<P>flash 飞边</P>
<P>burr 毛刺</P>
<P>in plastics, maybe same</P>
<P>but in casting it is not the same, burr is made by machine, flash is made by casting<br>sorry for the same message, please delete this one, thank you!</P>
<P>flash is meaning "飞边";</P>
<P>burr is meaning "毛刺";</P>
<P>Perhaps in plastics industry flash and burr is the same meaning, but in aluminium alloy casting industry is not the same, flash is made by casting, and burr is made by machine, so before machine we shall remove the flash and then after machine we deburr.</P>
