Correctional checking formula of melt flow ratio in injection molding was obtained by introducing a correction coefficient β which reflected the complexity degree of mold cavity. The results show that, the maximum flow ratio of 486 can be obtained when injection pressure ranges from 150 MPa to 160 MPa in Archimedes spiral mold for PP, while maximum flow ratio of 419 can be obtained when injection pressure ranges from 160 MPa to 170 MPa for PE. There is a local fluctuation phenomenon for flow ratio and corresponding injection rate in square spiral mold when injection pressure of 100, 120 and 150 MPa for PP and 130, 140 MPa for PE are reached respectively,and this phenomenon is more serious for good fluidity of melt. The average flow ratio in Archimedes spiral mold is 6% larger than that in square spiral mold for PP, and 4% for PE, the average flow ratio of PP is 19% bigger than PE in Archimedes spiral mold, and 15% in square spiral mold. The influence of the cavity profiles on the melt flow ratio is more significant for good fluidity of melt.

研究结果表明：在阿基米德螺旋线模具中，PP在注射压力为150~160 MPa时取得最大流动比485，PE在注射压力为160~170 MPa时取得最大流动比419；在方形螺旋线模具中，PP在注射压力为100，120和150 MPa，PE在注射压力为130和140 MPa时流动比及所对应的注射速率出现波动，且流动性好的熔体波动更为严重；PP在阿基米德螺旋线模具中的流动比均值较其在方形螺旋线模具中大6%，而PE大4%；在阿基米德螺旋线模具中流动比均值PP比PE的流动比均值大19%，而在方形螺旋线模具中PP的流动比均值比PE的大15%；流动性好的熔体受模具型腔轮廓特征影响大。

The micro mold after forming of electroform needs the increasing thickness process which inset in the block and supports the micro mold during the injection modeling. Otherwise, the buffer layers could prevent the problems of stresss and surface deterioration.

然而微模具在电铸成形后需经增厚处理，因为增厚处理使非常薄的微模具与模具基座较易配合，也将提供微模具於射出成形过程中之支撑，一般增厚制程会在微模具与增厚层间加入一缓冲层避免应力与表层变质造成之问题。

By designing the mould to change the propellants model frame, selecting differentmaterials as propellant seal layer agents, studying the preparation technics, we havepreferably solved the PSS seal layer pressurize and combustion disciplinarian problem, andobtained the remarkable increasing burning surface effect.The practical increment ofΓvalue reachs 3.2 upwards conducting closed bomb firings, comparing with 19 holepropellants—the best progressivity burning in the present, whose practical increment ofΓvalue is 1.2, the PSS amplitude ofΓvalue exceeds 2.5 times.

通过药型结构和模具的设计、端面密封材料的选择和制备工艺的研究，较好地解决了PSS发射药的端面密封和燃烧规律控制问题，获得了显著的增面性燃烧效果，密闭爆发器实验中燃气生成猛度的实际增量达到了3.2以上，与目前增面性最好的19孔发射药实际增量的1.2左右相比，增幅超过了2.5倍。

Finally, several sets of cast dies and molds, including V6 transfer mold emplyed by GM, shoe die and piston die used for Santana, have been casted by LS high precise die-making system. All of these dies only needed a little machinaity. The cost and manufacture period of cast dies are lower than those of traditional wrought dies.

The helmet was then molded using the plaster head as a molding ground knowing full well that it would then fit back onto the mask. Once the plasterers had molded the mask and helmet, they were actually cast out in fiberglass with color in the resin so they were black, then maybe they were painted as well.

石膏面具的头部就等於模具的底部，这样制作出的头盔戴上实际完成的面具时就能完全吻合，石膏师在黏土完成的面具和头盔取模后，就能以石膏模来生产玻璃纤维的成品，玻璃纤维内含染色的树脂所以看起来会是黑的，不过他们之后可能还会再上漆。
