Casting characteristics of Lost Foam Process
1. Flexible design
It provides sufficient freedom for casting structure design. Highly complex castings can be cast using a combination of foam dies.
2. Reduce investment and production costs
Reduce the weight of casting blank, machining allowance is small.
3. No sand core in traditional casting
Therefore, there will be no uneven casting wall thickness due to inaccurate sand core size or inaccurate core position in traditional sand casting.
4. High casting accuracy
Lost mold casting is a new process of near zero margin and precise molding, which does not require mold taking, parting surface and sand core, so the casting has no flash, burr and die inclination, and reduces the dimensional error caused by the core combination.
5. Clean production
There is no chemical binder in the molding sand, the foam is harmless to the environment at low temperature, and the recovery rate of the old sand is more than 95%.
Lost mold casting equipment process and other casting processes, there are its shortcomings and limitations, not all castings are suitable for the use of lost mold process to produce, to carry out specific analysis.
