It can work with powder and liquid paint.

It has a triple path polymerisation furnace.

Geinsa has recently started up an installation for painting gas bottles at the Zaragoza plant of Plaxair, an American multi-national company.

The line is comprised of an automatic shot-blasting machine, an automatic powder paint spray booth, with recovery cyclone and absolute cartridge filter with its relative application equipment, a polymerisation furnace, a paint spray booth with dry filters with their application equipment and overhead “step by step” transport chain.

The parts hang from a rotating hook and are put into the shot blasting machine, which is entirely made of anti-wear steel and suitable protected with barriers of the same long-lasting material.

Then, the bottles are taken to the booth where the powder is automatically applied by reciprocator. The excess powder paint is extracted in the base of the booth and taken to the cyclone, and then on to the absolute filter.

The powder enters the cyclone at a high speed, slowing down once inside, and the heavy particles are precipitated in the cyclone hopper and collected in a tank.

Heavy and fine particles

These heavy particles preserve the typical properties of the paint and are taken once again to the powder paint preparation area. The light or “fine” particles have lost their properties and go with the flow of air to the absolute filter to be removed by an agent.

Later on, the paint is polymerised in the furnace at 200ºC. The polymerisation furnace has triple path and is closed by automatic sliding doors that operate between one step and another. The heating is provided by direct flame / air stream natural gas burner.

The line also has a liquid paint spray booth with its application equipment for painting warheads. The excess paint is retained by high efficiency “V” filtering, with the characteristic that the pigment entering the filter at a high speed, slows down, producing a similar effect to the one that occurs in the aforementioned recovery cyclone.

With respect to the maintenance system, the transport chain includes hooks with specific lock to prevent splashes of shot-blast insofar as possible, and hook turning gear for the booths. The installation is controlled from an electrical cabinet with programmable robot and touch screen to facilitate the line management and control.
