Sand core machine application
What are sand cores used for?
Sand core is a material used to make cores in foundry production. It is made up of foundry sand, sand binders and auxiliary additives mixed in a certain proportion. The function of the sand core is to form the inner cavity of the casting, and it can also form the local shape of the casting. Sand cores require high strength, fire resistance, air permeability and toughness, and easy cleaning
Sand cores are mainly used to form inner holes and cavities of castings. Some shape parts that hinder the mold release and are not easy to produce sand can be formed by sand cores. The working conditions of the sand core are relatively poor, so the requirements for the sand core:
