Ultrasion Sells the first machine of moldeo by ultrasounds in EE UU
During the past edition of the fair K'2013 the company
The machine purchased by Oratech is allocated to a confidential application of the medical sector, more in concrete to the manufacture of tips dosificadores extra-long, “impossible to manufacture to date with the technology of the conventional injection” as it affirms Enric Sirera, Commercial Director of Ultrasion. The thicknesses of wall of the quoted tips dosificadores are of 0,075mm along 15mm of route of flow.
The machine Sonorus1G has made possible the feasibility of the process deleting besides an enormous problem of break of noyos extremely long and fine that the high pressesure of the process of conventional injection has not been able to resolve to date of today. The process of moldeo by ultrasounds, in which it uses only and exclusively the proportionate power by a cabezal ultrasonic, without resistances, without husillos and without cameras of pre-plastification, opens a sinfín of possibilities in the manufacture of complex components.
The technology
The moldeo of micropiezas with ultrasounds pretends “to mark a full stop”. For the first time, they delete the traditional systems of thermal sensors warming to substitute them by the application of ultrasounds, mechanical waves of high frequency that agitate the molecules of the polymer of way faster that his own time of relaxation, which translates in a warming of the matter. This warming allows to diminish the viscosity of the material to such an extent that the material can flow to the cavities of a mould with pressesures very low and in time very reduced. This technology avoids some of the limitations that present the technologies of moldeo traditional, like the sobremoldeo of sensitive components to the pressesure, the degradation of materials because of high time of residence or the waste of material by purge of husillo, change of colour or stopped of machine. Between his advantages stands out the precision in the replication of micro cavities with thin walls and with details of high precision, an energetic consumption extremely reduced and the prevention of the degradation of sensitive materials through a very precise control of the window of process. The technology translates in an industrial machine of vertical presses totally electrical and silent with an apt size for the industry.
As it has been able to know Universal plastics / Interempresas, responsible of Technology of Oratech have valued the robustness, precision, and especially, the capacity of the machine to manufacture the considered impossible to date. “It opens a world of possibilities that had not been able to resolve until discovering this new technology” has signalled his Chief Tehnologist.
Ultrasion Attended to the K like debutante and received the visit of more than 300 visitors, impressesed all they by the character rompedor and innovative of the technology, allocated to potentially revolutionise the world of the manufacture of complex components inside the market of piece mini/micro. Sirera Shows very satisfied with the result of the fair: “A lot of people, from manufacturers of components, going through departments of development and technology centres until the own technological providers and competition has congratulated us for contributing perhaps the newest of the fair”.
