Dongguan facility
Precision zirconia production under one roof
Our Dongguan workshop runs high-density zirconia ceramic production with specialized sintering furnaces, diamond grinding stations, and polishing lines. Every stage is controlled to hold consistent bores and surface finish across export volumes.
Equipment and process controls are set for international jewelry brands, wholesalers, and designers who need repeatable components from one batch to the next.
From powder to polish
Five controlled stages
Each component passes through the same sequence: raw powder preparation and molding, high-temperature sintering, precision diamond grinding, and mirror-grade polishing.
Step 01
Powder and molding
Zirconia powder is prepared and formed into bead, pendant, and component blanks to set the baseline geometry.
Step 02
High-temperature sintering
Blanks are fired in controlled furnace cycles that set the ceramic structure and purity.
Step 03
Diamond grinding
Precision diamond tools shape bores and dimensions to the specified tolerances.
Step 04
Mirror-grade polishing
Surfaces are polished to a clean, consistent luster ready for jewelry assembly or finishing.
Inspection checkpoints
Checked before every shipment
Inspection covers the measurements and surface qualities that matter to international jewelry brands.
Dimensions
Dimensional accuracy
Diameters, lengths, and hole bores are measured against the approved drawing for each production run.
Surface
Luster and scratch control
Polished surfaces are checked for even luster and scratch-free finish before packing.
Integrity
Crack detection
Components are screened for cracks and structural flaws so only sound pieces leave the workshop.
