FIELD: personal use articles. ^ SUBSTANCE: door of domestic electrical appliance, in particular washing, washing-drying or drying machine with frontal load includes several structural elements of thermoplastic. At least two of specified elements are connected to each other by means of welding. Door comprises back part made of ABS-plastic and provided with a hole surrounded with circular surface. Door may include the first, the second, the third and the fourth parts. At least the first, the second and the third parts are made of thermoplastic material. The first part has at least one hole and surrounding circular surface, and the fourth part has at least one circular surface. Method of door manufacturing includes the following stages, where: a) the fourth part is positioned inside hole of the first part so that circular surface of the fourth part contacts with circular surface of the first part; b) the second part is positioned relative to the first part; c) the second part is connected to the first part by means of welding of linear vibration type, and at the same time the fourth part is placed between the second part and the first part; d) the third part is positioned relative to the first part; e) the third part is connected to the first part by means of welding, at the same time the second part and the fourth part are placed between the third and the first parts. ^ EFFECT: elimination of deforming stresses generated in process of door unit assembly. ^ 16 cl, 3 dwg |
