S.p.A. |
The main Trasmetal quality
in over 50 years of existence has always been that of searching for alternative
technical
solutions that allow the limits of machines and equipment for surface treatment
and finishing to be overcome.
It is therefore based on this philosophy that Trasmetal directed it efforts
towards a technical solution able to overcome the fiscal limits of traditional
electrostatic equipment.
 |
The basic idea was that
the Trasmetal electrostatic distributor was to have a fluidised tank
to which the powder would be transferred from a pump located on the
ground. This tank would allow the powder itself to be drawn, loaded
and delivered so as to eliminate any negative effect linked to the
variable distance of the distributor from the ground. This solution
would allow the lack of thickness homogeneity caused by the equipment
to be overcome, considering the high vertical travel. |
|
The distributor was
to be equipped with a large number of closely arranged electrodes,
and a continuous powder distribution slot that would avoid the effects
of discontinuous distribution along with the related interference
between the flakes of powder caused by traditional equipment. This
solution, by allowing continuous-flake powder emission, would have
allowed the lack of homogeneity on the horizontal axis to be overcome. |
|
The materials used,
the shape and the dimensions selected were to protect the distributor
from erosion caused by the abrasive effect of the powder; this would
allow preservation of the distributor characteristics over time,
minimising costs due to maintenance and spare parts. |
|
The amount of powder
distributed by each single distributor was to be comparable with that of over
a dozen traditional devices, with a consequent reduction of both
the variables that need to be managed to control the workpiece as
well as the maintenance operations of the line itself. |
