Abstract
A machine for metallization of three-dimensional objects of small sizes comprising a feeding device (2) to supply a succession of objects to be metallized (20), a metallizing device (3) comprising a main sputtering chamber (31) in a condition of permanent vacuum and a loading and unloading chamber (30) for a single object, which can be switched between a vacuum condition and an ambient-pressure condition and is operatively connected to the sputtering chamber (31), an unloading device (4) for the succession of metallized objects (21), which is operatively placed downstream of the metallizing device (3), and a painting station (10, 14) of the airless type and operatively disposed downstream of the feeding device (2) and upstream of the unloading device (4).
Claims15
A machine for metallization of three-dimensional objects of small sizes, comprising:
- a feeding device to supply a succession of objects to be metallized;
- a metallizing device comprising a main sputtering chamber in a condition of permanent vacuum for coating each object with a predetermined metallic layer, and a loading and unloading chamber for a single object, which can be switched between a vacuum condition and an ambient-pressure condition and is operatively associated with said main chamber;
- an unloading device for the succession of metalized objects, which is operatively placed downstream of the metallizing device;
- a painting station of the airless type and operatively disposed downstream of the feeding device and upstream of the unloading device.
A method for metallization of three-dimensional objects of small sizes, comprising the steps of:
- providing an orderly succession of objects to be metallized at a feeding device and feed them in a row to a metallizing device;
- introducing a single object to be metallized into a loading and unloading chamber of a metallizing device;
- pressurising the loading and unloading chamber and introducing the object to be metallized into a main sputtering chamber of the metallizing device;
- introducing the metallized object into the loading and unloading chamber and depressurizing the same;
- picking up the metallized object from the metallizing device and providing a succession of metallized object at an unloading device;
- painting the objects between the feeding station and unloading station, using a painting device of the airless type.
