Alkyd, Phenolic no bake (PNB), Urethane no bake (PUNB) and Alkaline Phenolic no bake (APNB) for binding sand particles for making moulds and cores in metal casting Industries. With growth of Foundry industry, several self-sets have been introduced periodically for making molds and.
plastic 3D printing, no-bake molding, and direct casting. The 3D printer uses a spool of plastic wire passing through a heated nozzle mounted on x-y drive to fabricate a plastic pattern layer by layer from its solid model. Using this pattern, a sand mold block is fabricated by chemically-bonded no-bake system. The direct casting unit is a computer-controlled table-top induction furnace with No bake casting is most widely accepted in indian foundries due to its excellent surface finish and dimensional stability. It is a self-setting binder and it has a lower work and strip times. Though the casting process is also known as process of uncertainty, in the present study, an attempt has been made to investigate the effect of Grain Fineness Number, Loss of Ignition, Potential of
