Squeeze test

The extrusion test usually uses a certain hardness of silica gel as the indenter, drives it with a cylinder, adjusts a certain pressure, imitates artificial repeated pressing, and measures the number of times to see the damage.

There is one RS-8500A mobile phone extrusion test machine in the Star Magnetic Laboratory, which is suitable for extrusion (hard pressure) testing of small electronic products to evaluate whether the structure is normal after N extrusions.
