It is used to determine the hot tensile strengh of the resin sand
and the coating sand. It can be used to determine the tensile
strengh in the normal temperature.
The hot tensile strength is one of the main detection methods for
judging the film-forming properties of resin sand and coated sand.
It is equipped with a microcomputer intelligent control stepper
motor loading system, intelligent automatic temperature control
system and intelligent measurement system. It adopts liquid crystal
display, high-precision load cell and miniature Chinese printer.
The sample is placed on the host sample mold, and automatically
heated (232 ° C, about 120 s), automatically loaded to display the
force process curve, measured its tensile strength, display
measurement results, storage and print reports.
