The thermal break aluminum profile insertion equipment is a specialized device for producing thermal break aluminum profiles. Its core working principle involves mechanically embedding the thermal break strip into the groove of the aluminum profile and achieving a tight bond, thus realizing the "thermal break" function of the aluminum profile. The specific principle can be explained by breaking down the processing steps:
Core Processing Principle (Mainstream Roller Embedding Process)
Currently, the industry commonly uses the "roller embedding" process, which is divided into three-step and two-step methods. The core principle is the same; only the process steps differ:
Gearing Process Principle: A high-speed rotating gear cutter rolls teeth (roughening) into the groove of the aluminum profile where the thermal break strip will be embedded. The purpose is to increase the lateral shear force between the groove and the thermal break strip, preventing the thermal break strip from falling off. The equipment uses the rotation of the gear cutter as power to directly pull the aluminum profile forward, completing the gearing process.
Strip Insertion Process Principle:After the teeth are cut, the automatic strip insertion mechanism of the equipment inserts the rigid PVC thermal insulation strip (or adhesive strip) into the pre-cut grooves in the aluminum profile. The integrated machine can complete the teeth cutting and strip insertion simultaneously, reducing manual labor and improving efficiency. Some machines can also be equipped with a polyurethane foam filling function, injecting foam material into the insulation cavity through nozzles to further enhance the insulation and sealing effect.
Rolling and Pressing Composite Process Principle: After the strip insertion is completed, the equipment uses multiple sets of roller presses to roll and press the profile with the inserted thermal insulation strip, tightly pressing the aluminum profile and thermal insulation strip together to ensure a firm bond and perpendicular positioning, preventing loosening and deformation during later use. CNC models can also use sensors to precisely control the rolling pressure, improving composite accuracy and preventing the profile from bending and becoming unusable after pressing.
