Ekspansyon idwolik: Li se sitou itilize nan envantè de epesè miray epesè miray ak mwens pase DN400. sa yo ti yo apwopriye pou fòme materyèl yo, tankou asye kabòn ki ba, ki ba alyaj asye ak Nerjaveèi asye ak relativman ba tandans tandans, ki gen ladan kèk materyèl metal ki pa FERROUS, tankou kwiv, aliminyòm, Titàn, elatriye.
