The heating tubes normally cast or punched inside the cast aluminum heating plate are made of metal, and the main materials are iron, stainless steel, and imported materials. 1. Yes, 2. Cast aluminum heating plate inside casting or punching insertion needs to use metal heating tube, stainless steel heating tube and iron heating tube can be, the surface is not charged. 3. If the surface of the heating wire plate is used, it will be electrified. 4. The cast aluminum heating plate is normally used below 380 °C, and the aluminum plate will be deformed or even melted at a temperature above 400 degrees or even higher for a long time. 5. The surface temperature of the 304 stainless steel heating tube is about 450 degrees, and the surface temperature uniformity of the cast aluminum heating plate can be used and the tube arrangement, the flatness of the surface of the heating plate and the process heating of the heating tube are uniformly related.
