Heat insulation strips of broken aluminum is also called broken aluminum, heat-insulating aluminum alloy, broken aluminum alloy. Heat insulation strips in our country to appear much later, about 2000 began to apply, but at present the development of China's heat insulation strips market is not too standardized, good and bad product quality flooded doors and windows market. Aluminum on both sides, the middle of the thermal bar plastic profile cavity to do the thermal break material. This innovative structural design, taking into account the advantages of both plastic and aluminum alloy materials, while meeting the decorative effect and the strength of doors and windows and old age-resistant performance of a variety of requirements.

A complete set of heat insulation strips extrusion mold, including an upper template, a casting runner plate, a convex mold fixing plate, a number of convex mold inserts, a concave mold assembly, a lower template, an ejector device, said concave mold assembly including a concave mold cavity body, a number of concave mold inserts, a concave mold insert fixing plate, two concave mold cavity side plates, a concave mold cavity body in a mouth-type structure, the upper part of the concave mold cavity body mounted with a concave mold insert fixing plate, the two sides of the concave mold cavity body respectively provided with a concave mold cavity side plate, and a concave mold cavity side plate. The concave mold cavity side panels, the concave mold insert fixing plate is provided with a concave mold step hole corresponding to the position of the convex mold insert, the concave mold insert is also provided with an insert step, and the concave mold insert is fixed in the concave mold step hole by the insert step, and the two concave mold cavity side panels are provided with a cooling water inlet and a cooling water outlet, respectively.

Heat insulation strips from the specific model of the product, the first three types of heat insulation strips enterprises can only produce most of the I-type, C-type and T-type conventional models, while the few fourth type of enterprise also mastered the multi-cavity type, blocking the arm type, super-width, thin-walled and other high-end thermal bar models of the production technology. With the improvement of people's living standards on the material requirements are also more and more elaborate, building windows and doors from the early single-glass wooden windows and doors, to single-glass solid-bellied steel windows, hollow-bellied steel windows, aluminum alloy windows and doors, plastic steel windows and doors, and finally evolved to the current broken-bridge aluminum windows and doors, aluminum-clad windows and doors and doors and a variety of energy-saving windows and doors coexist situation.
