From dip wet (slip) enamel lines for cast iron pots and pans to electrostatic powder enamel plants for steel bodies — vitreous enamel surfaces that withstand heat, corrosion and food contact, engineered for production volume.
Enamel is a glass layer fused to metal at approximately 780–850°C — not a paint. Cast iron pots and pans need this vitreous surface to withstand heat, corrosion, scratching and food contact. STRONG3000 engineers the application, automation and enamel firing furnace technology for both electrostatic powder enamel plants for steel bodies and wet (slip) enamel lines for cast parts.
From individual application equipment to complete turnkey lines, we tailor the process to every cookware part and production target.
In cookware, the substrate (decarburized steel or gray cast iron) determines the process: steel bodies are coated with electrostatic powder enamel, cast parts with wet (slip) enamel. Below we summarize how we approach each part; you can download technical datasheets (PDF) for the part-specific engineering/metallurgy approach.
Outgassing in deep-drawn steel can cause fish scale; decarburized steel and two-coat/one-fire powder enamel for a non-porous, acid-resistant interior.
