AFS Tensile Strength Testing. AFS Tensile Testing –often called “Dogbone” Testing • Tensile strength of various sands (chromite, silica, olivine etc.) can be measured by mixing with a foundry resin system and preparing 1 inch thick (2.54 cm) tensile specimens or “Dogbones”. • The tensile specimens are prepared and allowed to cure for
For this reason, we manufacture and supply pure silica sand using the best techniques for our customers. We can manufacture different AFS as per the customers'' requirement. Key benefits of foundry sand are high level of permeability, better casting finish and 100% dry free from dust. Quartz sand for glass industry

The sand mixtures were transferred to the blow magazine of a No. 372-A-O Cold Box Tensile Curing Machine, utilizing a three gang AFS standard design dog bone core box. A second batch of sand was mixed and blown into a second core box that contained the AFS standard high temperature sample.
AGS and AFS. These values are calculated from the results obtained in Particle Size Analysis ( Section 3.2) and give a rapid indication of the average size of the sand particles. It is now more usual to refer to sieve size by aperture. However, the AFS number relates to and is calculated using the old BS mesh system, and effectively gives an
