Generally speaking, the medium temperature wax is combined with the silica sol shell process, and the low temperature wax is combined with the water glass shell process! The shrinkage rate of medium temperature wax is higher than that of low temperature wax because the low temperature wax contains water vapor. If different, the size of medium temperature wax is more stable than low temperature wax, and the price is a little more expensive.




1. Silica sol shell making process adopts medium temperature wax precision casting, and low temperature wax generally adopts water glass shell making process.




2. Since low-temperature wax contains water vapor, the shrinkage of medium temperature wax in precision casting is larger than that of low-temperature wax.




3. Compared with low temperature wax, medium temperature wax precision casting has stable dimensions and is expensive.




4. Medium temperature wax precision casting wax treatment is different. Medium temperature wax is dehydration and purification treatment, and low temperature wax is a reaction to remove saponification.




Due to its characteristics, the application range of medium temperature wax precision casting is wider than that of low temperature wax, which is more suitable for casting users.
