Lost foam casting process

Like other casting processes, lost foam casting has its drawbacks and limitations, and not all castings are suitable for production using the lost foam process. Specific analysis is needed. Consider whether to adopt this process mainly based on the following factors. The larger the batch size of castings, the more significant the economic benefits. The order of good or poor applicability of casting materials is roughly as follows: gray cast iron - non-ferrous alloy - ordinary carbon steel - ductile iron - low carbon steel and alloy steel; By preparing to avoid excessively long process experiments and debugging cycles. 3. The size of castings mainly depends on the usage range of the corresponding equipment (such as vibration table, sand box). 4. The more complex the casting structure, the more it can reflect the feasibility and economic benefits of the lost foam casting process. For situations where there are narrow internal channels and interlayers in the structure, experiments are required before using the lost foam casting process for production.
