4、产品填充时间为2.884s,填充较平衡。Fill time is2.884s,and its balanced.,9,Fill time,Fill time(contour),无滞留痕和短射现象Theres no hesitation mark and short shot phenomenon in filling phase.,10,Weld Lines,Weld Lines Location,产品表面无明显熔接线,11,Air Traps,Air Traps Location,COMMENT:The areas highlighted in pink are the places whe
5、re air traps maybe happen.When designing a mold,these areas should be paid more attention as possible.An air trap will cause a burn mark if the air is under enough pressure,causing the air to ignite and burn the plastics.If an air trap is not vented,and it is not compressed fast enough to cause a bu
6、rn mark,it may cause a short shot,or leave bubbles of air or gas in the part.Even if an air trap does not cause a burn mark or short shot,it can still leave a surface blemish on the part.,气穴产生处，应当开排气，否则轻则出现短射，重则会烧焦产品We should make gas venting where air traps locate,otherwise it will appear short sho
7、t phenomenon or even burn product.,12,Pressure at V/P switchover,The V/P switchover time is at 2.85s,when the part volume is filled at 99%The V/P pressure is 58.29MPa.It is suitable for molding.,Pressure distribution,13,Pressure at the end of fill,Pressure at the end of fill,COMMENT:The difference b
8、etween max.and min.value in the press distribution on the part is about 60Mpa.,如图所示，填充末端压力分布均匀As picture shown,the distribution of the pressure at end of fill is uniform.,14,Flow Front Temp,Flow Front Temp picture,由图可知，产品表面温度在16以内，分布均匀,表面质量好。As picture shown,the distinction of flow front temperature
