What processes are carried out in one place under the enamelware 'integrated production' mentioned in the description?
After seeing the description in the NODA HORO product guide stating it has Japan's only integrated production system, I became curious about which specific processes are handled directly in a single factory.
It is a method where the entire process—from pressing iron sheets to form the vessel shape, to applying glass glaze and firing it in a kiln—is completed in a single factory.
The base is solid iron, and the surface is smooth glass. Enamelware is a product made by baking and bonding a glassy glaze onto a metal body at high temperatures. Because it requires both metal forming skills to shape metal and glass skills to coat and kiln-fire the glaze, the manufacturing process is demanding.
NODA HORO is the only manufacturer in Japan that produces sheet steel enamelware through an in-house integrated production process covering all stages[1].
All processes are brought together in a single factory[2]. In a single factory located in Tochigi City, Tochigi Prefecture, NODA HORO carries out the entire process from pressing steel to shape vessels, to preparing glass powder, enamel coating, and the firing kiln process[3][4]. All parts, including handles and fittings, are also made in Japan[5].
hmmm, putting both metalworking and glass baking under one roof is close to a commitment to take full responsibility for quality from the start to the finish of a vessel.
The quantity of products manufactured daily at the Tochigi factory and the specific firing temperature of the kilns have not yet been confirmed.
