DESC:The principle object of this invention is to ensure minimal surface contacts of a set of metallic tie-rods (1) operated in plurality during the electro-chemical process of anodisation. The tie-rods (1) are to be suspended in an electrolytic bath tank (200) by maintaining minimal but firm surface contact between the tie-rods (1) under suspension and the suspension media (100) itself.
Another object of this invention is to ensure better circulation of electrolytic solvent around the surfaces of the tie-rods (1) by using a suspension media (100). To allow proper swinging/moving of the tie-rods (1) inside the electrolytic bath tank (200) it is required to maintain suspension media (100) flexible enough to allow movements and at the same time strong enough not to break under the induced loads of the suspended set of tie-rods (1). Also, the material of suspension media (100) is selected to have reasonable resistance to the electro-chemical process being performed on the tie-rods (1).
Another object of the invention is to provide forced convection of electrolytic solution near intricate features like threaded holes (1a) of tie-rods (1), to avoid the air-gaps, by means of a motorized agitator mechanism (300). Also, additional features like stirrer fans (204) and vent tubes (203) for compressed air circulation are incorporated inside the electrolytic tank bath (200) to provide alternate forms of forced convection for better agitation of the electrolyte during the process.
Further object of the invention is to design a special twister tool (101a) which is rotated by means of a pneumatic gun for inter-twining the long and thin titanium metallic wires in a specific pattern which further are used as flexible suspension media (100).
The above mentioned systems altogether are termed as the subject invention Flexible Suspension Media with Agitator Mechanism (FSAM), features of which are detailed in subsequent pages.
