mold life मीनिंग इन हिंदी

When the process is used to cast steel or iron the mold life is extremely short.
Large differences in section thickness in the mold or casting can decrease mold life as well.
There are three main disadvantages : high tooling cost, limited to low-melting-point metals, and short mold life.
On the other hand, molds made from H13 tool steel may have a mold life several times greater.
The pouring temperature is dependent on the casting metal, but the higher the pouring temperature the shorter the mold life.
The mold life is dependent on four factors : the mold material, the pouring temperature, the mold temperature, and the mold configuration.
For lower melting point metals the mold life is longer but thermal fatigue and erosion usually limit the life to 10, 000 to 120, 000 cycles.
Archie Byron was a deputy sheriff and politician in Fulton County, Ga ., before becoming an artist who molds life-size works from sawdust, solvent and glue.
For example, a particular zinc alloy is typically cast between 775 and 800 �F, whereas it actually melts much lower around 500 �F . If the metal is introduced to the mold at a higher temperature ( in this case, above 800 �F ), it will start to wear the silicone down prematurely, greatly shortening the mold life.
