Hirays technology has customized a mold for its walkie talkie. Put the back of the walkie talkie up into the mold, and the whole shape is just right. When testing, the upper and lower molds will be closed to form a closed space around, and the instrument will fill the mold with impurity free gas through the tube, In this way, the air tightness of the walkie talkie can be judged by the air saturation inside the mold.
