水玻璃铸造厂选用开浇道根后粘浇道的举措DNl50法兰片构造，结构对称性、厚度匀称。如果直接在其上给出浇道，因浇道偏厚大，与蜡模本身产生厚度差，不只在从磨具取出环节中取蜡模艰难，而且还会因牙模型方法不合理导致变形；还会在蜡模的冷却环节中因厚度不均匀，而引起收拢变形。因此综上所述考虑到，对DNl50法兰片选用先预置浇道根(极度为1．0～1．5mm)，后粘浇道的方法去确保在蜡模上因浇道厚大而产生厚度不均匀，造成收拢不同步变形。
蜡模冷却方法：硅溶胶水玻璃铸造件压蜡后，需注意冷却方法的挑选，一般是空气中冷却将在凉水中冷却。在凉水中冷却可强制性蜡模定形，而有的三端或两边为法兰片，如DN40法兰闸阀体，在常规生产条件是放进储水箱中冷却的，以至于在蜡模里的两法兰片间隔L1和L2相距得非常大，可以达到2.0～2.5mm。
