1. The concept of cookware coating line


The cookware coating line is a production line specially used for surface coating treatment of cookware. It includes a series of coating processes, such as surface pretreatment, spraying, drying, curing, etc., to ensure that the cookware has the required appearance and performance. The cookware coating line usually consists of pre-treatment equipment, sandblasting machine, coating equipment, paint supply system, drying equipment, conveying system, environmental protection equipment, etc. to ensure the quality and beauty of the cookware.

2. Process flow of cookware coating line


In cookware painting lines, surface treatment technology is crucial. This includes removing dirt, grease and other impurities from the cookware surface to provide the best possible finish for painting. In addition, some cookware may require special pre-treatment, such as phosphating or passivation, to improve its corrosion resistance.


Many cookware require the use of automatic sanding machines for internal and external sanding to enhance the adhesion of the coating. The automatic sanding machine without fixtures independently developed by Chuangzhi Coating has a small footprint and high production capacity. The production capacity of a single sanding machine can reach 1,300 pieces per hour, which can realize the mixed production of cookware workpieces with different product sizes.

Spraying technology is another key link in the cookware coating line. This includes the use of a variety of coatings such as varnishes, primers and specialty coatings to provide the desired color, shine and durability. During the spraying process, it is usually necessary to use professional spray guns and spray equipment to ensure uniform coating and the best appearance.


Next is the drying technique. The coated workpiece is transported to the curing furnace by the conveying system, and is cured by setting the curing temperature and time. The commonly used curing methods are natural gas or electric heating curing, dry air curing, etc. This ensures that the coating forms a hard, protective layer on the cookware while maintaining its original functionality and appearance. In addition, some cookware may require a special drying process to ensure that it does not deform or become damaged during use.

3. Application of cookware coating line


Cookware coating lines are widely used in the production of many types of cookware, mainly suitable for rice cooker liners, non-stick pans, frying pans, air fryers, cake pans, etc. Not only do these cookware need to be beautiful and durable, they also need to maintain their original functionality and practicality. Therefore, cookware coating lines need to take into account factors such as product design, materials and usage. In addition, as consumer demand for high-quality cookware increases, the cookware coating line is constantly being upgraded and improved to meet consumer demand.

4. Future development trends


As consumers' demand for beautiful, durable and environmentally friendly cookware increases, the development trend of cookware coating lines has become increasingly obvious. First of all, the development of environmentally friendly coatings and processes will help reduce the emission of harmful substances during the coating process and improve the environmental protection level of the production process.


Secondly, the application of intelligent and automated technologies will further improve production efficiency and quality, and reduce manual intervention and errors.


In addition, personalized customization will become an important trend in cookware spraying lines, and consumers can choose different colors, patterns and materials according to their own needs to meet different aesthetic and functional needs.
