Enamel is an excellent material with extremely high corrosion resistance, wear resistance and high temperature resistance. It is widely used in various fields, such as kitchen utensils, sanitary ware, chemical equipment, etc. With the continuous development of science and technology, more and more emerging industries are beginning to use enamel materials, including the automotive industry.

Recently, an automobile manufacturer contacted Nolifrit. Some automobile parts want to be made into enamel. However, this automobile part uses ductile iron material to ensure the toughness and strength of the product itself. As we know, ductile iron is made of enamel. Enamel can easily produce pinholes and bubbles, which makes the manufacturing process very difficult. Prior to this, car manufacturers cooperated with multiple enamel factories, but none of them solved this problem.

After receiving the sample, Noli's technicians used cast iron pre-ground powder to proof it. The sample adhered well and did not produce defects such as pinholes and bubbles. The customer was very satisfied with the proofing result and is currently negotiating for follow-up cooperation.

What is cast iron enamel pre-ground powder?

Cast iron enamel pre-ground powder is ground from special enamel frit or a certain proportion of enamel frit, clay, and grinding materials, and is suitable for cast iron enamel. When making enameled ductile iron parts, the ductile iron needs to be sandblasted first, then the cast iron pre-ground powder is added to water and evenly stirred into a enamel slurry, which is evenly coated on the surface of the ductile iron, dried and fired.

Using cast iron pre-ground powder for proofing can effectively avoid the occurrence of quality problems such as pinholes and bubbles, ensuring the quality and performance of enameled ductile iron parts. At the same time, cast iron pre-ground powder also has anti-rust and anti-corrosion effects, which can extend the service life of enameled ductile iron parts.

The use of Noli cast iron pre-grinding powder is an effective way to solve the manufacturing problems of enameled ductile iron. It can improve the quality and performance of enameled ductile iron parts and meet the high requirements of the automotive industry for materials. Nolifrit will continue to be committed to researching and developing advanced enamel technology to provide better products and services to various industries.
