5-Stage Quality Control in TangCai
01

Raw Material

Made with high-quality bread iron, our cast iron cookware ensures superior standard.

02

Automatic Molding

We utilize world-class DISA Automatic Production Lines (Denmark technology) to create the sand molds,This ensures Wall Thickness Consistency.

03

Melting and Pouring

Ensure the structural integrity of cast iron cookware.

04

Enamel & Seasoning Coating

For Enamel: We apply 3 layers of enamel coating and bake them at 800°C+.

For Pre-seasoned: We spray 100% natural vegetable oil and bake it to create a deep, non-stick coating. This creates a durable, rust-resistant finish. 

05

Lab Testing

Before packaging, we will do “thermal shock test”, ”flatness test”, “drop test”.

This can minimize returns and after-sales complaints.

06

Final Inspection before package

The last line of defense before the product is boxed.

Includes visual Inspection,flatness test,impact and stress testing etc,.
