这种制造型板的方法,的确比目前所采用者简单,如操作得当,可以大大减少制造型板时最繁重的机钳加工手续。但图1中通压缩空气盖子上面的螺旋盖,似乎装得并不妥当。应该改用能迅速封闭盖子才好,又文内对出气方面也讲得很不够,因为石膏模透气性很差,出气孔必须注意适当的安排,否则就会发生大量气孔,或者型板的几个角上浇不到。这些问题希望各厂在试行时注意和改进。最后,竭诚希望制造型板的各厂,能把试行的具体结果告诉我们,以便研究推广.
This method of making stencils is indeed simpler than currently used and, if properly done, can greatly reduce the most troublesome machine-nose machining procedures used to make the stencil. But in Figure 1 through the compressed air cap screw cap above, it seems not properly installed. Should be switched to quickly close the lid was good, but also the article on the vent also speaks very not enough, because the gypsum mold is poorly breathable, vents must pay attention to proper arrangements, otherwise there will be a large number of stomata, or a few templates Less than a corner of the pouring. These problems hope that the plants will pay attention and improve their trial. Finally, we sincerely hope that the manufacturers of the stencil can tell us the specific results of the trial in order to promote research.
