1. Meltdown
Cast iron is made by melting a mixture of iron ore and coke at around 1400°C.
2. Shapes
The so-called aluminium mother mould is the tool that creates a sand mould for each individual product.
3. Watering
The molten iron is poured through a small opening in the sand mould. The sand moulds stand in a row vertically one behind the other.
4. Kick out
Once the casting is complete, the sand moulds are broken open and the products are knocked out. They are sorted and separated from the sprue.
5. Cleaning blasts
The products are blasted with small metal particles to remove the sand.
6. Deburring
Burrs (unevenness) at the mould joint are removed using a grinder.
7. Shot blasting
The products are cleaned with a shot blasting machine, then minor imperfections are removed manually. Shot peening with small metal particles creates the roughness necessary for the single-layer enamel to adhere to the raw product.
8a. Single layer enamelling
A first layer of enamel is applied to the entire product. This layer is intended to ensure that the following layers of enamel adhere permanently to the cast iron. The product is dried and then fired in the oven.
8b. Colour Enamel
The coloured enamel is sprayed on in liquid form using compressed air spray guns. Depending on the desired colour effect, this process is repeated several times.
9. Burning
After drying, the products are fired in the oven. The enamel hardens, becomes smooth and adheres perfectly to the product.
10. Packaging
Every product is tested according to a strict quality catalogue. Only then is it ready for packaging. Together with care instructions recipe ideas and, if necessary, accessories, the items are now ready for sale.
