From February 21st to 22nd, 2022, Nolifrit organized employees to study the proofing of enameled cast iron color pots, requiring every business person to observe and learn the proofing process of enameled cast iron gradient color pots under the guidance of professional and technical personnel and practical.

Enamelled cast iron pot is a common product in cast iron enamel. Learning this process will help Noli sales staff to understand the enamel technology in detail and serve every customer with a more professional attitude and professional skills.

In the pretreatment part of cast iron, annealing at 850 °C is done first to remove impurities and gases in the green body to reduce the generation of enamel defects, and then sandblasting is performed. In the preparation of enamel base glaze and enamel top glaze, cast iron white base glaze is selected for the base glaze, and purple cadmium red pigment and Nuoli special enamel pigment are added for the top glaze to make a two-color gradient appearance. Spraying is the difficult part of the whole process, because to achieve a gradient effect, you need to master skilled skills. The finished product is obtained after drying, firing and cooling after enameling.

The proofing process of enamelled cast iron pots is complicated, but Nuoli employees have devoted themselves to learning and meticulously completed each step, and finally got a satisfactory learning effect. Professional in diligence, Hunan Nuoli has always adhered to independent innovation and product differentiation, providing high-quality products and one-stop services to global customers.
