Ní féidir an teip ar an mbás brionnaithe mar a thugtar air a dheisiú chun a fheidhm úsáide damáiste a athbhunú, is é sin, de bharr an damáiste nó an scrap den bhás a tharla go coitianta. Because plays a forming die chamber of the function of the forgings, it directly in contact with the hot billet, bear the function of impulse type heat load, and forging equipment applied under high energy impact load and blank metal flow scouring and embellish the role of the slip agent and other environmental media, in the mold of metallurgy and processing quality specification and normal operating conditions, forging die of damaged or destroyed Most occurred in the die chamber, therefore, the failure Is é an bás a bhaineann le bás a bhrionnú den chuid is mó nach féidir le comhad an tseomra múnla anois an modh a dheisiú chun táirgeadh cumais cáilithe a chur ar ais.
