The application of heavy-duty angle machine for aluminum doors and windows in the construction industry

The heavy-duty corner joining machine for aluminum doors and windows is one of the core equipment in aluminum door and window processing. It is mainly used for the corner connection process of aluminum alloy door and window profiles, and is a key equipment to ensure the structural strength, sealing performance and aesthetics of the doors and windows. Its application value and specific scenarios in aluminum door and window production are as follows:

1. Core application function: Rigidity connection at the corner

The corner connection of aluminum alloy doors and windows is the core link determining the overall stability of the doors and windows. The heavy-duty corner joining machine uses hydraulic-driven extrusion force to tightly press the corner pieces and the corner cavities of the door and window profiles together, achieving:

High-strength connection: Compared with ordinary corner joining machines, the heavy-duty equipment has greater extrusion force (usually up to several tons), which can make the corner pieces and the profile cavities completely adhere, forming a solid rigid corner structure, effectively enhancing the wind resistance and deformation resistance of the doors and windows, suitable for scenarios such as high-rise buildings, large-sized floor-to-ceiling windows, and curtain wall doors and windows with high structural strength requirements.

Precise angle control: The equipment is equipped with high-precision positioning fixtures and angle calibration devices to ensure that the 90° angle deviation of the doors and windows after joining is minimal, avoiding problems such as "warping corners" and "uneven gaps", ensuring the assembly accuracy and subsequent installation compatibility of the doors and windows.

2. Applicable types of aluminum doors and windows

The high pressure and adaptability of the heavy-duty corner joining machine enable it to cover the processing of various mainstream aluminum doors and windows products:

Break-through aluminum insulated door and window: Suitable for the multi-cavity structure of break-through aluminum profiles, during the pressing process, the insulation strips of the profiles will not be damaged, ensuring the insulation and sound insulation performance of the doors and windows.

Heavy-duty sliding doors, swing doors: These door and window profiles have thick walls and heavy dimensions, and ordinary corner joining machines have insufficient pressure, which can easily cause loose connections. The heavy-duty equipment can achieve stable pressing.

Aluminum alloy curtain walls, sunroom frames: The corner parts of large-span curtain walls and sunroom frames are concentrated in force, and the connection strength of the heavy-duty corner joining machine can meet the structural requirements for long-term outdoor use.

3. Application advantages: Enhancing door and window quality and production efficiency

Ensuring sealing performance: Precise corner joining technology can make the corner gaps of the doors and windows uniform, combined with sealing rubber strips, it can effectively prevent water leakage and air penetration, improving the waterproof and sound insulation performance of the doors and windows.

Simplifying subsequent processes: Doors and windows with high corner joining accuracy do not need additional corrections during the installation of hardware and glass, reducing the rework rate; at the same time, the heavy-duty corner joining machine usually supports semi-automatic or fully automatic operation, with short single-corner joining time, suitable for batch production.

Adapting to irregular profiles: Some heavy-duty corner joining machines can be equipped with different fixtures to adapt to different cross-sectional dimensions of aluminum profiles, meeting the processing needs of personalized aluminum door and window products.

4. Application precautions

Before processing, select matching corner pieces and fixtures according to the profile specifications to avoid profile deformation or loose connections due to incompatible specifications.

Control the hydraulic pressure. Excessive pressure can cause cracks at the corner of the profiles, while too little pressure will not achieve the desired connection strength.
