1.3D simulation, CAE safety analysis and calculation, drawing size accurate to each screw hole, to ensure product consistency. 2 .material: the use of Wuhan iron and steel quality plate, some key position selection of Swedish SSASstrenx 960PLUS imported steel, material flexibility, compression resistance, high safety factor. 3. Laser cutting, high dimensional precision of structural parts. 4. Industrial robot welding, weld uniform and beautiful, no pores, no fake welding. (Robot welding structural parts, never take off welding jacket full life cycle warranty) 5. Sandblasting of structural parts, rust removal, oil removal, welding slag removal. Structural parts stress elimination, structural parts do not deform. 6. All structural parts pickling, phosphating, electrophoresis surface full treatment, structural parts never rust. All structural parts shall be painted separately before final assembly. (Completely solve the problem of rust…
