving sufficient material allowance for subsequent grinding & polishing.
3：Rounding Machines
For circular components, blanks are centred and edge‑rounded to achieve required roundness and outer‑dimensional tolerances.
4：Grinding Room
Shape‑forming completed, workpieces enter grinding phase. Single‑side or double‑side grinding is selected according to customer‑specified accuracy requirements.
5：Single‑side grinding & polishing machine
Single‑side grinding delivers superior surface quality and is deployed for high‑specification optical components.
6：Double‑sides grinding & polishing machine
Double‑side grinding processes both faces simultaneously for higher throughput, delivering excellent parallelism for mass‑production orders.
7：Manual Chamfering
Precision chamfering eliminates edge chipping during machining. It also prevents operator cuts during part handling and assembly.
8：Fine grinding process workpiece
After coarse grinding, components proceed to fine grinding to tighten thickness, flatness and parallelism tolerances.
9：Thickness Measuring
Post fine‑grinding, every part is measured for thickness. Polishing removes minimal material, so fine‑grinding dimensions must fall within finished‑part tolerances.
10：Polishing Room
Passing fine‑grinding inspection, parts move to polishing. Single‑side or double‑side polishing is chosen based on target surface‑quality grades.
11:Double Polishing Room And Ultrapure Water Equipment
Double‑side polishing optimises throughput for high‑volume orders with moderate surface‑quality requirements, eliminating bonding‑plate‑related process steps.
12:Single Side Polishing
Ultra‑high‑precision optics utilise single‑side polishing. Multiple iterative processing cycles are needed, which accounts for higher pricing for premium‑grade sapphire components.
13：Dimensions Checking
Post‑cleaning, finished parts go through comprehensive quality inspection. Full‑process monitoring covers dimension, roundness, parallelism, perpendicularity, angle and flatness.
14：Surface Quality Checking
Microscopes and standard optical inspection lamps detect surface scratches, digs and blemishes for optical‑grade acceptance.
15：Surface Flatness Checking Water Equipment
Laser interferometers are used to quantitatively test workpiece flatness and parallelism.
16：Packing And Delivery
Qualified components are packed with capacitor paper, individually sealed in ziplock bags, housed in rigid PP boxes and outer cartons. Global shipments via DHL are available.
