The thermal break aluminum profile strip installation equipment is a core specialized piece of equipment for producing thermal break aluminum profiles. Its core function is to achieve a composite connection between the thermal break strip and the aluminum profile, ensuring the thermal insulation performance of thermal break aluminum doors and windows. The related technologies can be summarized from three aspects: process scheme, core equipment functions, and key technical points.
Mainstream Process Schemes and Technical Routes
Currently, the industry mainstream uses two process routes: the two-step method and the three-step method, suitable for different production scales:
Two-Step Method: Integrates the tooth cutting and strip installation into the same machine (tooth cutting and strip installation integrated machine), followed by a rolling composite machine to complete the production. This two-machine production line is suitable for small to medium-sized production capacities below 3000 tons per year. Its advantages are shortened processes and reduced floor space costs.
Three-Step Method: Divided into three independent machines: a tooth cutting machine, a strip installation machine, and a composite machine. Suitable for large-scale production above 3000 tons per year, offering higher overall production efficiency and larger capacity.
Both solutions share the same core principle: processing is achieved through "toothing to increase biting force → strip insertion and positioning → rolling and compounding," differing only in the degree of process integration.
Functional and Technical Characteristics of Core Equipment A complete strip insertion production line mainly comprises three types of equipment, each performing key technical functions:
Toothing Machine/Toothing and Strip Insertion Integrated Machine: Its core function is to use a high-speed rotating toothing cutter to create tooth marks at the groove where the thermal insulation strip is inserted into the aluminum profile. This significantly increases the lateral shearing force between the thermal insulation strip and the aluminum profile, preventing the thermal insulation strip from falling off later.
Mainstream integrated machines integrate an automatic strip insertion mechanism, completing strip insertion simultaneously with toothing, reducing manual operation and improving efficiency. Most machines support cutter head position adjustment to adapt to different profile specifications, and some CNC models also support parameter storage, eliminating the need for repeated adjustments during production changes.
Thermal Insulation Strip Insertion Machine: Independent thermal insulation strip insertion machines rely on toothed rollers or feeding wheels to accurately insert the thermal insulation strip into the corresponding slots of two aluminum profiles. Some high-end models are equipped with a special clamping system for greater insertion force and also feature an electric cutting function, allowing direct cutting of disc-shaped thermal insulation strips, suitable for high-volume production.
Standard Parameters: Insertion speed is generally adjustable up to 110 meters per minute, suitable for thermal insulation strips with a height range of 12-40mm.
