No-bake molds are expendable sand molds, similar to typical sand molds, except they also contain a quick-setting liquid resin and catalyst. Rather than being rammed, the molding sand is poured into the flask and held until the resin solidifies, which occurs at room temperature.
The only disadvantage with this is that after the catalyst is mixed in there is a short time to use the sand. A third way to produce room temperature cores is by shell molding. [4] The term no-bake sands can refer to either the cold-box process or air-set process. [4] [5]
Goldens' added a fourth molding line, a no-bake sand operation in 2000. The manual molding operation allows production of much larger castings than the Sinto cope and drag machine, and is primarily utilized for Goldens' power transmission operations. This consists primarily of sheaves, pulleys, and sprockets.
[1] [2] Once the sand is compacted, the mold is ready to be poured. Automatic pouring is commonly used in LFC, as the pouring process is significantly more critical than in conventional foundry practice. [citation needed] There is no bake-out phase, as for lost-wax. The melt is poured directly into the foam-filled mold, burning out the foam as ...

Sand casting is one of the earliest forms of casting practiced due to the simplicity of materials involved. It still remains one of the cheapest ways to cast metal because of that same simplicity. Other methods of casting, such as those using shell molds , boast higher quality of surface finish but have a higher cost.
