As head of production at the leading Chinese cookware factory, I’m eager to share our process. Our advanced setup uses state-of-the-art equipment for efficient, precise cookware creation. Each production phase utilizes specialized machinery and skilled labor.
As the premier manufacturer of cast iron cookware, we at KÖBACH understand the critical role production plays. Our advanced process ensures superior quality products, boosting our clients’ brand reputation. By addressing their challenges around quality and consistency, we drive customer satisfaction and business growth.
The primary raw materials for cast iron cookware are pig iron, steel scrap, and various alloys. These materials are carefully inspected and sorted to ensure their quality.
The raw materials are melted in a furnace at high temperatures to create a molten mixture. This is usually done in a cupola or electric induction furnace.
The molten iron is poured into a mold, which has been prepared with a cavity in the shape of the desired cookware. The mold is typically made from sand, clay, and other binding materials.
After the iron has cooled and solidified, the mold is carefully removed, revealing the rough casting of the cookware.
The cast iron cookware is cleaned to remove any residual sand and impurities. Excess material and rough edges are removed through a rough grinding process.
At this stage, the cookware has been shaped and polished but has not yet received its final coating or treatment.
A base layer of enamel is applied to the cookware. This serves as a protective coating and provides a base for the colored ceramic/enamel that will be applied later.
The colored ceramic/enamel coating is sprayed onto the cookware, giving it a distinctive appearance and providing additional protection.
Any excess ceramic/enamel is removed, and the surface is smoothed to ensure a consistent, high-quality finish.
The cookware is placed in a high-temperature kiln to set the enamel and give the cookware its final shape. This step also helps improve the durability and overall quality of the cast iron cookware.
Clean the uncoated cast iron cookware thoroughly to remove any dust or debris. Once clean and dry, apply a thin layer of vegetable oil evenly across the entire surface, both inside and out. You can use a paper towel or a soft cloth to ensure the oil is spread uniformly.
Preheat your oven to about 450-500°F (232-260°C). Place the oiled cookware upside down on the middle oven rack, with a baking sheet or aluminum foil on the lower rack to catch any oil drippings. Bake the cookware for about an hour.
After the hour has passed, turn off the oven and allow the cookware to cool down completely inside the oven. The high heat bakes the oil into the cast iron, creating a non-stick, protective layer that becomes more robust with each use.
Once the cookware has cooled and the seasoning process is complete, inspect it for any uneven or missed spots. If necessary, you can repeat the seasoning process to ensure a consistent and smooth finish.
Automated packaging machines wrap, label, and box the cookware for shipment, providing consistent and efficient packaging to protect the finished products.
