Import Blank Crystal — Buy in Bulk from Supplier in China

The Blank crystal from Meiyun (Wuhan) Craft Technology Co., Ltd. is a precision-cut optical blank made from K9 borosilicate glass, a material known for its 91% light transmittance and low iron content. Each blank is polished to a surface finish of 20-10 scratch-dig per ISO 10110-7, with dimensions typically ranging from 50mm to 150mm in diameter and thicknesses between 10mm and 30mm. These dimensions are suitable for engraving, laser etching, and mounting in display fixtures without requiring secondary machining.

K9 crystal is a standard optical glass in the decorative and award industry, offering higher refractive index and dispersion than regular soda-lime glass. The blanks are free of bubbles, striae, and inclusions visible under 10x magnification. Surface flatness is held within ±0.05mm per ISO 10110-5, and edges are lightly bevelled to prevent chipping. The material is not tempered or coated; it is supplied in its native state to allow for custom engraving or polishing by the buyer.

These blanks are primarily purchased by trophy manufacturers, corporate gift suppliers, and custom engraving studios in North America, Europe, and Southeast Asia. Buyers typically order in quantities of 500 to 5,000 pieces per shipment, packed in foam-lined cardboard boxes with dividers. Trade terms are offered as FOB Wuhan or CIF port of destination. Lead time for standard sizes is 14 to 21 days after deposit, and payment is accepted via T/T or L/C. No certifications are claimed by the supplier beyond material composition.

Meiyun (Wuhan) Craft Technology Co., Ltd. operates from a facility in the Wuchang Technology Pioneer Center in Wuhan, Hubei Province. The company is listed as a harbor-tier supplier, indicating verified business registration and factory location. No information is provided about years in operation, employee count, or export history. The supplier's profile confirms production capability for optical crystal blanks but does not state certifications, client names, or revenue figures.

The company's focus appears to be on manufacturing blanks for downstream customization rather than finished products. The address is consistent with industrial zones in Wuhan known for glass and crystal processing. There are no public records or third-party audits referenced in the listing. Buyers should verify production capacity and quality control processes directly before placing bulk orders.
