Impact of the permeability of the molding sand on the height of the sand mold during Molding

Impact of the permeability of the “Molding sand” on the height of the “Sand mold” during Molding
During the “Molding process” of the “Automatic molding machine”, the permeability of the “Molding sand” has the following main effects on the height of the “Sand mold”:
1. When the permeability of the “Molding sand” is good:
It may make it easier for the gas to be discharged during the “Compaction process” of the “Molding sand”, and the “Molding sand” can be more evenly distributed and compacted, which helps to maintain the relative stability of the “Sand mold height” and reduce the impact of local unevenness caused by gas accumulation on the height.
2. When the permeability of the “Molding sand” is poor:
During the “Compaction process”, gas is not easily discharged, which may cause “Local swelling or Compaction”, resulting in uneven or locally “High or Low” “Sand mold height”, affecting the consistency and accuracy of “Sand mold height”.
Meanwhile, “Poor air permeability” may also affect the overall strength and quality of the “Sand mold”, indirectly affecting the control of “Sand mold height”.
3. However, generally speaking, the permeability of the “Molding sand” mainly affects other aspects of “Sand mold” quality, and the direct impact on the height of sand molds is relatively small. It mainly indirectly affects the height through factors such as compaction effect.
