1. Material processing: uncoiling, abrasive blasting, cutting and forming.
(1) uncoiling is to use the uncoiler to uncoil the steel coil into a flat plate.
(2) Abrasive blasting: abrasive particles remove rust and create the surface profile required for coating adhesion.
(3) Cutting materials to the drawing dimensions.
(4)Forming:Forming parts by bending, pressing, rolling, stamping and cutting edges.
2. Welding: processed parts are assembled and welded with corner fittings, door hinges and other components. Fixture stations cover the front end, rear end, side panels, roof, underframe and final assembly.
3. Spraying:Two layers of paint need to be sprayed inside the box and three layers outside the box. Each layer of paint has strict film thickness regulations to ensure that the box paint does not fall off for 3-5 years. So the preparation of the spraying itself is also important, so there is a sanding position specially prepared for spraying before spraying the whole box, so that the whole box can be sprayed.
4. Finishing and final fitting: this section is organized into approximately eight workstations.
(1)Flooring:After the box from the drying room cools slightly, the floor is placed in the beam first, then sealant is applied to all places in contact with the wooden floor, and then the floor is laid.
(2)Nail the floor:Wooden flooring with self-tapping screws, drilling holes in the floor and chassis before tightening.
(3)Install nameplate and ventilator.
(4)Install door tape:Embed sealant tape in the door frame to prevent container leakage.
(5)Cleaning:Remove the residual wood chips and iron chips on the floor.
(6)Locking rod installation:Install the locking rod assembly on the door panel.
(7)Sticker:Stick the customer's logo and box number.
(8) Watertightness and light-leak checks: inspect the container for leakage using the applicable test method.
