The old rule for new/core sand additions is 300 lbs. per ton of metal poured, but that approach needs to be re-evaluated ? and made more exact ? for current molding methods and materials. Foundry Questions and Answers – Green Sand Moulding -… Answer: b Explanation: In foundry processes, the sands are called green due to the moisture content in them. The moisture content makes the sand wet which is suitable for the molding. The moisture content varies according to the type of casting to be made. (PDF) Using Foundry Sand in Green Infrastructure… Foundry sand is a high-quality uniform silica sand that is used to make molds and cores for ferrous and nonferrous metal castings.Use of foundry sand as a fine aggregate in construction applications offers project managers the ability to enhance green sustainable construction by reducing their... GREEN SAND PREPARATION (Manufacturing Lab /Foundry)
With highly experienced foundry design engineers (averaging some 30 years in the industry), and our familiarity with every aspect of the metal casting process, we augment our domestic resources with extensive worldwide consulting engineering affiliates. We do not manufacture equipment. Our professional services are, therefore, unbiased.
Unfortunately, recognizing casting defects is one of the most challenging burdens confronting metalcasters. The good news is there is an answer for every defect. Imagine having the right sand testing equipment instrumentation in your laboratory to give you the analysis you need to better control your materials and processes to reduce defects.

UG-Mat Foundry Sand | Recycled Materials Resource Center Green sand consists of high-quality silica sand, about 5-10 percent bentonite clay (as the binder), 2 to 5 percent water and about 5 percent sea coal (a carbonaceous mold additive to improve casting finish). (2) The term "green sand" is used because molten metal is poured into the mold when the sand is damp or "green". Probable Causes and Suggested Remedies of Various Casting Defects Probable causes and suggested remedies of various casting defects such as blow holes, shrinkage, porosity, misruns, hot tears, mental penetration, cold shuts, cuts and washes, inclusions, fusion, drops, shot metal, shift, crushes, rat-tails, swells, hard spot, run out, fins and fash, spongings and warpage are given in the below table.
