From prototyping, spare parts production to agile industrial series production. With Universal Binder Jetting 3D printing technology, and the tool-less production of sand molds and cores for classic metal casting processes, we are opening up new horizons for the foundry industry.
If a foundry is reclaiming sand, residual binder contributes to Loss On Ignition (LOI) at the mold/metal interface. LOI values consistently above 2% (prior to adding new binder to the sand) may contribute to gas defects. New sand additions can be made to reduce LOI if a Core-making in the Foundry - Reliance Foundry Co. LtdGreen sand cores are made from standard damp molding-sand mixtures, and a binder, like dextrin. Cores of this type are very fragile and can be made with an arbor or interior wires to facilitate handling. Dry sand cores do not contain water. They are made from silica sand and a binder to harden the surface.

SAND RECLAMATION. A.D. SARKAR M.Eng., B.Sc., in Mould & Core Material for the Steel Foundry, 1967. Upon and after the entry of liquid steel, the mould interface heats up, and the temperature within the mould rises, parts removed from the interface having progressively lower temperatures. Timetemperature distribution for a heavy 10 ton casting is shown in Fig. 37. Mold Steel - Finkl SteelPlastic injection molding demands a lot from the tool steel core and cavities:machinability, polishability and texturing, ability to weld, high thermoconductivity, and good mechanical properties to name a few. The mold steel from Finkl has been designed with the machine shops and the injection molders in mind.
As far as the steel-foundry mould and core material is concerned, tridymite or cristobalite can only form at or near the metal-mould interface. The silica sand as used in the foundry is the low temperature quartz form and is found in many mineral deposits, in rocks such as Mould and Core Coatings foundrymaterial.net Hi-Point Location:Hi Point Metallurgical Industries, Shahabpura, Amritsar Rd, Batala:143505.Punjab India.

The basis grains used for steel-foundry mould and core materials are mainly quartz either in the form of silica sand or naturally bonded sands together with an amount of nonsiliceous materials, such as zircon, chromite, and olivine.
