Thermal Break - Knurling Machine

Used for knurling the inside of the profile groove in order to increase the slip resistance, this thermal break knurling machine has been designed for semi-automatic operation and quick setups.

Through the line three steps - open teeth, through the strip, rolling, this door and window people know.

 Simple three steps, is an important part of the profile to the door and window.

The quality of the composite profile is the first and most important link to do high standard doors and Windows (most manufacturers will ignore), because there is no high standard finished profiles (such as bending, warping, water leakage, no compression), no matter how high-precision imported equipment can not make a high standard of the whole window, and can not guarantee its performance.

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.
