Vertical Eco-BBQ Grill "MANGAL"

Engineering Process & Technical Solutions:

The primary engineering goal of this project was to design a highly efficient, space-saving, and heavy-duty vertical BBQ grill. The design had to withstand extreme thermal cycles, resist thermal warping during continuous coal burning, and feature rapid assembly without requiring any mechanical tools.

• 1. 3D MODELING & SHEET METAL UNFOLDING IN SOLIDWORKS We performed comprehensive structural modeling of the collapsible grill body. Our team precisely calculated bending allowances and deformation radii adjusted for our CNC press brake tooling. This achieved optimal mounting tolerances, preventing the heated metal from binding during disassembly.
• 2. PRECISION CNC FIBER LASER CUTTING High-speed nesting and high-fidelity cutting of structural components were executed on fiber laser cutting systems. The main 3.0 mm walls and removable grate bars were fabricated from high-strength structural grade steel. The laser's 0.05 mm accuracy ensured flawless interlocking tab-and-slot fitting.
• 3. MULTI-AXIS CNC HYDRAULIC BENDING All load-bearing structural ribs, heavy-duty support brackets, and skewer guide rails were formed using CNC press brakes. These pre-engineered stiffeners effectively eliminate deflection and geometric warping under extreme heat exposure from firewood combustion.
• 4. MODULAR SLOT-AND-TAB COUPLING (NO-WELD ASSEMBLY) To completely prevent residual structural stresses caused by localized welding heat zones, the assembly mechanism is entirely interlocked via a mechanical tab-and-slot design. The unit can be effortlessly transformed into a rigid, stable setup within 1 minute without using screws or rivets.
• 5. HEAT-RESISTANT INDUSTRIAL COATING To protect the final assembly against moisture oxidation, heavy corrosion, and thermal degradation, a specialized heat-resistant silicone-based enamel was applied. The subsequent thermal curing guarantees resilience against direct flame exposure and thermal shock loads up to 800°C.
• 6. CO2 LASER PROCESSING FOR PROTECTIVE CARRYING CASES To deliver a complete transportable product, precision CO2 laser systems were deployed to cut heavy-duty, water-repellent, and tear-resistant fabric panels. The resulting tailored carrying case ensures clean, safe handling and organized storage in a vehicle's luggage compartment.
