While the initial setup costs for investment casting can be higher than those for other casting methods, the long-term benefits often justify the investment. The process minimizes material waste, as excess metal is typically recycled. Furthermore, because investment casting produces parts with superior surface finishes, secondary operations (like machining) are often reduced or eliminated entirely. This efficiency translates to lower overall production costs, particularly in large-scale manufacturing.

Conclusion

Any setting or unreasonable operation of any link will change the shrinkage rate of the casting, resulting in The dimensional accuracy of castings deviates from the requirements. The following are the factors that can cause defects in the dimensional accuracy of precision castings:

The primary material in sand casting is, unsurprisingly, sand itself. The most commonly used sand is silica sand, due to its excellent thermal stability and ability to retain shape. Silica sand particles are usually angular or sub-angular, which enhances the strength of the mold. Another type of sand occasionally used is olivine sand, which contains magnesium iron silicate and is prized for its high melting point and minimal expansion. When selecting sand, it's essential to consider its grain size, shape, and cleanliness, as these factors directly affect the mold’s permeability and surface finish.
