Tooth cutting

The part of the aluminum profile that needs to wear the heat insulation strip is rolled out with the gear cutter, the purpose is to increase the roughness of the profile so as to improve the shear force of the composite profile, which is equivalent to a row of "teeth" biting the heat insulation strip.

Profile Assembling

Threading is to Pierce the heat insulation strip into the upper and lower aluminum notches that have been opened, so that the three are integrated.
