as for heating coil and aluminum sheet, which one is better for heating?
Heating coil has a short lifetime, and aluminum sheet for heating can be used for a long time. Stainless steel heating tube is embedded into aluminum sheet for heating, because the heating coil isn’t exposed, it can be used for a long time.
Both of them have advantage. It depends on the new product type it’s applied. Heating coil: it’s applied in some products with high temperature and large heat release, such as oven and other types.
