Manufacturing
Eight stages. Zero shortcuts.
Inside the Sunny Ceramics manufacturing pipeline — engineered for repeatable, export-grade quality.
01
Design & Engineering
CAD modeling, hydraulic flow simulation and CNC mold prototyping.
02
Ceramic Molding
High-pressure casting in vitreous-china slip across automated lines.
03
Drying Process
Climate-controlled tunnels remove moisture without surface stress.
04
Surface Finishing
Hand sanding, edge refinement and pre-glaze surface inspection.
05
Glazing
Triple-coat robotic glaze tunnels for a mirror-grade ceramic finish.
06
High-Temperature Firing
1200°C kilns transform raw bodies into vitrified, non-porous ceramic.
07
Quality Inspection
Visual, dimensional, water-flow and load-bearing tests on every batch.
08
Packaging & Export
EPS-cushioned cartons, container loading and global shipping documentation.
