Thermal break profiles use the aluminum profiles and also thermoplastic mixed material strip to combine.
Firstly, make the normal aluminum profiles.
Secondly, use the knurling machine, and strip rolling pressing machine to make the aluminum profiles and plastic material combine together.
Thermal break profiles solve the fatal problem of aluminum profiles which rapid heat dissipation and not energy-saving.
There are three parts left and the right side is the aluminum, and the middle side the plastic material. Please check the below picture.
