Manufacturing Process of the Round Pipe Splice Plate Double Wing Entrance Mesh Metal Door The manufacturing of a Round Pipe Splice Plate Double Wing Entrance Mesh Metal Door is a sophisticated process that combines precision engineering with skilled craftsmanship. It ensures the final product meets stringent performance and safety standards. The core methodologies typically involve a combination of cutting, forming, welding, and finishing techniques, all under strict quality control protocols. Detailed Manufacturing Workflow: 1 Material Selection & Preparation: High-grade raw materials, including various grades of carbon steel and stainless steel sheets, as well as mesh rolls, are meticulously sourced. For instance, structural carbon steel typically conforms to ASTM A36 or equivalent, while stainless steel adheres to AISI 304/316 specifications. Upon arrival, all materials undergo rigorous incoming inspection, verifying chemical composition (via Spectrometer analysis) and mechanical properties (e.g., tensile strength, yield strength, hardness testing) to ensure compliance with design specifications and industry standards like ISO 9001:2015. 2 Precision Cutting & Shaping: Utilizing advanced CNC (Computer Numerical Control) machinery, steel plates for the door frame, critical splice plates, and internal stiffeners are precisely cut. This involves high-definition plasma cutting or fiber laser cutting, ensuring exceptional dimensional accuracy (tolerances typically within ±0.5mm) and clean edges. This precision is vital for the seamless integration of the "round pipe splice plate" component. 3 Forming and Bending: The cut components, particularly the door frame profiles and the unique curved sections of the splice plates designed to conform to round pipes, are then transferred to CNC press brakes. These machines apply immense pressure to precisely bend the metal to the exact angles and radii specified in the CAD designs. This cold forming process ensures structural integrity and dimensional consistency, crucial for the "double wing" alignment. 4 Mesh Fabrication and Integration: The metal mesh panels, forming the core of the door's ventilation and security features, are cut to precise dimensions. Depending on the design, this may involve welding individual wires for robust wire mesh or cutting pre-fabricated expanded metal sheets. These panels are then securely framed and prepared for integration into the door leaves. 5 Advanced Welding & Assembly: Skilled and certified welders assemble the primary door frame, inner stiffeners, and outer skin using high-quality welding processes such as MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding. The pre-formed "round pipe splice plates" are meticulously welded to the main frame, ensuring a robust, load-bearing connection capable of withstanding industrial stresses. All weld seams undergo rigorous inspection, including visual inspection (VT), Magnetic Particle Testing (MPT), or Ultrasonic Testing (UT) as per relevant standards (e.g., AWS D1.1 for steel, ISO 3834 for welding quality management). 6 Surface Treatment & Corrosion Protection: Post-welding, the entire door structure undergoes extensive surface preparation. This involves shot blasting or grit blasting to remove scale, rust, and contaminants, creating an optimal surface profile for coating adhesion. For carbon steel doors, hot-dip galvanizing (conforming to ASTM A123/A123M) provides a metallurgical bond of zinc, offering superior long-term corrosion resistance. Alternatively, a multi-layer high-performance powder coating system (e.g., epoxies, polyesters) or liquid paint systems (e.g., epoxy primer + polyurethane topcoat) are applied. Stainless steel components may undergo passivation (to restore the passive chromium oxide layer) or electro-polishing for enhanced corrosion resistance and a smooth, hygienic finish. 7 Hardware Installation & Final Assembly: High-grade industrial hardware, including heavy-duty hinges (often with sealed bearings for longevity), advanced locking mechanisms (e.g., multi-point industrial locks, panic bars for emergency egress), and handles, are precisely installed. If specified, provisions for electronic access control systems (e.g., electromagnetic locks, card readers) are integrated. The "double wing" mechanism is meticulously aligned to ensure smooth, synchronized operation and proper sealing when closed. 8 Comprehensive Quality Control & Testing: Each Round Pipe Splice Plate Double Wing Entrance Mesh Metal Door undergoes a stringent final inspection before dispatch. This includes full dimensional verification against engineering drawings (using precision measurement tools), functional testing of all moving parts (hinges, locks, panic hardware), visual inspection of welds and surface finishes, and potentially non-destructive testing (NDT) if required. Doors are tested for smooth operation, proper sealing, and alignment. Only products meeting the highest internal quality benchmarks and relevant international standards (e.g., ISO, ANSI, CE for European markets) are approved for shipment.
