Manufacturing process of Christmas tree decorations and racks for their fixing during this process

Abstract

A method of manufacturing Christmas tree decorations, in which the glass semi-finished product (1) is first blown into the required size and shape, including the process handle. The glass semi-finished product is fixed to the rack and placed in the metal coating device, where a thin layer (1 to 7 microns) of metal and / or its alloys is applied in a vacuum using vacuum plating or vacuum powder coating methods is coated on the surface of the glass semi-finished product (1). The metal painted surfaces obtained in this way can be finished in various colors using luminous or matt transparent and colored paints. Before the glass semi-finished product is put into the vacuum metal coating device, the Christmas tree ornament glass semi-finished product (1) can be shielded at the location of the desired ornament. After the masking element is removed, a clean unpainted location is obtained on the decorative surface. When the above method is carried out, the shelf holding the glass semi-finished product of the decoration is placed in the metal painting device, the shelf comprising a plastic or metal trough (2), at least one flexible one with at least one cavity The shielding device (3) is placed in the slot (2). The flexible screening device (3) is fixed in the metal channel (2) by being supported between lugs on the sides of the channel (2). The groove (2) has two side rotating shafts (6) for placement in the radial bearings, which are arranged on the opposite sides along the periphery of the working rotation of the vacuum metal coating device.

Description

technical field [0001] The present invention relates to a Christmas tree ornament, in particular to a method of manufacturing a Christmas tree ornament with decorations in a vacuum process and a stand for fixing the Christmas tree ornament. Background technique [0002] At present, the production of Christmas tree decorations is to blow out semi-finished glass products including craft handles according to the required size and shape by hand or by machine. The semi-finished product then remains transparent or is further colored and decorated (installing an ornament), or silvered in a simultaneous coloring and decoration operation. [0003] The principle of the silver plating operation is to apply a thin layer of silver to the inner surface of the glass semi-finished product. For this purpose, complex solutions of silver nitrate are reduced using sodium tartrate or other reducing agents. The disadvantage of this method is the use of ammonia to convert the silver nitrate into...
