Imbuto zizungurukaByagenewe inkoni zo gufatana mu buryo bw'imashini zikoreshwa mu gushushanya, biherutse gushyirwa mu bikorwa mu buryo bunini. Bikoresheje uburyo bwo gufatanya buzenguruka, ibiimbutoBijyanye n'imigozi ya D7-D22 igenamiterere hamwe n'umurambararo wa plate ya D70-D110mm. Imiterere y'ifata rizunguruka yorohereza gukora, hamwe n'uburyo bwo guhuza neza ukoresheje formwork panels byazamutseho 20% ugereranije n'ibisanzwe.imbuto. Bipima hagati ya 0.18kg na 0.82kg buri imwe, byorohereza abakora mu bwubatsi gushyiraho no gukuraho vuba.

Kugeza ubu, amaseti arenga 12.000 y'izi mbuto zakoreshejwe mu mishinga y'inyubako zakozwe mbere mu majyaruguru y'Ubushinwa. Mu bwubatsi bufatika, igishushanyo mbonera cyazo kizunguruka kigabanya igihe cyo gufatanya kuri buri gice cy'inyubako ku masegonda agera kuri 15. Insinga zidashobora kwangirika zishyigikira imikorere irenga 30 yo kongera gukoreshwa, bigabanya igipimo cyo gutakaza ibice mu gihe cyo gusenya inyubako ku kigero cya 8% kandi muri rusange byongera ubushobozi bwo guteranya inyubako ku kigero cya 13%.
