Production Line
-
Tray (Bucket) Fabrication:
-
Deep Drawing: A hydraulic press uses heavy dies to stamp flat sheet metal into the initial 3D tub shape.
-
Trimming & Flanging: Excess metal is trimmed around the perimeter, and a flanging or spinning machine curls the edges to eliminate sharp rims and increase structural rigidity.
-
Punching: Presses stamp mounting holes for bolts and frame attachment.
-
-
Frame Fabrication:
-
Pipe Cutting & Bending: Steel pipes are cut to size and formed into handles, chassis legs, and front supports using CNC or hydraulic tube benders.
-
Flattening & Drilling: Pipe ends are flattened, pierced, or notched where they connect to the tray, axle, or crossbracing.
-
-
Welding & Sub-assembly:
-
Frame components, leg braces, and axle brackets are joined together using manual or robotic welding setups.
-
-
Surface Treatment & Finishing:
-
Metal parts pass through automated washing and degreasing stations.
-
The frame and tray undergo powder coating or dip-painting, followed by high-temperature curing ovens for rust resistance and durability.
-
-
Final Assembly & Packaging:
-
Components (tray, tubular frame, axle, rubber wheels, handles, and hardware) are assembled into finished units or bulk-packed as knock-down kits for efficient shipping.
