In sand casting, a binder is used to make sand grains stick together to form molds and cores. The binder system affects the production rate, surface finish, and defect formation. 

Here are some casting binder technologies:
Binder jetting: A process that creates models by depositing a binding agent into a layer of powdered material. It's similar to an ink-jetting process and can produce high-definition 3D models when combined with finely granulated material. Binder jetting is used to make casting molds.
Furan molding: A technique that produces castings with a smooth surface, high precision, and fewer defects. It can be used to process large-volume parts, intricated shaped castings, and high precision required orders.
Enhanced investment casting binders: A polymer that speeds up processing time and reduces the number of coats required to produce a ceramic shell.
Silicate binders: Made from potassium silicate or sodium silicate, these binders have good refractory properties and can withstand high temperatures. They can be used with a variety of sand types and can be cured by drying or by adding an acid catalyst.
Geopolymers: Act as a binder to convert semi-solid waste into an adhesive solid. They can also immobilize hazardous wastes containing elements such as lead, mercury, and arsenic.
Silicic acid: A suspension of silica in an aqueous medium with a diameter of the SiO 2 particles in the range of 1–100 µm.
Sodium silicate modification: Used as a binder of the sand when doing sand casting of steel or iron. It allows the rapid production of a strong mold by passing CO2 through the mixture of sand and sodium silicate in the mold box.
