Metalstar Prototype vitreous enameling factory is located in Foshan city, China. Foshan City is the well-known area offering highest grade vitreous enamel service in China. Benefited from the regional advantage and cooperated with our contracted subcontractors, we are able to deliver high quality enameling coated prototype in variety of colors, and the part size can go up to 39.0 inches * 43.0 inches(length* width).
For prototype parts required to apply vitreous enamel coating(including deep drawn sheet metal prototype), the carbon content of steel raw material must be strictly controlled to prevent unwanted reactions at the firing temperatures. Thus, the correct raw material selection is very important at the very beginning. Then, for all coming fabricating processes or methods, they also must be well planned and managed to get final high quality enameling coated parts. For example, the welded area is quite sensitive to enameling quality, so need to avoid welding or strictly controlling welding area and welding technology.
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1, 380 and 1, 560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating on metal, or on glass or ceramics. Vitreous enamel can be applied to most metals.
