Process for compressing granular material in a molding box |
摘要 |
A process for compacting foundry molding material is proposed, the molding material being introduced into a molding device with a pattern plate with a pattern frame and a molding and filing frame mounted on it, by means of a compressed gas, the compressed gas being used at least for precompaction, the pressure surge used for the precompaction being released into the molding floor with a low, then a higher pressure gradient.
