The cold-spraying machine allows to automate the process of the busbar application onto the glass, decreasing the cost and labor required for it.
Using the same software that is used with the ULSP it is possible to calculate the busbar configuration and to start the application process.
The busbars can be of any shape, which might be of use in complicated projects for the achievement of the uniform temperature in all zones of the glass.
The glass with the applied busbars can undergo the process of lamination and bending.
The testing of the glass with the applied busbar has been conducted in one of the European laboratories, the result of this testing was positive and corresponded to the requirements of the European standards.
GDS applies the conductive busbars at the speed of 40 mm/sec. This allows to use the machine together with the ULSP without decreasing the overall heated glass production performance. The time required for the application of busbars is normally shorter than that required for the laser processing of the corresponding glass sheet.
The warranty period of GDS is normally two years (depending on the contract conditions).
Metal powder particles of a specified size are accelerated through a special process until they have a speed that is high enough for the application process. After that the stream of these particles is directed right onto the surface of the glass at a required angle, and this leads to the «sticking» of the particles to the glass surface in a shape of a metal strip. A small amount of particles due to various reasons may not stick to the glass and is evacuated with the aspiration system directly in the application zone so it won’t get into the environment.
Spraying system — a unique and patented spraying system for the application of the busbar onto the glass. It allows to apply the metal busbars onto the glass at a high speed and with a great precision. These busbars do not require any additional processing after the application — the wires can be soldered to the busbar straight away.
The work surface guarantees the glass does not get damaged, and provided the service and maintenance schedule is followed, it has a long-time resistance to laser radiation. The surface is equipped with an air cushion acting both as transport and a suction clamp when positioning, or loading/unloading. The air cushion serves for easy glass transport or positioning, while suction clamp holds the sheet providing accurate processing.
Aspiration system — patented and compact system for dust aspiration prevents metal dust from getting into the air in the working space. This allows using the machine under the normal working conditions of an average facility and installing it next door to the ULSP in order to create a production line.
