  • Craftsmanship & Quality

We Work Strictly And Rigorously!

Through fully automated equipment, high-precision processing steps such as cutting, CNC machining, end-face milling, and drilling are executed to ensure 100% seamless mortise-and-tenon joints. This enhances product durability by reducing potential issues such as wear, deformation, and other long-term quality concerns.

Automation eliminates the impact of external variables, thereby improving production efficiency and shortening manufacturing cycles, all to meet consumers’ demands for timely installation and project scheduling.

Step 1: Drilling And Milling

Drilling involves creating precise holes in the profile for the installation of hardware, screws, and other components. Accurate positioning is essential to avoid repeated adjustments or misalignment.

Milling includes end milling and CNC milling:

  • End Milling is used to shape the ends of profiles for joint connections.
  • CNC Milling is applied to create special features such as drainage holes, lock slots, and other customized shapes.

Step 2: Stamping

Primarily used for cutting through profiles and processing hardware hinge positions, such as corner connector holes, joint fitting holes, and pin holes, ensuring precision and consistency in structural connections.

Step 3: Preparation before Assembly

Inspection of hardware components, inspection of profiles, preparation of tools.

  • Assembly of Hardware Components:Window hardware, door hardware.
  • Debugging of Hardware Components:Opening and closing tests, overlap and gap inspection, hardware functionality test, sealing performance check.
  • Overall Inspection and Adjustment:Multiple tests and fine-tuning of details.

Step 4: Product Inspection

  • Raw Material Inspection: Aluminum Alloy Profiles, Glass, Hardware Accessories
  • Finished Product Inspection: Appearance Inspection, Dimensional Inspection, Structural Inspection

Step 5: Final Inspection and Packaging Procedures

  • Cleaning & Inspection:Clean the surface to remove dust, oil, and debris. Check for scratches, dents, deformations, and ensure hardware is securely installed and functions properly.
  • Surface Protection:Apply protective film to aluminum profiles to prevent damage during transport and installation.
  • Cushioning:Fill foam, EPE, or cardboard around the product to absorb impact and prevent movement inside the packaging.
