FIELD: processes and equipment for applying powder coating. SUBSTANCE: method comprises steps of preparing objects for applying powder coating by providing temporary holding of powder; then applying powder in the form of layer hold onto object until formation of coating layer onto surface of object due to melting powder and transforming it to solid state by setting. Powder is prepared in such a way that to provide its low melting and softening temperature values, mainly lower than 100C, preferably 60-100C. Powder includes initiating system designed for setting powder material by action of electromagnetic irradiation. Powder applied on object is heated until its melting temperature for forming sticky layer onto coated surfaces of object. Then received layer is subjected to action of irradiation for setting it and to form coating layer covering surfaces with applied powder. Apparatus for performing the method includes unit for heating surface of objects until temperature for softening powder, unit for applying powder onto object, unit for heating powder until its melting temperature and unit having irradiators for setting powder layer. EFFECT: possibility for applying powder coating onto heat-sensitive objects. 7 cl, 1 dwg
