I. Order Coordination and Design Sampling (Order Initiation)
Requirement Confirmatier specifies product type (Daily Use / Architectural / Art Ceramics), specifications, material, glaze color, decoration, quantity, and delivery date.
Design and Quotation: Factduces design drawings/renderings, calculates costs and quotes, and signs contract.
Mold Making: Molds are opened according to design (mainly plaster molds); complex shapes use multiiece molds.
Sample Confirmation: Small batch trial production of samples; customer confirms and seals samples as mass production standards.
II. Raw Material Preparation (Clay Body / Glaz Preparation
Mixing: Weigh raw materials such as kaolin, feldspar, and quartz according to the formula.
Ball Milling / Stirring: Add water aball mill to a fine slurry (fineness meets standards).
Screening and De-ironing: 2 screenings 2 de-ironing processes to remove impurities.
ter Pressing / Kneading: Filter press dehydration → rough kneading → aging (15 days) → fine kneading; clay body is uniform and bubble-free.
Glaze paration
Mixing → Ball Milling → Screening (2 times) → De-ironing (3 times) → Aging for standby.
III. Forming (Body Making)
Select proceaccording to product:
Slip Casting (Complex / Irregular shapes): Slurry enters plaster mold → absorbs moisture → pours excess slurry → dries → demolds → trachine Pressing / Dry Pressing (Tiles / Flat pieces): High-pressure molding of dry powder.
Throwing / Handmade (Art Ceramics / Round pieces): Hand throwing trimming (shaping).
Drying: Body dries naturally or in a dryer to moisture content < 3% to prevent cracking.
IV. Glazing and Decoration
Glazng: Dipping, spraying, pouring, etc.; glaze is uniform inside and out, thickness 0.3–1.2mm.
Decoration: Painting, decal transfer, carvig, printing, etc. (underglaze / overglaze).
V. Firing (Core Process)
Biscuit Firing (Optional): Low-temperature fring at 800–900°C to enhance body strength and reduce glaze firing deformation.
Glaze Firing / Final Firing: Enters kiln (tunnel kiln /shuttle kiln), high-temperature firing at 1150–1350°C; body vitrifies and glaze melts.
Cooling: Slow cooling to preventracking.
VI. Post-processing and Quality Inspection
Trimming / Polishing: Remove burrs, trim foot.
Grading Inspection: Appearance, dimensions, strength, water absorption, gaze quality, etc.; graded.
Repair / Scrap: Minor defects are repaired; severe defects are scrapped.
VII. Packaging, Warehousing, and Delivery
Standard packaging → warehousinng according to order → logistics tracking → customer sign-off.
