FULL DESCRIPTION

The Electronic Universal Sand Strength Machine determines the strength properties of clay and/or chemically bonded foundry sand specimens. This strength machine applies pressure on a sand specimen until failure to calculate the maximum force needed to break the specimen and then digitally displays the test results. This advanced electronic technology is capable of running over ten different sand strength tests.  These tests include:

• Green and dry compression strength*
• Green and dry shear strength*
• Splitting strength
• Green deformation at maximum strength
• High compression strength
• Hot shell tensile strength
• Cold shell tensile and transverse strengths
• Disc transverse strength
• Core tensile and transverse strengths
• Hot box tensile strength

*The accessories required to test green and dry compression strength and shear strength of clay bonded foundry molding sand are included with this strength machine.  Additional accessories can be acquired separately to run supplementary tests.

To operate the Electronic Sand Strength Machine, the sand specimen is placed in the strength accessory.  The operator only needs to choose the correct test option then press the start button.  The self-starting arm applies pressure on a sand specimen until failure. (Applies to certain tests.  See below.)  After the maximum force is reached the device automatically resets the moving clamp arm to home position. The five-digit digital display shows the strength value of the molding sand specimen.  Digital calibration can be completed in minutes when using the Mechanical Load Cell (Model 42125).

When testing green compression and shear strengths, the device measures the force needed to reach the point of maximum strength without crushing the sand specimen.  This advanced feature is unlike older mechanical type strength machines which continue to apply load and measure sample resistance beyond maximum strength. By continuously sensing strength and automatically stopping load application at the exact point of maximum strength, the strength machine obtains much more accurate and repeatable results, using the Green Deformation Accessory (Model 42104E).

The ability to accurately measure green deformation without risk of destroying the sand specimen is another advantage of stopping the application of the load to the sand specimen at maximum strength.  By utilizing the Green Deformation Accessory (Model 42104E), deformation data can be obtained by tracking sand specimen length prior to starting the compression strength test and after reaching maximum strength at the completion of the strength test. Sand that is too brittle and that is subjective to broken molds, stickers, and trouble pulling deep pockets on difficult patterns may be caused by the lack of green deformation.

Components Included: Pneumatic Tubing (Approximately 1m (3′)), Pneumatic regulator/filter/lubricator, Pneumatic fitting (Connects pneumatic tubing to pneumatic regulator/filter/lubricator), Set green compression clamps, Set green shear clamps, and Adjustable clamp holder.
