R. E. A.: 1291027 L’ATTIVITA’ L’attività della ATO s.r.l. consiste nella realizzazione di particolari a disegno in materiali plastici ottenuti da lavorazione meccanica per asportazione di truciolo. Consapevole della rapida evoluzione del mercato, la ATO s.r.l. ha da sempre rivolto la propria attenzione alle esigenze della clientela, ponendosi fin dall’inizio come principale obiettivo il successo dei clienti, per offrire un elevato livello qualitativo dei prodotti manufatti e soluzioni ottimali ed all’avanguardia, operando in stretta collaborazione con i principali produttori di semilavorati. L’EVOLUZIONE DELL’AZIENDA La ATO s.r.l. è stata fondata nel 1980 dal Sig. Spazzini con lo scopo di specializzarsi nella conoscenza delle proprietà dei tecnopolimeri e sui loro processi e tecniche di lavorazione. Nel 1986 viene installata la prima macchina utensile a controllo numerico. Questa scelta tecnologica, determinata dalla ferma intenzione di soddisfare sempre meglio le aspettative dei clienti, rappresenta una svolta decisiva nella politica aziendale della ATO s.r.l., che ora si pone come obiettivo la ripetibilità nel tempo della qualità e precisione dei prodotti manufatti. Negli anni successivi, per migliorare il servizio offerto ai clienti, viene sviluppato e potenziato il sistema informatico riuscendo nel 1992 a completare l’informatizzazione dell’intero processo produttivo degli 8 CNC. Nel 2000 viene inaugurato il nuovo stabilimento produttivo di circa 2000 mq. e viene installato il primo centro di tornitura e fresatura INTEGREX - 200Y della Y. MAZAK. L’anno successivo, la ATO s.r.l. ottiene la certificazione del proprio Sistema di Gestione Qualità secondo la norma UNI EN ISO 9002 edizione 94; a ottobre 2003 ottiene la certificazione secondo la norma UNI EN ISO 9001 edizione 2000. Attualmente la produzione utilizza per lavori di tornitura e fresatura un parco macchine utensili di 13 CNC.

Applications of MELDIN® 7000

Our MELDIN® 7021 self-lubricating polyimidematerials meet or exceed the most stringentrequirements for aerospace applications. Backed up by third-party independent testing, the MELDIN® 7021 material grade provides our customerswith consistent mechanical and performanceproperties for aircraft airframe systems such aslanding gear and fuselage components, as well as jetengine parts such as pads, bumpers, washers, seals,and bearings.

Semi-conductor manufacturing customers require processequipment whose materials have high purity, high resistanceto solvents, oils, and other process chemicals, and highelectrical insulative properties — all combined with theability to hold dimensional features over a wide temperaturerange. The MELDIN® 7001 unfilled resin grade fulfills allthese requirements. Available as finished machined parts, orin basic shapes (ask about our 12" x 12" plates), MELDIN®7001 will add value to your production.

MELDIN® 7001 materials are direct formed and machinedfor use in critical plasma cutting torches in the torchhandle. These torches create high energy vortex gasstreams, and MELDIN® 7000 parts distribute these gasesprecisely due to their inherent dimensional stability andmachinability. Also, other parts in the torch handleinsulate high electrical energy from the user, ensuringsafe operation. High impact resistance increases theuseful life of this equipment as compared to ceramicalternatives.

For the manufacturer of specialty glass containers,the process required a low friction, high temperatureresistant surface that would not cause cracking orvisual damage while the containers slid across thesurface. A unique hole pattern was developed toprovide a controlled cooling operation for thecontainers. MELDIN® 7022 was chosen due to itshigh geometric stability and ability to provide asmooth sliding surface without causing anydamage to the glass.

MELDIN® 7001 unfilled polyimide grade was used as athermal insulator in a hot runner nozzle for an injectionmolding machine. Designed especially for molding thehighest temperature materials, the hot runner nozzlerequired a tip that thermally insulated the molten plasticfrom the nozzle housing while preventing a color transfer ofthe molten plastic onto the nozzle tip. This allowed the userto quickly change the resin colors without having todisassemble and change the nozzle.

MELDIN® 7211 is used in critical hydraulic and hotgas piston ring applications because of its hightemperature resistance and low friction, particularlyagainst soft metals like aluminum and stainlesssteel. In addition, the custom piston ring overlapdesign minimized leakage and improved overallefficiency of this self-lubricating ring seal.
