Heating plate for hair straightening iron and its manufacturing process

Abstract

The heating plate for hair straightening iron and its manufacturing process consists of a case comprising two laminates made of insulating ceramic material; one of them holds a band made of electrical conductor material with outer connections, while one of the laminates has a surface coated with a polished layer of material; the case of the heating plate has features to adapt to the base structure of the iron. The manufacturing process of the heating plate for hair straightening iron is developed following these stages: 1) Preparation of the ceramic powder which comprises the milling of dispersants and adding of solvents, the mixing with the binding agent and adding of plasticizer; a viscosity control of the result is made, and then 2) there follows the moulding and corresponding drying; 3) the plates are cut and the resistor is screen printed; 4) the whole is laminated by pressure and then cut; 5) after that the binding agent is burnt and a sintering is performed; it is finished with 6) the welding of the contact terminals, and an eventual polished layer for coating purposes.
