7. Production Process
Raw Material Selection: High-purity zirconia powder from China and TOSOH (Japan) ensures high performance and consistency.
Mixing & Layering: Powder is mixed with stabilizers and colorants; optional multi-layering replicates natural tooth gradients.
Cold Isostatic Pressing: Ensures uniform density and high-strength blocks.
Pre-sintering: Removes residual stress and stabilizes the material.
High-Temperature Sintering: Sintered above 1200℃ for final densification and hardness.
Cooling & Processing: Natural cooling followed by optional trimming and grinding to meet specifications.
Quality Inspection: Strength, appearance, and dimensional accuracy are checked. ISO 13485, CE, and FDA certified.
Packaging & Shipping: Protective packaging with timely delivery (1–3 working days for standard products).
