Environmentally friendly, non-silica formulated molding sand is delivered by a continuous loop system. Properties of the sand are monitored by Simpson fully automatic control system. If sand cores are required to make the casting they are made in either the Shell or Chemically Bonded Sand process to satisfy requirements.
When the pattern is removed, the cavity that will form the casting remains. Any internal features of the casting that cannot be formed by the pattern are formed by separate cores which are made of sand prior to the formation of the mold. Further details on mold-making will be described in the next section. The mold-making.
US4097443A - Method for manufacturing foundry molds - Google .
The binders which have heretofore been used practically in the manufacture of self-curing foundry molds and cores are roughly classified into inorganic binders such as gypsum, cement sodium silicate, etc., and organic binders such as drying oils and cold setting resins and so forth. Gypsum and cement are inexpensive,.

commercial and traditional core making processes are still being in use for principal normal production of cylinder heads and blocks. These processes include furanic hot-box process, phenolic isocyanate-urethane cold-box process and phenolic shell-moulding processes. All of them show excellent performance for core.
In this process, molten metal is poured into a disposable mold formed out of foundry sand containing binder. The cavity in the sand is . Core boxes, which are used for sand cores production, are second tooling in sand casting. . LOM is the most common application used for pattern making for very large casting sizes.
