Import Drill Small Holes In Sapphie, Micro Drilling Of — Buy in Bulk from Supplier in China

Jiangyin Deli Laser Solutions Co., Ltd. provides a micro‑drilling service capable of producing holes as small as 30 microns in sapphire substrates. The process supports a depth‑to‑diameter ratio of up to 20 : 1, allowing deep but narrow passages in the hard crystal. Hole placement accuracy is guaranteed at 5 microns, and the resulting sidewalls are smooth with no visible chipping. The service is delivered in batches suitable for bulk orders.

Sapphire’s Mohs hardness of 9 requires ultrashort‑pulse laser ablation, a technique widely adopted for high‑precision work on hard ceramics. Typical industry practice accepts a diameter tolerance of ±3 microns for sapphire micro‑holes, with quality verification performed by scanning electron microscopy. Compared with mechanical drilling, laser drilling eliminates tool wear and reduces the risk of micro‑fractures.

The capability is used by jewellers to create intricate settings and by electronics manufacturers for components such as optical waveguides. The supplier mentions flexible minimum order quantities, so buyers should confirm the exact MOQ that matches their project scale. Shipping terms can be negotiated under standard Incoterms like CIF Shanghai, and payment arrangements follow customary B2B practice. Prospective buyers are advised to request a detailed quotation that includes lead‑time estimates.
